Abstract: Researches on the production and growth of stump sprouting of Hippophae rhamnoide ssp.sinensis were infrequently reported,and the relationship between sprout characteristics and population structure was not well documented.To further understand the functions of decapitation for stump sprouting,the spout growing dynamics were analyzed,the effect of the stump sprouting on the population maintenance and stability was studied.No sprouts were found from the mother plants without decapitation (control),while sprouts ranging from 6.0 to 25.0 were produced from the stumps of decapitated trees (treated).The maximum growth heights of the cut trees were between 28.3 and 63.0 cm,while the length of new shoot from the intact ones was only 7.5 cm.The population structures of the control groups were stationary or senescent,but the treated groups showed incremental pattern. There were one growth peak of shoot height showing in June-July for the control groups and two peaks in May-June and September for the cut groups.It is concluded that decapitation can not only promote sprouting,but also accelerate the sprout growth and stabilize the population structure.
