摘　　要：通过从云南收集的4个印度黄檀种源,分析了不同种源在肇庆地区的苗期生长表现。结果表明:4个种源的种子千粒质量均值变幅为27.3~31.4 g,发芽率高低依次为N00>y06>N02>y04,不同种源种子千粒质量与发芽率之间相关性不显著;4个种源苗木苗高和在6-9月生长最快,地径在3-6月生长最快;N00苗高生长量和地径生长量最大,苗期生长表现最佳,显著大于其他3个种源可初步作为优良的用材树种推广应用。This paper studied the seedling growth performance of different provenances in Zhaoqing City,and the 4 experimental Dalbergia sissoo species were collected from Yunnan.The results showed that the 1000-seed quality average value variation of four provenances ranged from 27.3~31.4 g,and the seed germination rate of four provenances ranked from high to low in order was N00,y06,N02,y04.There were no significant correlations between the thousand-seed quality and seed germination rate of different provenances;the sum of seedling height of four provenances grew fastest from June to September,and the ground diameter of four provenances grew fastest from March to June.The N00 had the greatest height growth rate and ground diameter growth rate,its seedling growth had the best performance which was significantly greater than other three provenances.In summary,N00 should initially be popularized and used as a good timber tree species.
