[Objective] The aim was to research the effects of polyethylene glycol(PEG-6000)on the plant height and leaf area of hot pepper seedlings. [Method] With the seeds of dry-making hot pepper F1 hybrids as the tested material, the simulation dry environment was simulated by PEG-6000 at 4 levels of 0%(CK), 5%, 10% and 15% according to weight rate (W/V) to deal with the hot pepper seedlings. [Result] With the increasing of PEG-6000 concn., the plant height of hot pepper seedlings showed a tendency of first increasing and then decreasing: compared with the CK, the plant height were increased by 13.8% and 8.8% resp. under 5% and 10% concn. stress and the plant height was decreased by 17.4% under 15% concn. stress. The leaf area of hot pepper seedlings was decreased with the rising of the PEG-6000 concn.: compared with the CK, the leaf area were decreased by 33.8%, 58.7% and 78.5% resp. under 5%, 10% and 15% PEG-6000 stress. [Conclusion] 5% PEG-6000 stress had a promoting effect on the plant height of hot pepper seedling; more than 10% PEG-6000 stress had a restraining effect on the plant height of seedlings; all kinds of PEG-6000 concn. restrained the increase of leaf area of seedlings.
