摘要
应用光学显微镜观察中、高潮位生境下木榄(Bruguiera gymnorrhiza)和尖瓣海莲(B.sexangula.var.rhynchopetala)茎次生木质部管孔、射线和纤维的结构特征,并对相似生镜下2种木榄属植物和不同生镜下同种木榄属植物的茎次生木质部有关结构进行了对比分析。结果表明,同属的木榄和尖瓣海莲有部分相同的解剖结构特征;与高潮位相比,中潮位环境下生长的木榄属植物在木材微观结构的数量特征上表现出更强的环境适应性;相同潮位生境下,木榄比尖瓣海莲有更强的抗逆性。
Structural characteristics of vessels,rays and fibre of the stem secondary xylem in Bruguiera gymnorrhiza and B. sexangula. var. rhynchopetala were observed by optical microscope in the habitats of middle and high tide levels,the structures of stem secondary xylem of two Bruguiera species in the similar habitats and of the same Bruguiera species in the different habitats were compared. The results showed as follows. These two Bruguiera species had part of the same anatomical structure characteristics. Quantitative characteristics of wood microstructure of Bruguiera was more adapted to the environment in the habitat of middle tide zone. B.gymnorrhiza had higher resistance than B. sexangula. var. rhynchopetala in the similar habitats of the same tide level.
