岑软2号、3号等油茶无性系的开花物候期观察

Flowering Phenophase Observation of Camellia oleifera Clones

对广西、湖南、江西、贵州4个省份的30个油茶优良品系,集中在广西岑溪市软枝油茶种子园进行大树嫁接换冠对比试验,对岑软2号、3号等30个油茶优良无性系的开花物候期(花期)的观测表明:除初花期外,引种自不同栽培区的油茶无性系的花期各动态时期均有显著的差异;各无性系的芽萌动期、花芽分化期、初花期、盛花期和末花期相互间亦呈极显著的相关。

Thirty oil tea superior clones from Guangxi, Hunan, Jiangxi, Guizhou provinces have been collected and canopy replacement contrastive tests have been set up in Cenxi City Soft-branch Oil Tea Seed Orchard in Guangxi. Observation of flowering phenophase of 30 oil tea superior clones such as Cenruan No. 2 and 3 and so on shows that, except the initial flowering phase, obvious variation exists in different dynamic phases of oil tea clones introduced from different planting areas; At the same time, notable correlation of sprouting period, flower bud differentiation period, initial flowering period, full flowering period and end flowering period of each clones are found.
