摘要:
2016 年8 月,对‘丽玫’小叶蚊母树Distylium buxifolium ‘Limei’ 当年生叶片特征、气孔密度及光合特性进行测定。结果表明,春、夏各梢段叶片均从基部到顶部逐渐变小,尤其春梢顶部的叶片长、宽、叶面积、单叶质量均显著小于其它位置的叶片;叶色参数、气孔密度及大小总体差异不大。夏梢叶片在叶片长度、宽度、叶面积、气孔密度这些指标上与春梢叶片相差不大。试验显示,叶片最大净光合速率11.67 ~ 15.01 μmol·m-2·s-1,光补偿点7.50 ~ 17.50 μmol·m-2·s-1,光饱和点1 104 ~ 1 419 μmol·m-2·s-1,节间长度11.33 ~ 19.46 mm,说明‘丽玫’不仅耐修剪,而且具有良好的耐荫性和耐强光能力,对生长环境适应性强,是一种优良的园林地被植物。
Abstract:
Determinations were carried out on phenotype, stomatal density and photosynthetic properties of Distylium buxifolium ‘Limei’ leaves atdifferent parts on August of 2016 in Lisui, Zhejiang province. Results showed that leaves were smaller from the base to the top both from spring andsummer shoot, especially leaf length, width, area and single leaf weight at the top of spring shoot was evident smaller that that at other parts, but ithad no difference of leaf color, stomatal density and size among leaves at different parts. Leaf length, width, leaf area, stomatal density of summerleaves had no evident difference with that of the spring. The experiments demonstrated that the maximum net photosynthetic rate was 11.67-15.01,light compensation point 7.50-17.50, light saturation point 1104-1419 with internode length of 11.33-19.46mm. It showed that D. buxifolium ‘Limei’had advantages of tolerance of trimming, shade and light, and would be a good ground cover plant.
