摘 要 ：用１０－５ｍｏｌ／ＬＢＡ处理去顶去根花生幼苗库叶２４ｈ内．蔗糖磷酸合成酶和细胞质果糖－１，６－二磷酸酯酶活性逐渐增加．酸性转化酶活性降低．使蔗糖含量提高，α－淀粉酶活性的增强，促进淀粉分解。ＢＡ处理２４ｈ后，随着蔗糖磷酸合成酶和细胞质果糖－１．６－二磷酸酯酶活性的减弱．酸性转化酶活性逐渐增加．蔗糖含量减少，有利光合碳在淀粉的积累．

Abstract:Decapitated-derooted peanut seedlings (Arachis hypogaea L.) were smeared with 10-5 mol/L benzyladenine (BA) solution on the surface of sink leaves. 0-24h after BA treatment, the activities of sucrose phosphate synthetase (SPSase) and cytosol fructose-1, 6bisphosphatase (F1, 6Pase)were gradually increased. The decrease of acid invertase activity resulted in increasing amount of sucrose content and the increase of α-amylase activity caused the reduction of starch content. 24-48h after BA treatment, however, the activities of SPSase and F1, 6Pase decreased and acid invertase increased gradually in sink leaves. The amount of sucrose was reduced and photosynthetic carbon was favorable to the accumulation of starch.
