| 摘 要： | 以吉林省1958-2005年间育成的33个水稻品种为材料,研究了产量、收获指数及植株地上部分各器官生物量的变化。随着品种的遗传改良,产量、收获指数、有效分蘖生物量和单茎生物量增加,分蘖总数减少。47年间产量由9118·36kg/hm2增加到15060·1kg/hm2,收获指数由0·46增加到0·55,平均每年分别增加1·39%和0·44%。随着品种的演替,单株分蘖总数下降,收获期单位土地面积生物量略有增加。产量和收获指数的增加是有效分蘖生物量和单茎生物量增加的结果。品种改良过程中单茎生物量增加是植株各器官生物量增加的结果,其中,抽穗期茎鞘生物量和抽穗后30d叶片生物量分别增加75·17%和49·94%。抽穗后叶片生物量和抽穗后10d的茎鞘生物量与产量呈显著相关,可作为高产品种的选择指标;抽穗后30d的单茎生物量与产量呈显著相关。

| Abstract: | In order to understand the changes in yield, harvest index (HI) and biomass of above-ground parts of rice, 33 japonica rice cultivars released from 1958 to 2005 were planted. During the 47 years, the grain yield increased from 9 118.36 to 15 060.1 kg/hm2 and HI from 0.46 to 0.55 in the genetic improvement of rice, with the average annual growth rates of 1.39% and 0.44%, respectively. In the genetic improvement, the total number of tillers per plant decreased, and the biomass per unit area slightly increased... |
