| 摘 要： | 通过野外实验，对雷竹无性系在不同光照强度下的生长进行了对比分析，结果表明，随着光照强度的降低，雷竹无性系分株数、分株高度、分株基径、无性系根茎总长度、分株根茎长度显著降低，而间隔子长度不断增加；在不同光照条件下，根茎节间长度和分枝角度没有显著变化；随着光照强度的降低，无性系单位长度根茎生物量下降。并对雷竹无性系根茎生长对光照强度的适应对策进行了讨论。

| Abstract: | Phyllostachys praecox cv. prevernalis is an excellent species for shoot. Analysis on growth of the bamboo clones with different light intensity resulted that along with the decrease of light intensity, the ramet amount per clone, height and basal diameter of ramet, total rhizome length of clone and rhizome length of ramet declined evidently, while length of space increased. Internode length and branching angle had no significant difference from different treatments. With the decrease of light intensity, rhizome biomass of clone and per unit length declined. Discussion was made on adaptability of Ph. praecox cv. prevernalis on light intensity. |
