| Abstract: |
| In order to study the influences of different stocks（3309-144，3309-173，SO4-20，1103P-768，1103P-VCR107，1103P-VCR 119 and 1103P-CFC60-30） on Cabernet Sauvignon， the grape growth，photosynthetic parameters and chlorophyll content were detected. The results showed that stock had significant influences on the growth，photosynthetic parameters and chlorophyll content of Cabernet Sauvignon. The net photosynthetic rate（Pn），stomatal conductance（ Gs） and instantaneous carboxylation efficiency（ Pn/Ci） of Cabernet Sauvignon/1103P-VCR119 were higher than those of others，while the intercellular concentration of carbon dioxide（ Ci） was
lower，so photosynthesis productivity of the variety behaved better，its growth and chlorophyll content were higher than those of others. Thus，1103P-VCR119 was the most suitable stock for Cabernet Sauvignon in the area of drought and soil salinization. |
