| 摘 要： | “AB型增粒剂”应用于杂交稻制种、繁殖，能够显著改善不育系的异交性能，提高异交结实率和产量。该剂应用后对于减轻不育系包颈、调节穗层结构、提早花时，提高柱头外露率以及柱头生活力等方面具有特殊功效。根据多年来各地制、繁种生产上研究和应用结果，一般可提高异交结实率20％-30％，增产20％-25％。

| Abstract: | AB grain-increasing agent", applied in hybrid rice seed production and multiplication, can remarkably improve the outcrossing characteristic of CMS line and increase the outcrossing rate and yield. This agent has special functions for reduce the basal part of panicle in the flag leaf of female parent,adjust the panicle layer structure,bloom early,increase the stigma exsertion rate and vitality. According to the result of our research and appling in hybrid rice seed production and multiplication for years, we can get higher outcrossing rate 20-30 percent and higher yield 20-25 percent. |
