对采自6省(区)37个木荷种源种子进行了苗期试验,结果表明,木荷种子千粒重、室内发芽率存在明显地理种源变异,木荷种源间苗高、地径、生物量有着极显著的生长差异,且有较高的广义遗传力。木荷苗高生长以8～9月份为速生期,这时期的生长占年生长的50%～56%,苗高和地径生长与纬度呈极显著负相关。说明,通过木荷种源选择,能取得较好的效果。并初步筛选出广东开平、阳山、韶关,福建华安,江西上犹等苗期生长表现突出的种源。
Seedlings of 37 seeds of Muskmelon seeds collected from 6 provinces (districts) were tested in seedling stage. The results showed that there were obvious geo-provenance variations in seed weight and germination rate of Schima superba seedlings. Seedling height, diameter, The amount has a very significant difference in growth, and has a higher generalized heritability. The growth of Schima superba was fast from August to September, the growth of which accounted for 50% ~ 56% of the annual growth. The growth of height and diameter had a very significant negative correlation with latitude. That, through the choice of wood seed germination, can achieve better results. And initially screened out Guangdong Kaiping, Yangshan, Shaoguan, Fujian Huaan, Jiangxi Utah and other seedling growth of outstanding provenance.
