Abstract:
To reveal the different species vine plant tolerance to high temperature,and provide a theoretical and applicatory basis for the vines vegetation in the northern city and mountain,annual function leaf samples (Humulus scandens,Parthenocissus quinquefolia,Parthenocissus inserta,Campsis grandiflora) were selected as experimental materials,heat resistance of four kinds of lianas by using conductance method together with the logistic equation were studied.The results indicated that with the rise of treated temperature,cell hurt rate of leaf segments of four kinds of lianas increased with trend of ‘slow-fast-slow’,showed typical ‘S’ curve,the significance test of which fitted logistic equation.Semi-lethal high temperature of four kinds of lianas divides from 59.50 ℃ to 64.54 ℃,semi-lethal high temperature of C.grandiflora (64.54 ℃) was the highest in the four kinds of plant,while H.scandens (59.50 ℃) was the lowest in the four kinds of plant.The heat resistance of four kinds of plant followed the order：C.grandiflora>P.inserta>P.quinquefolia>H.scandens.
