【摘要】 应用灰色系统理论的关联度分析法探讨甘薯主要性状对淀粉产量的影响程度。结果表明,甘薯主要性状与淀粉产量之间的关联度依次为:烘干率>中薯率>鲜薯产量>成薯率>分枝数>蔓长>蔓粗>大薯率。更多还原

【Abstract】 The relationship among each traits of yield was researched with the relevance analysis of gray system.The result showed that the relevanty degree of each traits with starch yield was that the drying material rate was the largest contribution to starch yield,then the order from big to small was: the midding root rate,the yield of fresh root,the big and middle root number,the number of branch,the vine length,the stem diameter and the rate of big root.更多还原
