天达-2116对冬小麦后期物质转运及产量的影响

Effect of Tianda-2116 on Matter Distribution and Yield of Winter Wheat

试验表明，植物生长调节剂天达-2116对冬小麦后期物质转运及产量有一定的调控效应。主要表现为：提高千物质积累量和花前物质向籽粒的运转量，增加了小麦灌浆物质的潜在源；籽粒饱满指数增加，改善穗部性状；提高产量，增产幅度为1．50％～7．50％。

The results of field experiment showed that Tianda- 2116 increased the amount and transporting percentage of dry matter accumulated before flower to the grain, made the seed more plump and finally increased grain yield by 1.50% - 7.50%.
