Plants themselves can destroy pesticides

Chinese scientists have found a way to combat excessive pesticides. Plants themselves can get rid of harmful excess. It is only necessary to inject them hormone rosta.Pestitsidy - a spectrum of chemicals used in agriculture for pest control. This group includes herbicides (substances that destroy the weeds), insecticides (insects), fungicides (fungi) and several other classes. Typically, these substances have a negative impact on one or another species. They are extremely toxic, and culture, too protected from pests, can either be killed themselves, or simply become poisonous. Chinese scientists have studied the mechanisms that allow cucumbers to process surplus yadov.Veschestvom stimulating removal of pesticides, was 24-epibrassinolide (DL). In 1979, he singled out the pollen of rape and later found that it stimulates the growth of plants. Then began the mass production of growth hormone. Cucumbers without yadovDlya experiments used cucumber seedlings (Cucumis sativus L. cv. Jinyan No. 4), grown on a uniform methodology. As soon as the sprouts appear fourth leaflets with them began to conduct experiments to measure the active concentrations of chlorophyll and pestitsidov.Dlya all parallel measurements, scientists have used the following method: a core group of plants were pretreated with 24-epibrassinolide, and the next day - with solutions of pesticides. Control group was treated only with pesticides. And then conducted quantitative measurements with listyami.Klyuchevym has been studying the effect of chlorpyrifos - pesticides from spreading to the amount of chlorophyll in leaves. All experiments in this case based on the absorption of CO2 and oxygen evolution. Processing chlorpyrifos reduced the absorption of CO2, thereby suppressing the development of plants. But after the pretreatment (DL), the active concentration of chlorophyll did not fall so much. If simple processing pesticide level of chlorophyll decreased by 70%, then for the protection of digital libraries - only 35%. Concentration quickly returns to "normal" level. A similar effect was demonstrated for a number of other pestitsidov.Kontsentratsiya all pesticides after necessary treatment was also significantly lower in a day. After a series of kinetic (measuring rates of processes) and genetic testing, scientists discovered the cause of this phenomenon. 24 epibrassinolide activates gene expression, "processing" toxins, ie, activates the synthesis of these proteins, genes that are involved in the decomposition of pesticides. However, in this capacity also has limits: if you pour concentrated pesticide plant, it has nothing spaset.Rezultaty works are published in the Journal of Agricultural and Food Chemistry. In them, however, says nothing about the side effects of hormone-treatment plant. Perhaps this is a topic for future research.
