Poleva J. Means of the chemical defence of the phytobiogeotsenosis as ecological factor (influence, optimization, stability, productivity).

Objects - phytobiogeotsenosis of lines Zea mays. The aim is to study the influence of herbicides as ecological factor on phytobiogeotsenosis. Methods - element and amino-acids analysis of whole grain in ontogenesis and anatomic parts, allocation of fiber bodies from endosperm of a grain Zea mays L. with subsequent amino-acids analysis and microphotoshooting the allocated organelles.The pecularities of the herbizides of different ways of action have been studied on the samples of phytobiogeotsenosis Zea mays L. There has been stated the correlation of the use and harm as a result of the applying of the chemical means of defence while using Zea mays L. in phytobiogeotsenosis. The specific forms of reaction of the mays were defined on the basis of the completed analysis of the phyto under research and it was shown the adaptivity of physiology of biochemical processes in the growing grain of the phyto to the human ecological factors in phytobiogeotsenosis Zea mays L. The directions of the optimization ofthe using of the chemical means of defence of phytobiogeotsenosis, namely Zea mays L. were offered, which might influence the raising of productivity and harvesting of the phyto plants and might give minimum harm to the destruction of the ecological balance and purity of phytobiogeotsenosis. Sphere - agriculture.
