摘要
以流苏和青榨槭(均引自清西陵林场)2种植物的2 a生幼树为试验材料,研究了不同遮光度处理〔0(全光照,CK)、15%、35%、50%和70%〕对流苏和青榨槭生长情况以及叶片解剖结构的影响。结果表明:流苏在35%遮光条件下新梢生长量相对较高,茎增粗最大,叶片厚度、栅栏组织厚度和上表皮厚度均最大;青榨槭在50%遮光条件下生物生长量最大,叶片厚度、海绵组织厚度、上表皮厚度和下表皮厚度均最大。
Taking 2 years old seedlings of Chionanthus retusus and Acer davidii from the Westem Qing Tombs forest farm as test materials, the effects of different shading degree treatments 〔0 (full sunlight, CK), 15%, 35%, 50% and 70%〕 on the growth and leaf anatomical structure were studied.The results showed that the Chionanthu s retusus growth of new shoots was relatively higher, growth of stem diameter was the highest, the thickness of leaves, palisade tissue and upper epidermis were all largest on 35% shading condition.Acer davidii biological growth was highest, and the thickness of leaves, spongy tissue, upper epidermis and lower epidermis were all maximum on 50% shading condition.
