Study on Tracheary Elements of Selaginella

YANG Yang et al (College of Life Sciences,Beijing Normal University,Beijing 100875)  
[Objective] The aim was to study the type and characteristic of tracheary elements of Selaginella.[Method] The stem of four species of Selaginella plants treated by the segregation method was observed by scanning electron microscopy(SEM).[Result] Selaginella sinensis and Selaginella davidii had tracheids and the tracheary elements with scalariform perforation plates were observed in the latter,which were conferred as vessel.Only vessels were observed in Selaginella sanguinolenta and Selaginella pulvinata,including two types of scalariform perforation plates and reticulate-scalariform perforation plates.The tracheary elements of S.sanguinolenta and S.pulvinata were the most evolutionary,followed by S.davidii and that of S.sinensis was the most primitive in the four species of Selaginella.The types of tracheary elements of S.pulvinata,S.davidii and S.sinensis were first reported.The different types of tracheary elements had some correlation to their habitats.[Conclusion]The research laid the foundation for validating the difference of tracheary elements in isomorph leaf type of Selaginella and heteromorphic leaf type of Selaginella,and discussing the evolution problem of the tracheary elements of Selaginella.
