Abstract: The habits of pollination and flowering, and artificial methods of Bougainvillea hybridization were carried out in this study. Optimal observation times of collecting pollen and pollination were obtained, which were tepals micro cracking of 1~2 mm and flower beginning to open within 2 d; as well as a suit of artificial pollination technology in Bougainvillea. The highest seed set ratio of 8.3% was observed after artificial hybridization in Bougainvillea.

Key words: Bougainvillea, artificial pollination, seed set ratio

摘要： 本文研究三角梅开花时花器的变化规律及三角梅的杂交授粉技术。通过对不同时期花器的观察对比，发现三角梅的最佳花粉采集时间为花被片微开裂1～2 mm，最佳授粉时间为花初开2 d内；通过人工杂交授粉试验，摸索出三角梅杂交授粉技术。杂交试验表明，伊娃夫人与帝国喜悦的杂交结实率最高，可达8.3%。
