硼与乙烯调节剂对棉花营养和产量的影响

THE EFFECTS OF ETHYLENE REGULATORS ON NUTRITION AND YIELD OF COTTON

在土培条件下，对棉花喷施乙烯的抑制剂（ＣｏＣｌ＿２）、拮抗剂（ＳＴＳ）和促进剂（Ｅｔｈ），研究其对棉花营养和产量的影响。结果表明：缺硼使棉花叶片及蕾的乙烯释放量增加。调节棉花乙烯释放量，能改变棉花叶片过氧化物酶和多酚氧化酶的活性，影响棉花叶片Ｎ、Ｐ、Ｋ的含量，并最终影响棉花的产量。

The experiments were conducted under soil culture condition to study the effects of ethylene regulators,includes the inhibitor(CoCl_2),antagonist(STS) and the promoter(Eth),on nutrition and yield of cotton. The results indicate that the release of ethylene in cotton leaves and squares were increased while B-deficiency. That can change the activities of peroxidase (POD) and polyphenol-oxidase (PPO), influence the content of N,P,K in leaves, alter the yield and height of cotton after we regulate the release of ethylene.
