一种新型水稻生长调节剂对超级稻籽粒结实与品质特性的影响
Effects of A Kind of New-type Rice Growth Regulator on Grain Setting Traits and Quality of Super Rice
摘要
Abstract
Using super hybrid indica rice variety"Yangliangyou 6"and super middle japonica rice variety"Nanjing 45"as experimental materials,we sprayed a kind of new-type rice growth regulator prepared by us on the leaf surface of super rice at ini-tial heading stage,and studied the dry matter translocation,grain filling,yield traits,and rice quality characters of super rice. The results showed that:as compared with the blank control,spraying the rice growth regulator on leaf surface significantly in-creased the translocation rate of assimilative substance in rice stem,promoted the translocation of non-structural carbohydrates from stem and sheath to grains during grain filling,enhanced the grain setting rate,grain plumpness,1000-grain weight and grain number per spike of rice,and then significantly improved the theoretical grain yield of these two super rice varieties by 16.89% and 11.06%,respectively;the foliar application of this rice growth regulator also significantly reduced the chalky grain percentage and the rice grain chalkiness degree,lowered the amylose content in rice grains,and increased the content of crude protein in rice grains.关键词
