Comparison of the Root Structures of Sansevieria trifasciata in Hydroponic Culture and Soil Culture
Objective] To research the adaptation of Sansevieria trifasciata in hydroponic culture and soil culture, and to provide theoretical foundation for the research on hydroponic-cultured flowers. [Method] With S. trifasciata as the material, freehand section was made. Observa-tion was carried out under two modes of hydroponic culture and soil culture. Changes of root appearance and anatomical structure were compared. [Result] In morphology, S. trifasciata roots under hydroponics culture grew slowly with smaller diameter and degenerated root hair. However, S. trifasciata roots under soil culture had strong root with developed lateral root and rough surface. In anatomical structure, the root epidermis of S. trifasciata roots under hydroponics culture was thinner, cortical cell volume was greater;marrow accounted relatively small area in the column area;xylem degradation appeared. There were a few crystal cells in the cortex of S. trifasciata roots. [ Conclusion] Root structure of S. trifascia-ta under hydroponics culture changes in different degrees, which dose not affect its normal growth.
