以培杂泰丰和华优86为材料,研究了自主研制的米质改良剂对超级稻源库的调节和对稻米品质的效应。结果表明,米质改良剂降低了超级稻生长后期剑叶叶绿素含量和POD活性的下降幅度,延缓了水稻叶片的衰老进程;虽然米质改良剂对超级稻的库容无显著影响,但提高了库容的有效充实度,喷施米质改良剂后,两个超级稻品种的结实率和产量均显著提高;喷施米质改良剂后,培杂泰丰和华优86的垩白粒率和垩白度显著下降,外观品质得到显著改善。
In this study, we used the cultivar Taifeng and Huayou 86 as materials to study the regulation of super rice source bank and its effect on rice quality by self-developed rice quality improver. The results showed that the rice quality improver reduced the decline of flag leaf chlorophyll content and POD activity and delayed the senescence of rice leaves. Although rice quality improver had no significant effect on the storage capacity of super rice, but increased the storage capacity The results showed that the seed setting rate and yield of two super rice cultivars increased significantly after sprayed rice quality improver. After spraying rice quality improver, Whiteness decreased significantly, the appearance of quality has been significantly improved.
