【摘要】 三角梅为全球热带、亚热带地区著名的木质藤本花卉，喜温、不耐寒的习性限制其在亚热带以北地区的绿化应用。基于三角梅地理分布及在中国的栽培应用概况，分别从耐寒品种筛选、适生性生态区划与栽培，以及种子播种驯化等方面总结其在上海耐寒适生性方面的研究与实践经验，并对未来三角梅耐寒驯化的对策及前景展开讨论：三角梅对0℃以上低温有一定的忍耐能力，低于-3℃会造成植株冻害死亡，冬季极端低温时应加强植株防护；选择耐寒性强的品种于背风向阳小气候立地种植，结合防风、保温辅助园艺措施以及种子播种循序抗寒锻炼等有助于提高三角梅抗寒力；为扩大三角梅栽培范围，耐寒品种选育将是未来方向。研究对于三角梅耐寒力提高、扩大栽培应用范围具有重要意义。更多还原

【Abstract】 Bougainvillea spp. is a famous woody vine flower in the tropical and subtropical areas of the world. Preference for hotness and not hardy to coldness limited its application in the north of the subtropical area. Geographical distribution and varieties cultivation in China were surveyed in this paper. From aspects of cold-tolerance varieties screening, temperature adaptable region division as well as seed-sowing domestication, the study and practice of Bougainvillea spp. in urban greening of Shanghai were summarized. Furthermore, the strategy and perspective of cold-tolerance domestication in future were discussed. Bougainvillea spp. has the ability to be tolerant to a low temperature above 0℃ to a certain extent. But exposing it to a low temperature below-3℃ would lead to dying out. The protective measure is necessary once extremely low temperatures come. Planting in a microclimate of leeward and sunny sites, a horticultural measure such as wind shelter and warm keeping and also seed-sowing domestication will be helpful for cold resistance. To expand cultivation, cold-resistance varieties breeding is still the future research objective. This paper is of great significance to increasing cold-tolerance adaptability and expanding of cultivation region to Bougainvillea spp.更多还原
