摘　　要：植物生长促进剂ＷＤ－５和ＷＤ－９于苗期或苗、苔期各喷施１５０ｍｇ／ｋｇ，其叶面积增大，干物质量增加，光合强度增强；苗期喷施者的ＧＡｓ和ＩＡＡ含量分别比对照高３７．４％～６１８．２％和３８．２％～１１４．４％，但ＡＢＡ含量也比对照高，因而易产生早衰现象．ＷＤ－５苗期喷施增产１０．２％，苗、苔期各喷一次增产１４．７％；ＷＤ－９苗期喷施增产１３．１％，苗、苔期各喷一次增产９．０％．Physiological and yielding efficacy of applying plant growth promoter WD 5 and WD 9 on rapeseed at seedling and stem elongating stages was studied.The results showed that spraying WD 5 and WD 9 at 150 mg/kg in seedling stage gave increase in leaf area,dry weight,photosynthetic rate,endogenous gibberellic acids (GAS),indoleacetic acid (IAA) and abscissic acid (ABA),but reduce in chlorophyll content and ascorbic acid content (Vc).When WD 5 was applied at seedling stage and at both seedling and stem elongating stages,the seed yields were increased by 10.2% and 14.7%,while WD 9 was applied at the same stages above mentioned,the seed yields were increased by 13.1% and 9.0%,respectively.
