| 摘 要： | １９８９～１９９３年连续５年在福州研究了４３个甘蔗品种叶色、叶冠姿态、株高、叶面粗糙程度、＋３叶长和宽、＋３叶面积、＋３叶着生角度等形态特征与抗绵蚜的关系。结果表明．叶色深浅与感蚜性有极显著的正相关，但随绵蚜的发展而逐渐减小并在高峰期消失；＋３叶宽始终与感蚜性呈极显著或显著的正相关．宽大的叶片有利于绵蚜的发生和发展；叶面粗糙程度在绵蚜发生中后期与感蚜性有极显著或显著的负相关，粗糙的叶面有限制绵蚜扩展的作用。

| Abstract: | in 1989-1993,the relationships between&morpholosical characters and resistance to Ceratovaouna lanignera Z.of 43 foreign sugarcane varieties were studied for 5 years in Fuzhou.The results showed that the leaf colour was high-significantly and positively correlated with the aphid indices,but this correlation significances decreased with the development of the aphids and became negligible at the peak time of the aphid density;+3 leaf width was high-significantly or significantly and positively correlated with the aphid indices st all periods,wide leaves were benificial to the intrusion and development of the aphids; the roughness of leaf surface was high-significantly or significantly and negatively correlated with the aphid indices in the middle and later stages of the aphids,rough surface of leaf had a restraining effect on spread of the aphids. |
