Taking Cucurbita maxima and Cucurbita moschata as root stocks, and 'Jinyou No 3' cucumber as scion, the effects of different root zone temperature conditions optimal temperature (CK) (18-20t), suboptimal temperature (13--15°C) and low temperature (8--10 T!) on the growth and photosynthesis indexes were studied. The results showed that, compared with optimal temperature (CK), suboptimal temperature and low temperature produced a significant inhibition of growth on cucumbers. The plant height, stem diameter, leaf area, number of leaves and dry weight of aboveground part were all reduced, dry weight of underground part and root shoot ratio all increased, while the inhibition was more significant at low temperature. Low and suboptimal temperature conditions also reduced SPAD value, net photosynthetic rate, transpiration rate, intercellular C02 concentration and stomatal conductance of the grafted cucumber. And there were differences between different grafted seedlings, and seedlings with 'black seeds' as stock performed better than those with 'white seeds' as stock at low temperature.
