中文摘要:
      【目的】筛选适合广东地区亚热带环境条件下生长良好且具有较高观赏应用价值的中小株型卡特 兰新优品种。【方法】以 14 个引进的卡特兰属种质为试材,在广州开展适应性栽培管理与比较筛选。通过连续 多年的观察、性状测定和统计分析,系统评价不同种质的田间生长特性、观赏品质性状及抗性特点。【结果】 11 个候选种质在广东地区都有一定的适应性,较适合在广东地区栽培应用。其中筛选出的 I 级和 II 级种质,植 株生长性更好、抗性更强、成花较容易、观赏价值较高,建议向市场推荐进行景观美化使用。【结论】从 14 个 种质中优选出的 I 级种质卡特兰‘豹王’(C-3)、卡特兰‘金孔雀’(C-12)和卡特兰‘四季樱花’(C-14) 3 个杂交园艺品种,可作为适于广东地区栽培应用的优先推荐发展品种,建议对这些优势品种开展优先栽培生产 和主导示范应用。同时对于其他非优势种质,根据育种需求作为种质资源进行保存。
英文摘要:
      【Objective】The research was conducted to screen out new and desirable varieties of medium-smallsized Cattleya germplasm that grow well under subtropical environmental conditions and show high ornamental values in Guangdong Province.【Method】Fourteen introduced Cattleya germplasm were used as experimental materials and adaptive cultivation management and comparative screening were conducted in Guangzhou. The field growth characteristics of different germplasms, ornamental quality traits and resistance characteristics were evaluated systematically through continuous years of observation, characters measurement and statistical analysis.【Result】The statistical results of various indicators show that the 11 candidate germplasms have good adaptability in Guangdong and are more suitable for cultivation and application in Guangdong area. Among them, the grade I and grade II germplasms screened out have better plant growth performance, stronger resistance, easier flowering capacity and higher ornamental value, which are worth recommending to the market for landscaping germplasms.【Conclusion】Through comprehensive evaluation, three hybrid horticultural varieties of grade I germplasm are selected from 14 candidate germplasms, namely Cattleya Vigour Leopard King(C-3), Procatavola[Pcv.]Golden Peacock(C-12)and Brassolaelia[Bl.]Suzette Chaney(C-14). And these three selected varieties can be used as preferred varieties for cultivation and application in Guangdong. It is recommended that these dominant varieties should be given priority in cultivation, production and leading demonstration applications. At the same time, for other non-dominant germplasms, they can be used as germplasm resources for material preservation according to breeding needs.
