| 摘 要： | 以番茄‘辽园多丽’品种为材料, 比较花蕾期、开花期及幼果期的小花(果) 柄对乙烯诱导脱落的敏感性。结果表明, 开花期小花柄最易接受乙烯的诱导而脱落, 20μL·L -1乙烯是最佳诱导浓度。该浓度处理的小花柄在脱落后期, 各部位POD、CMC-Na 酶及Exo-PG活性升高, 但不同部位的POD、CMC-Na酶、Exo-PG活性及可溶性蛋白含量变化不一致。

| Abstract: | Pedicels of Lycopersicon esculentum Mill ‘liaoyuanduoli’were harvested at three developmental stages , namely at the anthesis , bud stage and on the tenth day after flower. The abscission sensitivity of pedicels explants induced by ethylene was investigated. The results were showed as following : Anthesis was the stage most liable to shell of pedicels explants induced by ethylene and the optimum concentrate was 20μL·L-1 . There was a significant increasement in the activity of POD and CMC-Na enzyme in abscission zone , distal side and proximal side of pedicels explants at the end of ethylene treatment in optimum concentrate. However , no clear relationship between the activity of these enzymes and the soluble protein content was observed. |
