摘要

用琬豆Sparkle及其单基因突变体E107进行水培试验, E107各处理的地上部Fe、Mn含量均比Sparkle高, 但根部食量则相反。E107对Fe、Mn具有较高的吸收效率, 但不在根系中贮存, 而是不断运输到地上部分, 在叶片中积累乃至伎叶片中毒坏死, 充分表现了对Fe、Mn具较高的转移效率。图6参18

Abstract

Iron stress response of mutant E107 and its parent(cv ^Sparkle^)of Pisum sativum were studied in determining the root reduction activities, H~(+)excretion and Fe、Mn contents of shoots and roots under controlled conditions. Root ferric reduction activities and H~(+)excretion in E107 were higher than that in Sparkle. In contrast to those in the roots, the Fe, Mn contents of shoots in E107 were significantly higher than those in Sparkle. It can be concluded that not only the mobilization, but also the uptake and translocation of Fe and Mn in the single gene mutant E107, are very efficient as compared with those in its parent Sparkle.

Key words: Fe-deficiency;Single gene mutant;Fe-efficiency;Mn-efficiency
