绿色植物生长调节剂(ABT6^#)在黄瓜上的应用效果及作用机理

摘要: 绿色植物生长调节剂是中国林业科学研究院ABT研究开发中心继研制开发出ABT 系列生根粉后于近几年新推广的1种新型植物生长调节剂，通过发芽试验、育苗试验和田间生产试验系统地研究了绿色植物生长调节剂对黄瓜应用效果及促进黄瓜生长的作用机理，结果表明经绿色植物生长调节剂处理后黄瓜发芽率提高6．34％，发芽势提高17．04％。与对照相比，黄瓜苗期茎尖过氧化物酶含量提高16．84％，根系脱氢酶含量提高62．16％；黄瓜根尖、茎尖内源激素含量均向正效应方向调控；受绿色植物生长调节剂的影响，田间黄瓜营养生长旺盛，产量提高10.58%,应用效果显著。

Abstract: The experiments on application effect and action mechanism of ABT on cucumber were carried out and three trials(seed germination trial，seedling trial and field tria1)were conducted．The results indicated that ABT6 has positive effect on the content of internal hormone in stem apex and root of Chinese cabbage．The rate and potential of seed germination，the peroxdase content in seedling stem apex，the dehydrogeniase content in seedling root and the yield of Chinese cabbage treated with ABT6^#，increased by 6.34％，17.04％，16.84％，62.16％，and 10.58％，respectively as compared with contro1．
