摘要: 通过对4种透光度下黄山松苗及黄山松与麻栎混播苗连续3年生长、生理指标的定期观测,以及黄山松种子综合测试,探讨了黄山松种群在天然林下更新的机理.结果表明,黄山松种子饱满率65%,发芽率仅为27%,综合逆境活力为26%.较低的发芽率在一定程度上影响了黄山松的繁殖能力.黄山松光合速率受太阳辐射能的影响较大,而受湿度、地表温度影响较小.黄山松光补偿点高,从而导致其林下更新较为困难.由于黄山松苗生长缓慢,针阔混播区的黄山松苗因受光条件差而生长势较弱,从而处于竞争劣势.

Abstract: The growth and physiological characters of 1~3 years old Huangshan pine seedlings in pure and mixture plots with four different transparancy were determined,and the germination percentage of seeds and their complex stressing vigour were tested.Meanwhile,the regeneration mechanism of Huangshan pine in natural forest was studied in this paper.The results showed that the plumpness of seeds was 65%,the germination percentage was 27%,and the complex stressing vigour was 26%.The lower germination percentage affected the reproduction of Huangshan pine.The photosynthetic rate was more affected by solar energy,but less by humidity and surface temperature.With high light composation,Huangshan pine's regeneration under forest was difficult.The seedlings of Huangshan pine in mixed coniferous and broadleave tree plots were at a disadvantage because of slow growth and insufficient ligth.
