原始语种摘要: The objective of this research was to investigate the effect of short-term heat (2 h., +400C) and cold (2 h., +20C) stresses on accumulation and distribution of cytokinin (CK) in 7 and 14-day-old seedlings of the frost resistant Triticum aestivum L. cultivar Volodarka. A high performance liquid chromatography method has been used to provide a qualitative and quantitative analysis of hormones in leaves and roots. It was shown that in the early stages of growth (7 days) after exposure to high temperature the total content of cytokinin in roots increased 1,6 and in leaves in 2,55 times. The most pronounced changes were registered for trans -zeatin ( t -Z) and izopenteniladenozin (iPa) in roots and for zeatinriboside (ZR), izopenteniladenin (iP) and iPa in leaves. After...
