| 摘 要： | 在湖南长沙对油茶栽培品种新梢生长特性进行观测研究。结果表明:①油茶周年可抽新梢多次,对应四季萌发分为春、夏、秋、冬梢4种,它们的生长各具特点,其中:春梢旺盛,萌发量最多,夏梢生长期长,幼树常连续抽发2次夏梢,秋梢长势弱,冬梢少或无,春、夏梢是油茶幼树新梢的主体,是树体结构及产量的基础;②油茶新梢生长在不同林龄及品种间存在差异,它是鉴别品种及其早期丰产树型的条件之一,是树体调控以及栽培的理论基础和依据。

| Abstract: | The shooting growth characteristics of Camellia oleiferacultivars in Changsha,Hunan are observed.The results show that,① Shooting sprouts several times yearly as spring,summer,autumn and winter shooting according to the season.They have their own growth characteristics： The spring shooting are dominant,though the summer shooting are longer in growth period,and continuously sprout two times in young tree.The autumn shooting grows weaker.There are little or none of winter shooting in adult tree.Spring and summer shootings contribute the main body of the Camellia tree and yield.② There are differences in new shooting growth among cultivars and ages.It is one of the conditions of identifying early high yield tree for cultivars,and also is the theoretical basis and foundation for the tree structure control and cultivation. |
