【摘要】 为了探索苏丹草种皮不同色泽类型间种子产量差异,试验以奇台苏丹草(Sorghum sudanense cv.Qitai)种子的黑壳、红壳、黄壳3种色泽类型为材料,研究了生育期、形态及种子产量构成等指标。结果表明,黑壳生产的种子的千粒重最大,红壳次之,黄壳最低,分别为14.66、13.36和12.77 g。黑壳的单株籽粒数最多,黄壳次之,红壳最低,分别为1 319、1 217和908粒。黑壳的单株种子产量最高、黄壳次之、红壳最低,分别为18.59、16.29和14.65 g。黑壳产量最高,红壳次之,黄壳最低,分别为3 593.522、654.89和2 649.60 kg/hm2。更多还原

【Abstract】 In order to explore the influence of different seed coat color(black,red and yellow)on seed yield,the period of procreation,seed morphology and seed yield structure of Sudan grass(Sorghum sudanense cv.Qitai) were analyzed in the study.The results of this study showed that the weight of one thousand seeds with black,red and yellow theca were 14.66,13.36 and 12.77 g(black>red>yellow);the seed numbers of single tassel seed with black,yellow and red theca were 1 319,1 217 and 908 pills(black>yellow>red);the single tassel seed yield with black,yellow and red theca was 18.59,16.29 and 14.65 g(black>yellow>red);and the total yield of seeds with black,red and yellow were 3 593.52,2 654.89 and 2 649.60 kg/ha(black>red>yellow),respectively.更多还原
