干旱胁迫对蕨类植物生理指标的影响
Effect of Drought Stress on Physiological Index of Fern
摘要
Abstract
[ Objective ] The physiological index variation of fern was studied under drought stress. [ Method ] By means of artificial simulated drought stress and rehydration, the effect of drought stress on physiological indexes ( leaf relative water content, relative conductivity, chlorophyll content and free proline content) of five ferns ( Nephrolepis auriculata, Pteris multiflda, Pteris vittata, Adiantum capillus and Cyclosorus interruptus ) was studied in our paper. [ Result ] With drought stress time prolonging, the leaf relative water content and chlorophyll content of five ferns showed decrease trend, while there was an increase trend in relative conductivity and free proline content; the physiological indexes of Nephrolepis auriculata under drought stress were better than other ferns, with obvious difference after 12 days of stress, and it showed that Nephrolepis auriculata had strongest drought-resistant ability; after rehydration, the physiological indexes of five ferns recovered at different degree. [ Conclusion] Our study could provide theoretical basis for the development and utilization of fern.关键词
