A Study On Appearance And Anatomy Of Pugionium Cornutum (L.) Gaertn

This experiment to adopt the method that paraffin was cut into slices studied the structural growth process on appearance and dissect of Pugionium cornutum(L)Gaertn in germination period and young sprout ;And to adapt wild flower, fruit, seed and cultivated root,stem and leaf of Pugionium cornutum(L.)Gaertn in leaf lushing period and leaf exhausting period from EERDUOSI City proceeded the research on appearance and anatomies . the result enunciates:The organs of Pugiorium cornutum(L.)Gaertn in root, stem and leaf have starteddividing in germination period;the transporting tissue and storing water tissue in young sprout period has been divided;the ransporting tissue is flourishing,but the supporting tissue is unflourishing,so the root,stem and leaf of Pugionium cormutum(L)Gaertn is suitable for edibility . In addition, the pith of root and stem is flourishing for prosperous growth period and declining period ,the vascular tissue storing the nutrient and providing the nourishment for the biennial plant in next year from abnormal secondary growth is developing in pith ,unusual structure eg. epidermis and vice- epidermis, bubble form cell, short pipe numerators and wreath grid types leaf etc. in each organ of Pugionium comutum(L.)Gaertn.had been formed to adapt to dry environment,so the characteristics on appearance and anatomies in Pugionium cornutum(L)Gaertn. has closely of relation with its anti- drought and its adapting to desert environment.
