摘要
对6个陆地棉品种(系)单株的产量分布进行了分析.表明,各品种第一果位铃产量极大程度地决定了单株产量,第一果位的不同节位间皮棉总重、总铃数均存在极显著差异,而单铃重、衣分在节位间的变异因品种有所不同.不同品种其结铃峰值及其上下节位产量对单株产量起重要作用,结铃峰值节位的高低因品种而异.
Space distribution of single plant yield characteristicswere analysed. The result showed that the yield of every varieties (strains) was mainly decided by the yield of bolls on the first stemnode; and that the ginned cotton weight and the total numbers of thebolls a-mong different stem node were significantly different, whilethat the variations of each boll weight and lint percentage weredifferent from different species; and that the peak value of bearingbolls and the yield of up-down stem nodes played important roles in theyield of each single cotton; and that the peak value and how high thestem nodes located were also different from different species.
