暖地泥炭藓(Sphagnum junhuhnianum)孢子形态及发育过程探讨
|
摘要
描述了暖地泥炭藓(Sphagnum junhuhnianum)孢蒴从翠绿色透明状球体历经黄绿色、淡褐色、褐色、具光泽的深咖啡色球体到最后喇叭状过程中孢子的形态特征。成熟孢蒴中孢子的数量(71 631±12 751)个。成熟孢子四面体结构清晰,极面观呈圆三角形,赤道面观呈近扇形,直径(23.27±1.05)μm,均出现三裂隙结构,唇状,稍细,长为极半径的2/3,裂隙表面布满疣状颗粒物,近极端三面凹陷无褶皱,分布少量疣状颗粒物,远端面不平整,布满疣状颗粒物。
This article describes Sphagnum junhuhnianum spore morphology of the development process of capsula,which from green transparent ball to yellow green,light brown,brown,shiny dark brown and end of the horn shape.The spore number of mature capsula is about 71 631±12 751.The characteristics of mature spore that is tetrahedral,rounded-triangular in polar view,nearly sector in equatorial view,three aperture and(23.27±1.05)μm in diameter.Trilete1 is distinct,narrow accounting for 2/3of the spore radius and distributed a lot of verrucous particulate matter.The surface in polar view is sunken,smooth and distributed litter verrucous particulate matter.The undersurface is uneven and distributed numerous verrucous particulate matter.
