<正>从枫香果实的含水量、粗脂肪含量、果实比重等方面来探讨枫香种子成熟的指标与成熟期。结果表明 :种子粗脂肪含量可作为枫香种子成熟的精确指标 ;枫香果实的含水量可预测枫香种子成熟期 ;果实比重及颜色的改变不能作为枫香种子成熟的精确指标 ;南京地区枫香种子于 1 0月上旬成熟

Maturation index and maturation of Liquidambar formosana seeds were studied based on moisture content and specific gravity of fruiting heads, crude fat content of seeds. The results showed that crude fat content of seeds is the accurate quantitative indication of Liquidambar formosana seed maturation, moisture content in fruiting heads also predicts the seed maturation, fruiting heads specific gravity and colour give no promise as a maturity index and Liquidambar formosana seeds mature in early October in Nanjing.
