【摘要】 用8种源植物及杉木枝叶不同浓度水浸液和清水浇灌盆栽杉木幼苗试验观测结果表明,经几种源植物水浸液处理后杉木叶绿素含量、叶片气孔孔径及其大小均比对照明显提高,叶片质膜透性则明显降低,但气孔频数无显著影响,其中木荷对提高叶绿素含量和降低质膜透性效果最佳,与杉木对照(CK_Ⅰ)和清水(CK_Ⅱ)处理相比,木荷1:6水浸液处理的杉木叶绿素含量分别提高49.3％和52.5％,而质膜透性分别下降30.6％和26.3％。檵木对提高杉木叶片气孔孔径及其大小效果最佳,与清水(CK_Ⅱ)处理相比分别提高27.1％和30.3％。水浸液浓度越大,其叶绿素含量、气孔孔径及其大小越大,则质膜透性越低。更多还原

【Abstract】 Chinese-fir seedlings were treated with different concentration aqueous extracts from leaves and stems of Pho-tinia davidsoniae , Woodwardia japonica , Dicranopteris dichotoma , Castanopsis fargesii, Pinus massoniana , Schima superba , Syzygiu buxifolium , Lonopetalum chinensis and the control (Chinese fir and water). The results show that the chlorophyll content, aperture and size of stoma are increased markedly, and the membranous permeability of the leaf are decreased markedly, which are treated by the aqueous extracts of the source plant species after six years. There are no marked effects on the stomatal density, in which the effect of Schima superba on the chlorophyll content and the membranous permeability is the best, compared with the treatments of Chinese fir and water, its chlorophyll content is increased by 49. 3 % and 52.5%, and its membranous permeability is decreased by 30. 6 % and 26. 3 % ; the effect of Lono-petalum chinensis on the aperture and size of stoma is the best, compared with the treatment of water, its aperture and size of stoma are increased by 27. 1% and 30.3% . Meanwhile, the higher the concentration of the aqueous extracts is, the greater the chlorophyll content, stomatal aperture and size are and the lower the membranous permeability is.更多还原
