Wheat is grown on more than 240,000,000 hectares (590,000,000 acres), larger than for any other crop. World trade in wheat is greater than for all other crops combined. With rice, wheat is the world's most favored staple food. Wheat provides more nourishment for humans than any other food source.The importance of wheat not only embodied in the nutritive value.According to a research from SCIRP,when it is a plant,its allelopathic potential decides its eco-friendly trait for it can effectively reduce herbicide uses.
According to the World Health Organization and the United Nations Environment Programme report, in the world, there are over 100 people herbicide poisoning, of which 10 million people died each year. In the developing world, the situation is much worse. Based on animal experiments, IARC confirmed that the widely use herbicide can be carcinogenic. It is estimated that the number of cancer patients with chemical herbicides accounted for about 20% of the total number of cancer patients.
Maybe we can make use of its allelopathic potential to implement “green food”,reducing the harm made by herbicide.
