Abstract

Exposure of white bean seedlings to phytotoxic burdens of Co, Ni, or Zn reduced the export of (14)C-photoassimilates from the nearly fully expanded unifoliate leaves. Little (14)C reached the major sink areas, the young trifoliate leaves and the root tips, of seedlings exposed to metal. The unifoliate leaves accumulated sucrose, reducing sugars, and starch. These effects were evident within 1 or 2 days.

摘要

暴露于钴、镍或锌的植物毒性负荷下的白豆幼苗减少了（14）C-光合作用产物从近完全展开的单叶中的输出。暴露于金属的幼苗中，很少有（14）C 到达主要的汇区，即年轻的三叶叶和根尖。单叶积累了蔗糖、还原糖和淀粉。这些影响在 1 或 2 天内就显现出来了。
