摘　　要：用14CO2示踪的方法研究冬小麦籽粒灌浆期在穗部施用植物生长调节剂,对小麦产量形成的影响。结果表明,脱落酸(ABA)和赤霉酸(GA3)对灌浆冬小麦源库之间以及同化物的运输和分配有着调控作用。ABA的施用对冬小麦籽粒灌浆期,14C同化物运输和分配起阻碍作用,而GA3则起促进作用。Taking relationship, translocation and distribution of photosynthesis assimilates as indexes, the adjustment of plant growth regulator in source-sink was investigated by ^(14)C-tracer technique during grain filling of winter wheat. The results show that the application of ABA and GA_3 affect the translocation and distribution of the ^(14)C-assimilates. Application of ABA inhibits and GA_3 stimulats effect on the translocation and distribution of ^(14)C-assimilates.
