摘　　要：对黄檗6个家系幼树进行盆栽遮光试验,研究光照强度对黄檗家系幼龄期生长的影响.结果表明:轻度遮光有利于黄檗幼树生长,光照强度很弱时黄檗生长受到抑制;同一光照条件下,不同黄檗家系间生长量差异达到极显著水平,家系H14-2-3树高和地径生长量最大,显著高于其他家系,家系H17-9-5树高和地径生长量较小;不同光照强度间黄檗家系生长量差异显著,黄檗幼树生长量因光照强度减弱而降低,H1-11-22和L18-2-112家系在光照强度变弱时,生长量下降幅度较小,H14-2-3和H20-6-17家系生长量下降幅度较大.Potted shading experiment was carried out to study the effect of light intensity on the 6 families sapling of Phellodendron amurense Rupr.The results showed that it was beneficial to the growth of Phellodendron amurense saplings when the light intensity decreased slightly,and the growth was inhibited when the light intensity was weak.There were greatly significant differences of growth amount among families of Phellodendron amurense Rupr.under the same light condition.The growth amount of height and diameter of H14-2-3 was the biggest,and significantly bigger than others.The height and diameter growth of the family H17-9-5 were small.There was significant difference in growth of Phellodendron amurense Rupr family.under different light intensities.The growth of sapling of Phellodendron amurense Rupr.decreased with the decrease of light intensity.When the light intensity decreased,the growth amount of H1-11-22 and L18-2-112 families decreased little,and the growth of H14-2-3 and H20-6-17 families decreased greatly.
