【摘要】 通过发芽、育苗和田间生产试验 ,系统研究了绿色植物生长调节剂在大白菜上的应用效果及促进大白菜生长的作用机理。结果表明 :经绿色植物生长调节剂处理后 ,发芽率增加 6 .4 % ,发芽势增加 6 .6 %。与对照相比 ,苗期茎尖过氧化物酶含量提高 2 9.8% ,根系脱氢酶含量提高6 5 .2 % ,根尖、茎尖激素含量都向正效应得到调控 ;受绿色植物生长调节剂的影响 ,田间营养生长旺盛 ,大白菜产量提高 6 .0 3% ,具有一定的应用效果。更多还原

【Abstract】 The experiments on application effect and action mechanism of ABT on Chinese cabbage were carried out, three trials (seed germination trial, seedling trial and field trial)were conducted. The results indicated that ABT6# has positive effect on content of internal hormone in stem apex and root of Chinese cabbage; the rate and potential of seed germination, peroxidase content in seedling stem apex, dehydrogenase content in seedling root and yield of Chinese cabbage treated with ABT6# increased up to 6.4%, 6.6%,29.8%, 65.2%, and 6.03% respectively as compared with control.更多还原
