赣系列油茶无性系在闽西的生长结实表现

The growth trait and fruit yield of different Gan series Camellia oleifera clones planted in western Fujian

为筛选闽西适生的油茶高产品种,对当地引种的10个赣系列油茶无性系生长和产量表现进行了连续3a的调查测定。结果表明:不同赣系列油茶无性系的树高和冠幅产量存在显著差异,其中赣8和赣无2无性系的产量较高,3a平均冠幅产果分别为2.62 kg·m^(-2)和3.33 kg·m^(-2);不同无性系年均产油由高到低表现为:赣8>赣无2>赣石84-3>赣447>赣55>赣永6>赣190>赣无1>赣68>赣71,其中,赣8 (697.12 kg·hm^(-2))和赣无2 (626.25 kg·hm^(-2))的产油量超过油茶优良无性系选育标准值(450kg·hm^(-2)),适宜在闽西山地推广栽植。

In order to screen high-yielding Camellia oleifera varieties suitable for planting in western Fujian, the growth performance and fruit yield of 10 different Gan-series C. oleifera clones were investigated and observed for 3 consecutive years in local. The results showed that the tree height and fruit yield in unit crown area are of great difference between different clones. The yield of Gan 8 and Ganwu 2 were the highest two among 10 clones, of which the average annual fruit yield and fruit yield in unit crown area in 3 years reached 2.62kg·m^(-2)and 3.33 k·gm^(-2), respectively. The average annual oil yield of different clones from high to low was as follows: Gan 8 > Ganwu 2 > Ganshi 84 3 > Gan 447 > Gan 55> Ganyong 6 > Gan 190 > Ganwu 1 > Gan 68 > Gan 71. Among them, the oil yield of Gan 8 and Ganwu 2 reached 697.12 kg·hm^(-2)and 626.25kg·hm^(-2), respectively, which far exceeded the standard value of C. oleifera superior clone(450 kg·hm^(-2)) and were appropriate clones for popularizing and planting in western Fujian.
