Endangered Plants

All over the world, we always known about the endangered animals, but what are the most endangered plants?

They might not be as stirring or attractive as animals, but they are just as important to the ecosystem and humanity depends on that ecosystem.

In this articles we’ll talking about the most threatened plants today. Almost all this kinds are classed as critically endangered by the International Union for Conservation of Nature (IUCN).

These plants inhabit some of the most unreachable, distant parts of our planet. They are threatened by habitat destruction, illegal collection, poaching, and competition with invading species.

Some of this plants:

  1. Attenborough’s pitcher plant (Nepenthes attenboroughii)
  2.    Western Prairie Fringed Orchid ( Platanthera praeclara )
  3. Rafflesia Flower (Rafflesia arnoldii )
  4.  Georgia Aster (Symphyotrichum georgianum )
  5. Wiggin’s Acalypha (Acalypha wigginsii )
  6. Texas Wild Rice (Zizania texana )
  7. Howell’s Spectacular Thelypody (Thelypodium howellii ssp. spectabilis )
  8. Ouachita Mountain Goldenrod (Solidago ouachitensis )
  9. Enrubio (Solanum drymophilum )
  10. (Agave arizonica )
  11. Stenogyne Kanehoana .

In the next article w’ll taking about each kind of this plants.

Magnetic Technology and Agricultural Sector

Among the stresses in agricultural sector worldwide, the increase of soil and water salinity is considered the major stress. This is particularly emerging in developing countries like MENA region. The chronic water shortage in the Middle East North Africa (MENA) region is a perplexing issue, undoubtedly because various operational sectors. The use of magnetically treated water is an important factor in achieving sustainable development in the agricultural sector. It improves plant production, reduces fertilizer use, and increase water irrigation efficiency, Also, use of magnetically treated irrigation water reduced soil pH but increased soil E C and available P in different plants. From other side, there are some beneficial effect of magnetically treated irrigation water, particularly for saline water and recycled water, on the yield and water productivity of treated plants.

The technology of magnetic water has widely studied and adopted in field of agriculture in many countries, Magnetic technology considered as one of the most promising technologies that can improvement and treated with different problems in the agricultural sector, such as the decrease in quantities of  irrigation water, in the same time there are global demands for food due  to the expected population increase around the world by 2050 .Where the world’s population will reach about 9 billion people, which will need more food production by about 60 percent of current production to meet the needs of mankind.

Magnetic technology is used in several ways to improve agricultural production like:

  1. Treating seeds and seedlings, leads to acceleration of plant growth activates proteins formation and root development (Rakosy-Tican et al., 2005).
  2. or to treat irrigation water
  3. and saline-affected soils,

which are used to increase seed germination and improve seedling growth and crop productivity, the most widespread use of magnetic technology in agriculture is treatment of irrigation water to increase its efficiency and allow the use of available water sources even low quality water, as well as soil salinity treatment.

Magnetic field changed the characteristics of cell membrane, effected the cell reproduction and caused some changes in cell metabolism.

Magnetic treatment of water improve different water characters, also,  improve the vegetative growth and productivity of plants either quality  or quantity, the reason of this effect can be searched in the presence of paramagnetic properties in chloroplast which can cause an acceleration of seeds metabolism by magnetic treatment

A magnetic field treatments was shown to induce seed germination, shoot development, fresh weight and plant length, fruit yield per plant and average fruit weight (Abobatta 2015).

Static magnetic fields has positive effects on the metabolism and growth of different plants, Roots seem much more susceptible to the magnetic field than shoots (Kato et al., 1989), from other side Electromagnetic fields can alter plasma membrane structures and functions.

In general , treatments with magnetic field the plant metabolism is changed and it is possible to induce some phenotypic and genotypic effects able to stimulate the plant productivity.

Croton plant

 Croton plant

Codiaeum variegatum

Family: Euphorbiaceae


                                    Croton has glossy, leathery leaves that are very variable in shape, highly colored and variegated.  The leaves can be ovate or linear and variegated with pink, orange, green, brown, yellow and white.

Croton is an exotic looking plant that is grown in warm greenhouses or conservatory or as a indoor plant.

It is native to Indonesia, Malaysia, Australia and the western Pacific Ocean islands, and growing in open forests and scrub.


                          It is an evergreen shrub growing to 3 m (9.8 ft) tall and has large, thick, leathery, shiny evergreen leaves, alternately arranged, 5–30 cm long and 0.5–8 cm broad. The inflorescence are long racemes 8–30 cm  long, with male and female flowers on separate inflorescences;   the male flowers are white with five small petals and 20–30 stamens, the female flowers yellowish, with no petals.

The fruit is a capsule around 1 cm diameter, containing three 6 mm seeds. The stems contain milky sap that bleeds from cut stems.


                        In tropical climates, crotons make attractive hedges and potted patio specimens, valued for their striking foliage. They only survive outdoors where temperatures do not normally drop below 10° to 13°C in winter; colder temperatures can cause leaf loss.In colder climates, the plants are grown in greenhouses or as house plants.

The cultivated garden crotons are usually smaller than the wild plant, rarely over 1.8 m tall, and come in a wide diversity of leaf shapes and colours.


                             For a plant with this incredible diversity, it’s amazing there is only species (C. variegatum). 

Crotons are often subdivided by their leaf type: curling, twisted, oak leaf, narrow, broad, oval, etc.

Also, sometimes different plants grouped under the name  Codiaeum variegatum var. pictum (Lodd.) Müll. Arg., though this is not botanically distinct from the species and usually treated as a synonym of it.

For that, there are several hundred of croton cultivars, selected and bred for their foliage. Depending on the cultivar, the leaves may be ovate to linear, entire to deeply lobed or crinkled, and variegated with green, white, purple, orange, yellow, red or pink.

There are different varieties like Dreadlocks, Ann Rutherford, Mona Lisa, and Irene Kingsley.


                            Crotons are easily propagated through stem cutting. Preferable usage  rooting hormone to increase the odds of success.

Crotons sometimes produce “sprouts,” or shoots that are completely different from the parent plant. These can be potted up independently.

Seeds used only in breeding program for scientific purposes,

                       Only cuttings will produce a plant that is identical to the parent.


                          As with many of the Euphorbiaceae, the sap can cause skin eczema in some people. The bark, roots, latex, and leaves are poisonous, containing the toxin called 5-deoxyingenol, also, the latex has caused eczema in some gardeners after repeated exposure.

The plant contains an oil which is violently purgative and is suspected of being a carcinogen. Consumption of the seeds can be fatal to children.

         Chewing the bark and roots may be cause burning of the mouth.

Lucuma Tree

Lucuma Tree
Pouteria lucuma,

Family: Sapotaceae

A fruit tree of the Andes, in Ecuador, the tree is called lugma, from other side,it’s called lucuma in Chile, The native habitat of this tree is the high Andean valleys of Peru, Chile, and Ecuador.

It has been used  by the Incas for at least 2,000 years, p.d., and still is not practically known in the rest of the world.


                  Lucuma is a handsome tree, small to moderately tall, with slightly leathery leaves, it sometimes grows as a central leader tree, but more usually it has multiple leaders.

Lucuma  is a subtropical fruit tree of Andean valleys, especially in Peru, also it’s grown in Ecuador, Colombia, north of Chile and Bolivia.

It is being cultivated  in Costa Rica, Mexico, Hawaii, Australia and New Zealand. Also there is some trials to planting in Florida and California .

Peru is the First producer for the dried pulp market, by  (16,000 metric tonnes of fresh fruit in Peru alone (given 8 tonnes per hectare).


              The tree  grow will across a wide range of soil types, including somewhat calcareous or even slightly saline soils, so long as the soil is fairly well drained. the tree need good drain to avoid root rot diseases.


                         Trees flowering in mid winter to spring. The flowers are white  to yellow, and narrowly tubular.  The male anthers are arranged around the ‘mouth’ of the flower ‘tube’. The female style projects from the bud prior to the flower opening, may be they can then pollinate the female part, if it hasn’t already been done.

There are some  author says lucuma trees are self fertile, and “appear to be insect pollinated”, the fruit mature after  8 or 9 months to go from flower pollinating.

“Meanwhile in the Andes it flowers and fruit year round”


                          lucuma tree almost propagation by seeds, for that there are different varieties, for example in Peru, over 100 improved lineages have been identified, either with heavier fruit production, or improved fruit quality.

In Chile La Molina University start deliberate breeding program to get new species with highly production and better fruit quality, now there are ‘San Antonio’, ‘Merced’, and ‘Vergata’ varieties are known as Chilean cultivars .

In New Zealand there is only one cultivar  ‘La Molina’, which was at one time available from a nursery, it is a Peruvian cultivar, the fruit have soft flesh , with orange flesh.

Buddha Hands Fruit

Buddha Hands Fruit

Citrus medica var. sarcodactylus

This lemon like citron (Citrus medica var. sarcodactylus) is not usually eaten fresh, (although the rind may be candied and is sometimes used for zest), but it’s fragrant and said to have some medical qualities. It is said that the fragrance of a single fruit can perfume a room for weeks.

The Origin:

                                    The origin of this kind of citron is commonly traced back to the Far East, probably northeastern  India  or China, where most domesticated citrus fruits originate.


                   Buddha’s Hands { Citrus medica var. sarcodactylis } one of citrus kinds, like any other citrus variety, it is a  small tree or shrub  with long, irregular branches covered in thorns, the leaves are large grow up to 15 cm, oblong pale, green, Its white flowers grow in fragrant clusters and tinted purplish from the outside, the fruit contain only the white part of the fruit and sometimes a small amount of acidic pulp, but many varieties  are completely juice-less and some are seedless.

The fruit is segmented into finger-like sections, resembling a human hand, but the different cultivars and variations of this citron variety form a gradient from “open-hand” types with outward-splayed segments to “closed-hand” types, in which the fingers are kept together, also, there are half-fingered fruits, in which the basal side is united and the apical side fingered.


                            Trees can be grown from cuttings taken from branches two to four years old, it is very commonly grafted onto sufficient rootstock.


               As most kind of citrus, the plant is sensitive to frost, as well as intense heat and drought, It grows best in a temperate climate.

Traditionally, the fruit was prized by the Chinese for its resemblance to a hand with the fingers outstretched. The buddha’s-hand citron was a popular plant motif in the art of the Ming dynasty. Besides its association with the Buddha the plant suggested wealth because of its resemblance to an outstretched hand. It remains popular at New Year’s and is said to bestow good fortune.

Magnetic Agriculture

Magnetic agriculture used to reduce water or soil salinity  problems, they proposed an auxin-like effect of the Magnetic Field on germinating seeds, also, irrigation with magnetically treated water or/and magnetic seed treatment are friendly environmental techniques.

Therefore, they take an important place in the list of  environmental clean methods and harmless technology.






White strawberry




                             The pineberry is a hybrid strawberry cultivar with a pineapple-like flavor, white flesh coloring, and red seeds.

Pineberries are actually the oldest strawberry variety.  Originally strawberries were white in South America (Fragaria chiloensis) and red in North America (Fragariea virginiana).


In 2010 the pineberry was introduced on April 1st in the UK. Many media thought it was an April fools’ joke and believed the pineberry did not exist. However when it turned out the introduction of the pineberry was for real, this special strawberry got a lot of media attention.

Interantional PULSES Year 2016

International Year of Pulses (IYP).

        On December 21st 2013, the General Secretary of the United Nations in New York voted to proclaim the International Year of Pulses 2016 (IYP).


           An International Year designation provides an extraordinary opportunity to raise awareness and to celebrate the role of  pulses in feeding the world.

          United Nations, led by its Food and Agriculture Organization (FAO), to raise awareness about the protein power and health benefits of all kinds of Pulses, boost their production and trade, and encourage new and smarter uses throughout the food chain.

           Even more prominently, it will be a galvanizing moment to draw together key actors to further the contributions pulses make to health, nutrition, and sustainability.


            What’s the Pulses?

           Pulses, or grain legumes, are any DRY edible seed in the family of legumes (Fabiaceae), include 12 crops such as dry beans, dry peas, chickpeas, and lentils, which are high in protein, fiber, and micro-nutrients.

Pulses Varities

             pulses, are not simply cheap and delicious; they are also highly nutritious source of protein and vital micro nutrients that can greatly benefit people’s health and livelihoods, particularly in developing countries.

           Pulses present many opportunities for decreasing the environmental footprint of food production, especially by fixing nitrogen to progress soil quality.

Moreover, enhancements in pulse productivity could be especially impact in the increasing world.

           Pulses are important food crops for the food security of large proportions of populations,  particularly in Latin America, Africa and Asia,  where pulses are part of traditional diets and often grown by small farmers.

          There’s  a short video  describe pulses important and  highlighting unique opportunities for pulses to contribute to the future of food security.


             Pulses can contribute significantly in addressing hunger, food security, malnutrition, environmental challenges and human health.

The water efficiency of pulses allows the plants to enrich soil where they grow and reduce the need for chemical fertilizers.

Nutritional values of Pulses:

  • Just one portion of chickpeas contains 1.5 times as much iron as a 3-ounce portion of steak, and pulses are a division of the cost of other protein sources.

  • pulses have double the proteins found in wheat and triple the amount found in rice.

  • They are also rich in micro_nutrients, amino acids and b-vitamins.

           Pulses are vital food crops for the food security of large extent of populations, Particularly in Latin America, Africa and Asia, where pulses are part of traditional diets and often grown by small farmers. Furthermore, improvements in pulse productivity could be  impact in the developing world.

           Pulses can contribute significantly in addressing hunger, food security, malnutrition, environmental challenges and human health.

Environment Benefits of Pulses:

1- Pulses offer many opportunities for reducing the environmental footprint of food production.

2- Pulses fixing nitrogen  which increase soil fertility and improve soil quality.

3- Pulses use less quantity of water, just 43 gallons of water can produce one pound of pulses.

4-production of pulses emits only 5 percent of the greenhouse gas emissions associated with beef production.

International Pulses  trade:

                                                                      World production from pulses reach to 60 MT per year, but there’s only 6 million’s  MT  available for trading. meanwhile, The Middle East , North Africa and Southeast  Asia’s regions are biggest producer , consumer and importer of pulses, ( import around MT per annum).
