本文研究了优质稻双竹粘和杂交稻威优64的物质生产与产量因子的关系,得到如下主要结果:(1)每亩穗数与分化前的物质生产量密切相关,每穗粒数与分化—齐穗期的物质生产量密切相关。(2)结实率与每颖花的灌浆量呈正相关,但是双竹粘的结实率可能主要取决于每颖花齐穗后生产的灌浆量,威优64则可能主要取决于每颖花齐穗前运转的灌浆量。(3)双竹粘的千粒重主要取决于颖花的容量,而威优64主要取决于灌浆程度.
In this paper, we studied the relationship between material production and yield factors of high quality rice double sticky bamboo and hybrid rice Weiyou 64. The main results are as follows: (1) The number of panicles per acre was closely related to the material yield before differentiation, Differentiation - full heading of material production is closely related. (2) Seed setting rate was positively correlated with grain filling per spike, but the seed setting rate of Rhizoma biscuits may depend mainly on the amount of grain filling produced after full spike per spike, while Weiyou 64 may be mainly determined by full spike The amount of grouting before running. (3) The weight of bamboo sticks depends mainly on the capacity of the spikelets, while Weiyou 64 mainly depends on the degree of filling.
