| 摘 要： | 研究了红树科Rhizophoraceae的木榄Bruguiera gymnorrhiza、海莲Bruguiera sexangula、角果木Ceriops tagal和秋茄Kandelia candel;马鞭草科Verbenaceae的白骨壤Avicennia marina;紫金牛科Mysinaceae的桐花树Aegiceras corniculatum和海桑和Sonneratiaceae的海桑Sonneratia caeseolaria次生木质部的结构与进化关系,红树科植物的次生木质部结构比马鞭草科、紫金牛科和海桑科的植物原始;红树科中的竹节树属Carallia和山红树属Pellacalyx为陆生的非红树植物,它们次生木质部结构比海生的红树料红树植物木榄属、秋茄属、角果木属更为进化,即导管为单穿孔、管间纹孔式为互利式纹孔.单穿孔的导管存在,是长期的进化过程中,遇到干旱环境而产生的特化现象,而海生红树科植物进入海滩沼译后,木质部仍具有原始性状.

| Abstract: | A study on the relation between the evolution and structure of secondary xylem of the mangrove Bruguiera sexangula, Bruguiera gymnorrhiza, Ceriops tagal and Kandelia candel (Rhizophoraceae), Avicennia marina (Verbenaceae) , Aegiceras corniculatum (Mysinaceae) and Sonneratia caeseolaria (Sonneratiaceae) is made. The results are shown as follows: Secondary xylem of mangrove species in Rhizophoraceae is more primitive than those of mangrove specie. in Verbenaceae, Mysinaceae and Sonneratiaceae , Carallia and Pella- calyx belong to Rhizophoraceae of terrestrial plants but are not mangrove species and they have more evolu- tionary secondary xylem, namely, simple perforation vessel and alternate pit-pair, than mangrove species such as Bruguiera, Ceriops and Kandelia (Rhizophoraceae). The form of simple perforation vessel is a specialization phenomenon in dry environment during the long evolution. But the secondary xylem characteristics of man- grove species in Rhizophoraceae remained primitive, after they entered the seashore wetlands. |
