| 摘 要： | 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：木荷种源间苗高、地径、生物量有着极显著的差异,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。 |

| Abstract: | The seedling provenances trial of Schima superba containing 37 seedlots collected from 6 provinces (zone) was conducted in Dexing, Anfu and Xinfeng,Jiangxi Province.The results showed there were very significant differences in seedling height, ground diamater and biomass of Schima superba provenances,and broad heritability of seedling traits were high.The seedling height growth of Schima superba provenances displayed quick growing period in August and September,height increment was more than 50% of total height increment.The seedling height and ground diamater were negatively related to latitude of the seedlots.5 quick-growing provenances were selected among seedlings, they are Kaiping, Yangshan,Shaoguan, Hua'an and Shangyou. |
