摘　　要：对来自广东从化石门、东莞银屏山、台山北峰山的3个红花荷种源早期生长进行研究,结果表明,红花荷种源间的种子千粒重差异不显著,而家系间的种子千粒重差异极显著,种子千粒重与各个生长性状以及各个生长性状间均表现为正相关关系;从化石门种源的种子千粒重、苗高、幼林地径、树高和冠幅均最大。The early growth performance of three provenances of Rhodoleia championii Hook.F.from Conghuashimen Dongguanyinpingshan Taishanbeifengshan Guangdong province were studied.The results showed that there were no significant difference in thousand-seed weight among provenances,however there were highly significant difference in thousand-seed weight among families.There were positive correlation either between the thousand-seed weigh and every growth traits or every growth traits.The provenances from Conghuashimen had the maximum value in thousand-seed weigh,seedling height,tree height,diameter at breast height(DBH)and crown width of young forest.
