摘要:
电镜下观察并研究了假瘤蕨属植物的叶片附属结构。报道了蜡质颗粒、片层、柔毛和鳞片。叶片附属结构在数量及性质上的差别显示出种类与环境的适应性不同。结果表明,假瘤蕨属植物中土生的种类具有较多的蜡质颗粒、柔毛及鳞片,而附生的种类具有较多的颗粒及片层,这些叶片特征均与亚热带常绿阔叶林的生态环境相适应。
Abstract:
Detailed morphological study of the leaf appenages of the fern genus Phymatopteris in China under SEM is presented. The study reveals the wax granules,stripes,apophysis and hairs. Leaf appendages are constant in some species and variable in others in the aspects of quanlities and characteristics and thus of great significance in understanding the relationships between the species and the ecological environments adaptable. The results support that there are more wax granules,hairs and scales on the terrestrial species,and more granules and stripes on the epiphytic ones of this genus. All the frond appendage characters reveal an adaptation to ecological conditions of the fern genus Phymatopteris to the subtropical evergreen broadleaf forest.
