Abstract:
5 year old G inkgo b iloba L. seed lings was selected to m easure the changes in physio log ica l and biochem ical indexes of leaves and ultrastructure o f ch lo roplasts under pro long ed drought stress. The results show tha t ch lo roplasts ( Chl) content decreased w hen the drought stress had lasted 30 days, wh ileMDA content and the ac tiv ities of SOD in c reased, wh ich resulted in the reduction o f the activ ities o f CAT. A t the sam e time, pro line and solub le suga r content w ere g radua lly increased, w hile content of so lub le pro te in decreased a t first and then increased aga in. Therew ere signifi cant differences in every phy sio logy indexes w ith the control except the activ ities o f SOD. Ch loroplast lam ellae becam e loose g radually, whereas the number and size o f osm ioph ilic g ranu le increased during drought stress till the chlorop last d isappeared. There were no v ariations in som e physio log ical indexes for theG inkgo biloba L. leaves and chlorop last ul rastruc ture under drought stress fo r 30 d. SoG inkgo biloba L. has some adapta tion for drought
