Аннотация

The phosphorus content and yielding capacity of the wheat seed produced during field experiments under the influence of 13 variants of mineral nutrition upon 3 modes of soil moisture have been studied. The greatest accumulation of phosphorus in seeds with their less yielding capacity occurs upon water deficit soil. The intermediate phosphorus content in seeds with the higher yielding capacity of the seeds are formed at the optimum soil moisture. The lowest phosphorus accumulated in waterlogged soil. Between the phosphorus content in the seeds and soil phosphorus level is no direct relationship. These data are interpreted as the result of the decay of vegetative tissues in the final stages of ontogeny and transfer the products of hydrolysis of organic compounds into the wheat seeds. Keywords: wheat, mineral nutrition, soil moisture, seed phosphorus, seed yielding capacity.
