| 摘 要： | 研究了不同林分郁闭度对半夏地上部生长性状、块茎形态性状、叶片形态性状和生物量及其分配等方面的影响。结果表明:林分郁闭度对半夏株高、茎基径的生长的影响均达到了极显著水平,且半夏株高随着林分郁闭度的增大而增大;当林分郁闭度为0.5时,半夏块茎长、块茎宽、块茎高,以及单株总鲜重、单株叶鲜重、单株茎鲜重、单株块茎鲜重、单株总干重、单株叶干重、单株茎干重和单株块茎干重均达到最大值;在不同的林分郁闭度下,半夏生物量向叶、茎和块茎传输的分配趋势并不一致。

| Abstract: | The growth traits of up-ground part, tuber morphological traits, leaf morphological traits and the biomass and its allocation of Pinellia ternata (Thunb.)Breit. were studied by being treated with different canopy density. The results showed there were highly significant difference on height, stem diameter of P. ternata under different canopy density, and the height increased with the increase of canopy density. In the canopy density was 0.5, the tuber length, tuber width, tuber height, whole fresh weight, leaf fresh weight, stem fresh weight, tuber fresh weight, whole dry weight, leaf dry weight, stem dry weight and tuber dry weight were all reached the maximum. Under different canopy density, the allocation trend of the biomass to leaf, stem and tuber of P. ternata showed discordance. |
