籽粒满为近几年来国内研制和开发的植物生长物质,主要成分为细胞分裂素。如众所周知,细胞分裂素能有效地阻滞叶片的衰老。为此,我们在冬小麦扬花期喷施籽粒满,观察对小麦的影响。结果如下: 叶绿素和类胡萝卜素含量 1994年5月9日在小麦扬花期,我们用10×10~(-6)籽粒满水溶液对小麦植株进行喷施,在喷施处理后的第3天、7天、21天和28天时,分别对小麦旗叶的叶绿素和类胡萝卜素的含量进行了测定。结果表 Grains full for the past few years, domestic research and development of plant growth substances, the main component of cytokinin. As we all know, cytokinin can effectively block leaf senescence. To this end, we sprayed the grains at the flowering stage of winter wheat to observe the effect on wheat. The results are as follows: Chlorophyll and carotenoid content At the wheat flowering stage on May 9, 1994, wheat plants were sprayed with 10 × 10 -6 grain water, and on the third day after spraying, The contents of chlorophyll and carotenoid in wheat flag leaf were measured at 7, 21 and 28 days respectively.
