摘　　要：玛瑙桂莪术(Curcuma kwangsiensis‘Manao’)根茎适当控水能提前花期和提高开花率.本试验通过催芽和水养期间对玛瑙桂莪术根茎进行控水处理,探究控水对其根茎生长及开花的影响.催芽期间对其进行每5 d加水1次效果最好,出芽率为96%,开花率达68%,花枝高度达12.31 cm.水养期间控水试验表明根茎水养8 d后控水6 d最适宜,该处理组开花率和花枝高度比其它处理组高.在控水强度试验中发现水养6 d后控水3 d的处理组根茎含水量较低、电导率以及脯氨酸含量较高,有利于根茎进行正常的生理活动.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.
