| 摘 要： | 对马尾松1、2年生苗木中松醇、肌醇、可溶性糖等小分子有机化合物进行动态监测。结果表明:1年生马尾松苗木针叶内松醇含量随着苗木的生长而逐渐增加,并在木质化期达到最高;2年生苗木针叶内松醇含量随着苗木生长反而下降,只在木质化期有所增加。肌醇、半乳糖和麦芽糖含量的变化较为复杂,均没有规律性。葡萄糖含量的变化比较平稳,2年生苗木在8月份时其葡萄糖含量明显高于1年生苗木的。

| Abstract: | With one-year-old and two-year-old Pinus massoniana seedlings as materials,the small molecular organic compounds such as pinitol,myo-inositol and soluble sugars were dynamically monitored. The results showed that,the pinitol content in the needles of one-year-old Pinus massoniana seedlings increased along with seedling growth,and reached the highest point in hardening phase. However,the pinitol content in the needles of two-year-old Pinus massoniana seedlings decreased along with seedling growth and only increased in hardening phase. The changes of the contents of myo-inositol,galactose and maltose were relatively complicated. The glucose content changed steadily,and the glucose content in the needles of two-year-old seedlings was much higher than that of one-year-old seedlings in August. |
