摘要
田间试验研究不同Zn肥施用量对苦瓜叶片C代谢及相关酶活性的影响结果表明 ,低Zn胁迫时苦瓜上位和下位叶片蔗糖、可溶性糖、淀粉、Zn含量、蔗糖磷酸合成酶活性和碳酸酐酶活性均显著下降 ,而酸性转化酶活性、中性转化酶活性和淀粉酶活性显著提高 ,且它们之间均呈显著和极显著相关性。
Effects of zinc on carbon metabolism and its enzymes activities in leaves of balsam pear were studied by field trial . The results show that in the control plants stressed under a low level of zinc, there appear lower contents of sucrose, soluble sucrose ,starch and zinc, lower activities of carbonic anhydrase(CA) and sucrose phosphate synthase (SPS). How- ever , the activities of amylase, acid invertase(AI)and neutral invertase (NI)in the upper and lower leaves are higher in CK than in other treatments. There is a significant correlation between the physiological properties.
