| 摘 要： | 1988年,我们调查了生长在合肥地区的5个籼稻品种(早、中熟)和1个晚粳杂交组合的粒重和直链淀粉含量的变化过程.结果显示,籼稻品种的糙米和粳杂组合的千粒重分别在齐穗后26-32天和43天时达到最大值,而5个籼稻品种和粳杂的直链淀粉含量则分别在抽穗后22-24天和34天时达到的最高点.

RESEARH ON CHANGES OF GRAIN WEIGHT AND AMYLOSE CONTENT IN RICE DURING RIPENING PROCESS |
| |
| Abstract: | The change processes of the grain weight and amylose content of five
indica rice cultivars (early and medium) and a late japonica hyb
rid rice combination grown in Hefei were investigated in 1988. The
results showed that the 1000-grain weight of brown rice of indica cu-
ltivars and of japonica hybrid rice combination reached the maximum
during 26-32 days and 43 days after heading respectively, while
the amylose content of five indica cultivars and of japonica hybrd ri-
ce reached the highest point in 22-24 days and 34 days after headinig
respectively. |
