摘要:
叶片是植物应对环境变化较为敏感的器官,叶解剖结构在一定程度上也体现出了树木对特殊生境的适应能力。本研究通过对鲁东丘陵石灰岩山地同质生境内11个树种叶片以及叶脉的解剖结构分析,阐明植物对干旱生境的适应特征。研究结果表明,各树种均为异面型叶,该类型叶片在解剖结构上具有显著的栅栏组织和海绵组织区分。叶表皮厚度在不同树种之间无明显差异,但上表皮普遍较下表皮厚(上表皮平均厚度为34.66 μm,下表皮平均厚度为17.87 μm)。分别按乔、灌、藤三种生活型进行统计,发现叶片上下表皮厚度在生活型之间差异并不显著。各树种叶片均具有较发达的栅栏组织,而海绵组织排列较为稀疏。栅栏组织厚度与海绵组织厚度平均比值为2.42。在叶脉解剖结构中,各树种1级叶脉木质部厚度与韧皮部比值在1.43—5.30之间,且在树种间有显著差异,但该比值在乔、灌和藤三种生活型之间的差异不显著。叶脉解剖性状与叶片解剖性状存在显著相关(P < 0.01 )。栅栏组织厚度与海绵组织厚度比值、叶脉木质部厚度在一定程度上表征了树种对干旱生境的适应能力。该研究从叶解剖特性方面阐明了叶片对干旱生境的适应特征,可为未来干旱瘠薄山地植被修复树种选择提供参考。(图4 表4 参46 )
Abstract:
Leaves serve as the important and sensitive organs to environment changes. The leaf anatomical traits reflected the adaptation of trees to some special environments. 11 co-existing tree species from the common environment of limestone mountain area in eastern Shandong province were selected. The seven anatomical traits of leaf and leaf veins were examined and recorded, including the upper epidermis thickness, the palisade tissue thickness, the spongy tissue thickness, the lower epidermis thickness, the main vascular diameter, the xylem thickness, and the phloem thickness. The results showed that the leaves of these 11 tree species belonged to heterofacial leaves and the differentiation of palisade cells and spongy tissues was obvious in the leaf cross section . The leaf epidermis thickness did not show significant differences among tree species, however, the upper epidermis thickness was generally larger than the lower epidermis thickness. The average thickness of the upper epidermis of the 11 species was 34.66 μm and the average thickness of the lower epidermis was 17.87 μm. The average thickness of leaf epidermis did not show obvious differences among arbor, shrub and vine. The obvious palisade tissues were shown in all 11 tree species, while spongy tissues arranged sparsely. could be considered as an important index for the tolerance assessment of tree species to arid environment. The average ratio of palisade tissue thickness to spongy tissue thickness of 11 species was 2.42. In the leaf vein anatomy, The ratios of xylem and phloem thickness in leaf veins were 1.43-5.30, showing significant differences among 11 tree species. However, the ratios in three life type, arbor, shrub and vine, did not show differences. There were significant correlations among leaf vein diameter, xylem thickness and phloem thickness in the vein (P < 0.01). To a certain extent, the ratios of palisade tissues and spongy tissues thickness, the xylem thickness in leaf vein might serve as important ind ices for the tolerance assessment of tree species to arid environment. This study shows some relative characteristics of leaves to arid habitats according to leaf anatomical traits, which would provide some reference s for the selection of tree species for the vegetation restoration in arid limestone mountain areas in the future.? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
