作者曾著文报道:禾谷类作物开花后遭受干旱胁迫时,籽粒生长将日益依赖于作物贮藏物质的转移(该文之译文已在本刊上期发表—编注)。这种现象与短暂的光合作用有关,与作物的遗传变异也有关系。上述报道中论及开花后喷化学干燥剂(氯酸镁)能完全破坏作物的光合源,可作为揭示籽粒生长过程中物质转移方面遗传变异的一个 The author has authored a paper reporting that grain growth will increasingly depend on the transfer of stored matter when the cereal crops are exposed to drought stress after flowering (this article has been published in the previous issue - edition). This phenomenon is related to transient photosynthesis and to the genetic variation of crops. In the above report, spraying chemical desiccant (magnesium chlorate) after flowering can completely destroy the photosynthetic source of crops and can be used as one of the genetic variations in substance transfer in grain growth
