枣树叶片结构与抗蓟马危害的适应性分析
Adaptive analysis of leaf structure and thrips resistance in jujube trees
摘要
Abstract
Thrips are one of the most serious pest insects in current jujube tree production.The correlation between leaf structure and thrips damage was analyzed to clarify the thrips resistance mechanism in jujube cultivars.Three jujube cultivars,'Huping jujube''Lengbaiyu'and'Liuyuexian'were used as experimental materials.During different phenological periods,the thrips population density per plant was investigated using blue sticky traps,and the leaf damage rate was determined by random sampling.Then,the morphological characteristics,stomatal structure and anatomical structure of the leaves were determined by the combination of leaf area meter,scanning electron microscopy and paraffin sectioning method.Finally,the correlations between the leaf structure characteristics and the leaf damage rate as well as population density per plant of different jujube cultivars were analyzed.The results showed that there were significant differences in the thrips population density per plant and leaf damage rate among three cultivars(P＜0.05).'Huping jujube'had the lowest thrips density but the most serious damage,while'Lengbaiyu'and'Liuyucxian'had higher thrips density but lighter damage.The wax content of the upper leaf epidermis was highest in'Huping jujube',followed by'Lengbaiyu'and'Liuyuexian'.There was a positive correlation between stomatal density and population density per plant,while a negative correlations were observed between palisade tissue thickness,leaf thickness and population density per plant.In addition,leaf water content,stomatal aperture,epidermal thickness and leaf thickness affect the leaf damage rate.关键词
