THE STUDY OF HEAVY METALS (Ni, Zn, Cu, Pb) IN THE VEGETATIVE ORGANS, HARVEST AND GROWING SOIL OF POTATOES, WHEAT AND WILD BLACKBERRY

摘要

Here was discussed the researches of heavy metals transition to the root, steam and leaf from sprout growing soil of potatoes, wheat and wild blackberry. The growing soil data comparison shows that soils differ with heavy metals content. Heavy metals content differs a little in potato leaf and tube. This gives an opportunity to suggest a new method that is to define heavy metals content in potato tube before harvesting, which will have great organizational and economical importance. According to our study in different organs of potato, wheat and blackberry the quantity of Zn, Cu, Ni, Pb is proportional to their content in soil; Zn. Cu. Ni. Pb contents in vegetative organs of potato, wheat and blackberry and harvest are different; Zn, Cu, Ni, Pb contents in potato tube, wheat grain and blackberry fruit is the least as compared with vegetative organs; The contents of heavy metals in potato tube can be defined by means of new method, before harvesting, by analysis data of green leaf. Growing soils have different contents of heavy metals.
