攸县油茶具有果皮薄、含油率高、油质好、抗逆性强、适宜密植等特点,近年来各省纷纷引种。为进一步探讨其生物学特性,为育种、栽培工作提供科学依据,几年来我们对攸县油茶的胚胎学进行了比较系统的研究,现作初步报道。材料与方法试材为栽植在湖南省林科所的19年生攸县油茶(Camellia yuhsienensis)。1.采样与固定:于1980年9月25日-11月底、1981年9月28日-1982年3月,在花芽分化的不同时期,分期分批采集不同大小的花蕾,去掉外层苞片、萼片和部分花瓣(留下内层2-3片花瓣),放入卡氏液中固定12-24
Youxian Camellia with peel thin, high oil content, good oil, strong resistance, suitable for close planting and other characteristics, the provinces have introduced in recent years. In order to further explore its biological characteristics and provide a scientific basis for breeding and cultivation work, we conducted a systematic study on the embryology of Youxian Camellia in recent years. Materials and Methods The test material was a 19-year-old Camellia yuhsienensis planted in Linke Institute of Hunan Province. 1. Sampling and fixing: From September 25, 1980 to the end of November 1980, from September 28, 1981 to March 1982, flower buds of different sizes were collected in batches at different stages of flower bud differentiation, and the outer bracts were removed , Sepals and part of the petals (leaving the inner layer of 2-3 petals), placed in card fluid fixation 12-24
