The field trials showed that the control efficacy of 33.5% oxine-copper SC against leaf spot disease on waxberry reached above 74% when used at the dosage of 167.5-223.3 mg/kg. 33.5% Oxine-copper SC could be used to control leaf spot disease on waxberry.展开更多

[ Method] Eighteen waxberry cultivars （lines） in Jiangsu Province were analyzed using ISSR-PCR method, and molecular phylogenetic tree was constructed using UPGNA method. [ Result ~ A total of 70 DNA fragments were amplified with nine screened primers, including 43 polymorphic fragments, accounting for 61.4% of the total number of amplified fragments; 18 waxberry cultivars （lines） were clustered into 6 categories with the genetic distance of 0. 14, indicating that there is partial isolation on the basis of gene exchange between waxberry cultivars （lines） in Jiangsu Province. [ Conclusion] This study provided scientific basis for the protection and utilization of waxberry germplasm resources and cultivation of new varieties.展开更多
