C_4植物蒺藜(Tribulus terrestris L.)叶部的解剖学特点及其向光性运动

C_4植物以其高效率的光合作用,受到人们的广泛注意。研究者从生理、生化、解剖等各个角度去探讨它们的机理。我们在研究工作中发现蒺藜(Tribulus terrestris L.)是一种 C_4植物,且具有极为明显的运动现象,尤其是叶子的向光性运动更为显著,其叶部的解剖构造也相应地具有某些特点。

ANATOMICAL CHARACTERISTICS AND PHOTOTROPIC MOVEMENT OF LEAVES OF Tribulus terrestris L.(C_4 PLANT)

Kranz anatomy has been recognized as an anatomical characteristic of the leaves of C_4 plant.However,a multiplicity of the structure of C_4 plants still may be seen.Some C_4 plants don't have typical Kranz anatomy(e.g.Garnotia stricta,Arundinella nepalensis,Triodia pungens, Suaeda torreyana and Salsola Kalii etc.).Tribulus terrestris L., C_4 plant,has twogreen bandslocated on both sides beneath the ventral epidermis of the anis of the compound leaf,in addition to Kranz anatomy in the cross section of the le...
