In order to the best photosynthetic response curve model for Actinidia arguta was studied. Eight Actinidia arguta cultivars including two male plants cultivars(‘Tukiyama’, ‘Senmao A’) and six female plants cultivars(‘Kui Lu’,‘LD133’,‘Ken’s red’,‘Daijitu’,‘Kitaro’ and ‘Garnet’) were selected from field plots at Dalian University and beilin agricul tural research institute in northeast China. The photosynthesis light response curve was measured in eight Actinidia arguta cultivars using the Li-6400 portable photosynthesis system. Four light response curve models were applied to fitting its light response curve. Four light response curve models were applied to fitting its light response curve of Eight Actinidia arguta cultivars. The results show that YEM in Four light response curve models could fit well the photosynthesis light response curves. In two males and six female plants cultivars,Comparing light-response parameters fitted by the YEM for these cultivars of Actinidia arguta. Rd order from weak to strong was ‘Garnet’<‘Senmao A’<‘Tukiyama’<‘Kitaro’<‘Daijitu’<‘Kui Lu’<‘LD133’<‘Ken’s red’, Is order from weak to strong was ‘Garnet’<‘Kitaro’<‘Daijitu’<‘Ken’s red’<‘LD133’<‘Tukiyama’<‘Kui Lu’<‘Senmao A’, Ic order from weak to strong was ‘Senmao A’<‘Garnet’<‘Tukiyama’<‘Kitaro’<‘Daijitu’<‘Ken’s red’<‘Kui Lu’<‘LD133’, Pnmax order from weak to strong was ‘Garnet’<‘Ken’s red’<‘Kui Lu’< ‘Kitaro’ <‘LD133’ <‘Daijitu’ <‘Tukiyama’ <‘Senmao A’, α order from strong to weak was ‘Garnet’< ‘LD133’ <‘Tukiyama’ <‘Senmao A’<‘Kui Lu’ <‘Daijitu’ <‘Kitaro’< ‘Ken’s red’.
