不同作物植株的生长和产量潜力都取决於苗势(Ross 等,1972;Grabe,1973;Chhina 等,1982)。然而苗势对所产生的种子质量的影响却没有可资利用的资料。因而进行了高粱苗势和籽粒产量及种子营养品质关系的研究。1983年雨季,53个基因型的种子(5个雄性不育系、8个纯合雄性亲本和40个杂交种)种在两次重复的随机区组设计小区里,一次重复灌溉(仅播后15天灌溉一次),而另一次重 Growth and yield potential of different crop plants depend on seedling potential (Ross et al., 1972; Grabe, 1973; Chhina et al., 1982). However, the effect of seedling on the quality of seeds produced does not have any information available. Therefore, the relationship between sorghum seedling vigor and grain yield and seed nutritional quality was studied. In the 1983 rainy season, 53 genotype seeds (5 male sterile lines, 8 homozygous male parents and 40 hybrids) were planted in two replicate randomized block design plots with one irrigation repetition 15 days irrigation time), while the other heavy
