摘要:
通过对南京地区几个秋桂品种3 a花期物候的观察,比较了不同品种秋桂开花物候期及花芽和花部形态特点; 同时分析了秋桂开花物候期与气温的关系,认为在花芽完成分化并发育到某种程度之后,日最低气温降至启动低温是进入花期的关键,表现为圆珠期花芽迅速膨大,进入顶壳期; 顶壳期之后,对低温要求不严格。研究品种中‘早银桂’花期最早,随后‘早籽银桂’和‘雄黄桂’进入花期,‘晚银桂’、‘金球桂’、‘金狮桂’有大量花开的花期接近,均较迟。
Abstract:
Through three years observation of Nanjing area a few autumn sweet Osmanthus cultivars blooming season phenology,compared their blooming season phenology and the external morphological characteristics of the flower bud or flower. At the same time, analyzes of the relationship between phenology and temperature, think that after the completion of flower bud differentiation and development to some extent, and daily minimum temperature below critical temperature is the key to enter the florescence. That performance for the ball-shaped flower bud expansion immediately, and then enter to top bracts stage; during the stage of top bracts to blossom stage is not strict requirements on low temperature. In the six research cultivars, the florescence of Osmanthus fragrans ‘Zaoyingui’ is the earliest, then O. fragrans ‘Zaoziyin’ and O. fragrans ‘Xionghuang’ research florescence,the florescence of the large number of blossom of O. fragrans ‘Wanyingui’, O. fragrans ‘Jinqiugui’ and O. fragrans ‘Jinshi’ at the latest.
