板栗对板栗红蜘蛛和桃蛀螟的抗性机制初探

通过研究6个板栗品种叶片失绿指数、板栗红蜘蛛虫口密度、叶片形态特征和组织结构、桃蛀螟虫苞率、刺苞形态特征，发现不同板栗品种对板栗红蜘蛛和桃蛀螟的抗性存在差异，叶片上表皮厚度、下表皮绒毛密度、长度与抗螨相关性显著，叶片下表皮气孔密度、下表皮和海绵组织厚度与抗螨相关性较小；刺苞簇生率、刺苞体积与抗桃蛀螟相关性显著，刺苞底部厚度、苞柄长度、刺针的密度、长度与抗桃蛀螟相关性较小。

A preliminary study on the resistance mechanism of chestnut to Oligonychus ununguis(Jacobi) and Dichocrocis punctiferalis Guenee

To integrate management of pests and quality of fruits and breed high resistant variety,it is very useful to study the resistance of chestnut to Oligonychus ununguis(Jacobi) and Dichocrocis punctiferalis Guenee and its mechanism.The injury index of leaves,Oligonychus ununguis population density,morphological characters,structure of leaves,rate of bored shell by Dichocrocis punctiferalis Guenee,and morphological characters of shells are studied using 6 chestnut varieties.The results show that there are signi...
