cucumber (Cucumis sativus L.)inbred lines with different resistance to temperature stress were used in this experiment. The seedlings of line Q10 and Q21, with higher resistance to the chilling stress, had higher ability of resistance to the heat stress. And the seedlings of line T94 and T55, with lower resistance to the chilling stress, had lower ability of resistance to the heat stress. It seems that the resistance of cucumber seedlings to different temperature stress was similar. The influences of the ...
