摘要：利用9个种源90个家系的无患子(Sapindus mukorossi)种子在浙江省杭州市余杭长乐林场进行苗期试验,结果表明,无患子1年生苗生长期可分为生长初期、速生期和木质化期,地径生长高峰期晚于苗高生长高峰期。方差分析表明,不同种源、不同生长时期苗高和地径生长性状差异较大,呈极显著水平。相关性分析显示,苗高生长性状与种源地纬度呈显著性负相关,南部种源苗期生长性状明显好于北部种源,初步选择出江西上犹、浙江龙泉、江西宜丰3个优良种源,上犹7号、上犹8号、上犹9号、宜丰1号、宜丰6号、龙泉4号和龙泉10号共计7个优良家系。
Sapindus mukorossi seeds from 9 natural provenances were used for seedling test in Changle Forest Farm of Yuhang, Zhejiang province. The results showed the growth period of 1-year seeding could be divided into three phases, initial growing period, fast growing period and lignifieadon period. Seedling height growth reached the peak earlier than ground diameter growth. Analysis of variance showed that both seedling height and ground diameter trait had great differences among different provenances and growth periods. Correlation analysis revealed that seedling height growth was negative with provenance latitude, indicating that seedling growth traits from the southern provenances were better than that from the northern ones. 3 superior provenances and 7 families were preliminarily selected, they were provenances of Shangyou and Yifeng of angx and Longquan of Zhejiang, families of Shangyou 7, 8 and 9, Yifeng 1 and 6, Longquan 4 and 10.
