本文研究了玉米幼苗在干旱处理下~(32)P的吸收,以及油菜素内酯(BR)和钙浸种对磷素营养的生理效应。结果表明,玉米幼苗根系对磷的吸收和向叶部转移量随干旱强度增大而减少;油菜素内酯和钙有增加根系吸收表面积 提高叶片相对含水量和根中ATP含量、促进磷的吸收和转移及缓解干早的作用
In this paper, the absorption of ~ (32) P in maize seedlings under drought and the physiological effects of brassinolide (BR) and calcium on phosphorus nutrition were studied. The results showed that the uptake of phosphorus and the transfer to the leaves of maize seedlings decreased with the increasing of drought intensity. Brassinolide and calcium increased the root absorption surface area and increased the relative water content of leaves and the content of ATP in roots, and promoted the absorption of phosphorus And transfer and ease dry early role
