Abstract：Polyamines accumulation under osmotic stress and water logging wascompared in leaves and leaf segments of two wheat varieties, drought tolerantehanxuan No. 4 and drought sensitive longchun No. 10. The results show that pu-trescine content of two wheat rarieties both increased greatly under two stress,whereas spermidine and cadaverine content is much less under osmotic stress. Pu-trescine content of Hanuan No. 4 leaves is much higher than that of Longchun No.10. Under water logging, however, putrescine accumulation in two wheat varietiesis similar, indicating that as regards putrescine bios ythesis and degradation, os-matlc stress and water logging are different c0nditions. Although under light os-motic stress, ployamine content increased pronouncedly, implicating that ploy-aminemay act as second messenger.
