Abstract Proper water stress could advance the flowering period and increase the flowering percentage of Curcuma kwangsiensis‘Manao'. The effects of water stress on germination and flowering of Curcuma kwangsiensis‘Manao' during germination and hydroponics were studied. The results showed that watering once every five days was the best method for germination,and that the germination percentage was 96%, flowering percentage achieved 68%,the flower height achieved 12.31 cm. The treatment with water stress for 6 d after hydroponics for 8 d, achieved the more higher flowering percentage and flower height than other treatments.It was found out that water stress for 3 d after hydroponics for 6 d, the lowest water percentage of rhizome was achieved,while the conductivity and proline content were higher than other treaments.Under this treatment, the normal physiological activities of the rhizomes was much more well.
