| 摘 要： | 在不同光照梯度55.44%自然全光照(Natural sonlight,NS)、21.12%NS、3.47%NS 和0.86%NS的人工遮荫条件下,研究了侧柏(Platycladus orientalis)种子萌发的特点.结果表明:4个光照梯度处理的侧柏种子的萌发率分别为68.9%、82.2%、44.4%和42.2%;随着光照强度的减弱,种子萌发进程减慢;萌发指数和幼苗活力指数均在21.12%NS处理最大,分别为1.89和770.8.

| Abstract: | Under different light intensities,55.44% natural sunlight(NS),21.12% NS,3.47% NS and 0.86% NS in shade house,the characteristics of seed germination of L.obtusifolium were studied.The results showed that the final germination percentage under four shade treatments of different light intensities were 68.9%,82.2%,44.4% and 42.2% respectively.The course of germination was delayed with the decrease of light intensity,while both the germination index and vigor index peaked at the shade treatment of 21.12% NS was... |
