摘　　要：用6-BA、IBA、GA 3等3种植物生长调节剂对降香黄檀种子进行萌发处理，测定降香黄檀种子中可溶性糖、淀粉、蛋白质和脂肪含量的变化。结果表明，降香黄檀种子在不同的萌发处理过程中，可溶性糖含量均呈下降趋势，萌发结束时淀粉含量由第3 d的0.6%下降至0.2%以下，其中6-BA处理后种子萌发前期（3～6 d）淀粉含量变化不大，后期则有一个显著的下降趋势；3种植物生长调节剂对降香黄檀种子蛋白质、脂肪含量变化影响不明显。Seeds of Dalbergia odorifera were treated by three plant growth regulators of 6-BA, IBA, GA 3 and distilled water. The content of soluble sugar, starch, protein and fat of seeds were determined during germination. The results showed as follows：seeds of D. odorifera showed a downward trend in the soluble sugar content in all treatments. The starch content dropped from 0.6%which was the one of the third day to 0.2% below when the seeds ended germination. In the early period of germination （3~6 d）, starch content of seeds changed little with the treatment of 6-BA, but there was a significant downward trend in the later period of germination. Changes of protein and fat content were relatively stable, and inapparent after treatment of three plant growth regulators.
