二年生红花油茶嫁接苗生长规律初步研究

Preliminary Study on the Grafted Seedling Growth Rhythm of 2-year-old Camellia chekiangoleosa

通过对2年生红花油茶嫁接苗株高和地径生长特性的观察,结果表明:2年生红花油茶苗株高、地径生长分布表现为正态分布,苗木优势个体在早期已表现出遗传分化,1年中苗木株高在6月初和10月初、地径在6月中旬和10月中旬分别有一个生长高峰期,且存在线性关系,为苗木培育管理提供借鉴。

The growth characteristics of 2-year-old Camellia chekiangoleosa gratfted seedling, including height and basal diameter, was observed and analyzed. The results indicated that： The seedling growth of height and basal diameter showed the normal distribution; Seedlings in the early period had shown the advantage of individual genetic differentia- tion; The growth peak period of seedling height was in early June and October and that of the basal diameter was in mid- dle June and October, and there was the linear relationship between height and basal daimeter. All in all, it would pro- vide reference for seedling cultivation and management.
