Abstract

Abstract: In this experiment, polyethylene glycol（PEG-6000） was used to simulate drought conditions, the effects of PEG-6000 on five species including Lycopersicon esculentum, Zea mays L., Brassica chinensis, Citrullus lanatus and Raphanus sativus seed germination and seedling growth were investigated. The results showed that the germination rate, germination potential, germination index, germination rate and average germination time of the five tested plants were obviously affected under high concentration PE-6000 treatment. The comprehensive evaluation of the subordinate function values showed that the order of drought resistance of the five tested plants was as followsZea mays L. > Brassica chinensis > Lycopersicon esculentum > Citrullus lanatus > Raphanus sativus.

Key words: polyethylene glycol, winter crops, drought resistance, Hainan province
