【摘要】 对 1 6个果蔗品种的特征特性进行了初步研究 ,结果表明 :大部分果蔗品种是甘蔗属热带种 (SaccharumofficinarumL .) ,其株形直立 ,蔗茎粗大 ,体细胞染色体数为 2n=80 ,叶片酯酶同工酶的变异不大 ;少部分果蔗品种是杂交选育的品种。不同果蔗品种的出苗率、分蘖率、产量及品质有较大的差异。夏植“黑皮果蔗”的有效茎数及产量与下种量之间没有明显相关性。文末介绍了若干优良果蔗品种更多还原

【Abstract】 The characteristics of 16 chewing cane varieties were studied preliminarily,the results indicated that most chewing cane varieties derived from Saccharum officinarum and had erect plant type and thick stem,these varieties were diploid, and the number of chromosome in their somatic cells was 80, the variation of esterase isoenzyme in their leaves was not significant;few chewing cane varieties were bred by hybridization.The difference of rate of seedling emergence, rate of tiller, yield and quality among different chewing cane varieties was significant. So far as "Badila" planted in summer was concerned, the number of effective stem and yield were not markedly related to the sowing norm. Some superior chewing cane varieties were introduced in this paper.\;更多还原
