| 摘要: |
| 油茶 Camellia oleifera 幼苗的春季抽梢状况是油茶苗期营养生长调查的重要内容，也是判断
其在引种区适应性的主要依据之一。研究以广东、湖南、江西和广西主推普通油茶品种的芽苗砧嫁接幼
苗为研究对象，调查广州地区普通油茶嫁接幼苗的春梢生长发育，包括抽梢率、梢长和发育程度等指标。
对比分析发现，“岑软 3 号”、“华硕”、“岑软 2 号”和“湘林 XLC15 号”4 个普通油茶品种在抽梢率和平
均梢长方面具有较明显优势，且半木质化程度较低，在广州地区表现出了较强的适应性和早期快速营养
生长潜力。 |

| Abstract: |
| The vernal sprouting length and development of clonal sapling is the basic content of the
investigation of Camellia oleifera seedling stage growth and contributes to predicate adaptability in the
introduction area. We regarded the hypocotyle grafting seedlings of C. oleifera, which are recommended in
Guangdong, Hunan, Jiangxi, and Guangxi Provinces, as the research objects and studied the vernal sprouting
rate, shoot length, and ligni?cation degree. The comprehensive analysis showed that“ Cenruan 3”,“ Huashuo”,
“Cenruan 2”, and“ Xianglin XLC15”, with high vernal sprouting rate, long average shoot, and low degree of
semi-ligni?cation, represented salient adaptability and early rapid growth potential in Guangzhou. |
