| 摘要: |
| 对 2015 年营建于广东省韶关市曲江区国有小坑林场的广东油茶 Camellia oleifera 种质资源林开展生长、开花结实调查。结果表明：5 种油茶中，树体大小（树高 × 冠幅）依次为：香花油茶 C.osmantha ＞高州油茶 C. gauchowensis ＞香花糙果 C. suaveolens ＞普通油茶 C. oleifera ＞小果油茶 C.meiocarpa，平均结果量大小依次为：香花油茶＞普通油茶＞高州油茶＞小果油茶＞香花糙果；平均花芽量大小依次为：小果油茶＞高州油茶＞普通油茶＞香花油茶＞香花糙果；平均花期从早到晚依次为：香花糙果＞小果油茶＞普通油茶＞高州油茶＞香花油茶。在高州油茶的 162 个无性系中，结果量较大（果实数量＞ 100 个）的无性系共有 30 个，树形基本以中间型为主，花期以偏晚到偏早之间为主，盛花期在12 月。 |

| Abstract: |
| A survey of the growth, flowering and fruiting of the Camellia oleifera germplasm resource forest in Guangdong established in the state-owned Xiaokeng Forest Farm in Qujiang district, Shaoguan City, Guangdong province in 2015 was carried out. The results showed that among the 5 oil-tea tree species, thetree body size (tree height*crown width) was as follows: C. osmantha> C. gauchowensis> C. suaveolens>C.oleifera> C. meiocarpa, and the order of average results was as follows: C. osmantha> C. oleifera> C.gauchowensis> C. meiocarpa> C. suaveolens; the order of the average flower bud size was: C. meiocarpa> C. gauchowensis> C. oleifera> C. osmantha > C. suaveolens; the average flowering period from morning to night was: C. suaveolens>C. meiocarpa>C. oleifera>C. gauchowensis> C. osmantha. Among the 162 clones of C. gauchowensis, there were 30 clones with a larger amount of fruit(the number of fruits>100). The tree shape was basically intermediate, the flowering period was mainly late to early, and the full flowering period was in December. |
