摘要: 以田间虫口密度、网室内单位叶面积产卵量和世代存活率为指标测定了12份茶树种质对黑刺粉虱的抗虫性,并对叶片组织结构与网室内单位叶面积产卵量和世代存活率分别进行相关性分析。结果表明:优510、优3、丹桂、玉龙和九龙袍对黑刺粉虱的抗虫性较强,而G31、白鸡冠、福云10号和铁观音的抗虫性较弱。黑刺粉虱产卵量与气孔密度呈显著正相关(R=0.7950),与海绵组织厚度呈显著正相关(R=0.6790),而与栅栏组织厚度呈显著负相关(R=-0.7187,),与下表皮角质层厚度有接近显著水平的负相关(R=-0.6439);黑刺粉虱的世代存活率与气孔密度有接近显著的正相关(R=0.6654),而与下表皮厚度有极显著负相关(R=-0.8390),与下表皮角质层厚度有显著负相关(R=-0.7843),与栅栏组织厚度有极显著负相关(R=-0.8109)。

Abstract: Using field pest density and the number of oviposition per unit area and the generational survival rate of A. spiniferus in laboratory as indexes, the resistance of 12 tea germplasm to A. spiniferus was studied. Relationships between leaf structure of 9 tea germplasms and the oviposition numbers of A. spiniferus and its generational survival rate were analyzed. The results showed that the resistance of You 510, You 3, Dangui, Yulong, Jiulongpao to A. spiniferus was stronger than that of G31, Baijiguan, Fuyun No.10 and Tieguanyin. The oviposition numbers of A. spiniferus was found to have significantly positive correlation with stoma density(R=0.7950, F=12.0267, P=0.0104) and thickness of spongy tissue(R=0.6790, F=5.9890, P<0.05), have significantly negative correlation with thickness of palisade tissue(R=-0.7187, F=7.4784, P<0.05) and nearly significantly negative correlation with thickness of cuticular layer on subepidermis(R=-0.6439, F=4.9591, P=0.0613). Meanwhile, the generational survival rate of A. spiniferus have nearly remarkably positive correlation with stoma density(R=0.6654, F=5.5605, P=0.0505), but extremely-marked negative correlation with thickness of subepidermis(R=-0.8390, F=16.6361, P<0.01), and extremely-marked negative correlation with cuticular layer on subepidermis(R=-0.7843, F=11.1886, P=0.0123), and extremely-marked negative correlation with thickness of palisade tissue(R=-0.8109, F=13.4414, P<0.01).
