摘要：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 8.2 1%。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-southern provenances were significantly smaller than ones from eastern. The time of growth cease of southern provenances were slightly later. Huichang provenance had the best growth. As early fast growth of Choerospondias axillaris, density control in nursery become very important. Suitable nursery density for this speices is 1.08×10 5 seedlings per hectare.
