油茶由于落花落果严重,造成每年产量不高。近年来,良种选育工作已开始进行。为了选育良种,探讨落花落果的原因,了解开花和成果的关系,有着重要意义。油茶花的生物学研究是制订杂交方案的首要条件。掌握花期,找出适宜的授粉时间,在有性杂交上很重要。油茶花的习性、开花和结果方面的知识,对明确油茶品种优劣问题很有帮助。我们从1961年起,在抗病优株选择、鉴定和品种调查过程中,进行了油茶花期物候和 Camellia due to falling flowers serious, resulting in annual production is not high. In recent years, seed breeding has begun. In order to breed elite, to explore the reasons for falling, understand the relationship between flowering and fruit, is of great significance. The biology of camellia is the first condition for the development of hybridization programs. To master the flowering period, to find out the suitable pollination time is very important in the sexual cross. Camellia habits, flowering and the results of knowledge, to determine the advantages and disadvantages of Camellia varieties helpful. Since 1961, we conducted the Camellia flowering phenology and phenology in the process of disease resistance selection, identification and variety survey
