以南方6个省8个地点的种子为试材,研究发现南酸枣在种子形态、种子大小、苗期生长节律和造林初期生长量上均存在种源差异.西部种源种子明显小于东部种源,偏南部种源的苗木生长停止期较迟,江西会昌种源生长最佳,其2年生幼林树高和胸径生长量超过试验群体平均值的11.75%和8.21%.南酸枣幼年期生长迅速,在优良圃地条件下育苗密度不宜超过每公顷10.8万株.

The Choerospondias axillaris seeds from 8 locations ranging 6 provinces in southern China were studied . Seed size, form, collar, seedling height growth rhythm and growth 2 year after planting showed obvious differences among provenances. The seeds from west-sou t hern provenances were significantly smaller than ones from eastern. The time of growth cease of southern provenances were slightly later. Huichang provenance ha d the best growth. As early fast growth of Choerospondias axillaris, density control in nursery become very important. Suitable nursery density for this speices is 1.08×105 seedlings per hectare.
