Abstract

In order to clarify the adaptability of woody ferns to drought stress,3-year-old Alsophila spinulosa seedlings were selected for drought stress and rehydration treatment through potted water control.The changes of water potential and photosynthesis in the leaves of Alsophila spinulosa were studied after 3,6,9,12 days of drought and after 3,6,and 9 days of rehydration.The results showed that with the prolongation of drought time,the water potential of Alsophila spinulosa leaves showed an overall upward trend,the net photosynthetic rate (Pn) showed a downward trend,the inter-CO2 concentration (Ci) first decreased and then increased,and the stomatal conductance (Gs) and transpiration rate (Tr) showed a trend of decreasing-increasing-decreasing.In the early stage of drought (6 days ago),the change trend of Pn,Gs and Ci was basically the same,and the decrease of Pn was mainly caused by stomatal limitation.In the later period of drought (after 6 days),the change trend of Pn was inconsistent with that of Gs and Ci,and the decrease of Pn was mainly caused by non-stomatal limitation.After rehydration,Pn and Tr of Alsophila spinulosa leaves recovered to the level of adequate water supply,while the water potential,Gs and Ci recovered to the level above that of adequate water supply.At the same time,the water use efficiency (WUE) of Alsophila spinulosa leaves increased first and then decreased with the prolongation of drought time,and showed a downward trend after 6 days of drought.And after rehydration,the WUE basically recovered to the level of adequate water supply.Taken together,Alsophila spinulosa has relatively poor drought tolerance and relatively strong rehydration recovery ability.Through the analysis of the photosynthetic physiological characteristics of drought stress and rehydration process,it is preliminarily considered that Alsophila spinulosa is a drought-avoiding plant.

Key words： Alsophila spinulosa; photosynthesis; drought stress; rehydration; water use efficiency; water potential
