Resistance Identification of Different Citrus Cultivars against Huanglongbing
摘要
Abstract
In order to find out which citrus cultivar is highly susceptible /resistant to citrus huanglongbing ( HLB) ,and then to use them for the research of compatible/incompatible interaction between citrus and Can-didatus liberibacter asiaticus ( CLas) ,this study tested the HLB resistance of three citrus cultivars of Citrus re-ticulata Blanco cv.ponkan,Citrus grandis ( L.) Osbeck cv.guanximiyou,and Citrus unshiu Marc.The experi-mental steps included:1.Screening out Citrus tree which carried CLas , but did not carry phytoplasma , Citrus tristeza virus,and other pathogens;2.Grafting above three cultivars using buds of the citrus tree;3.Observing symptom changes and detecting CLas of all the grafted trees at particular time .The results showed that in pon-kan mottle and yellow leaves appeared and CLas was detected three months after grafting ,and eight months af-ter grafting,all leaves fell and the tree died.As to guanximiyou,only slight mottle symptom appeared on young leaves and CLas was detected four months after grafting ,and eight months after grafting the tree still kept grow-ing normally.However,for Citrus unshiu Marc.,the plants still had normal appearance and CLas was detected eight months after grafting .Based on the experiment ,it was concluded that to HLB ,ponkan was highly suscepti-ble,Citrus unshiu Marc was highly resistant ,and guanximiyou had some extent of tolerance .关键词
