| Abstract: | In this paper, the germplasm resources, classificatory distribution, as well as ecobiological characteristics of Hippophae in Gansu province have been investigated. Three species and two subspecies have been found in Gansu, named H. rhamnoides subsp. sinensis; H. rhamnoides subsp. turkestanica, H. neurocarpa and H. thibetana, and described from morphological characters to contents in fruits uspectively. Meanwhile, the relationships between its distribution and elevation, air temperature, and precipitation have been analized. It is shown that Hippophae L. is a kind of water loving, sun deciduous trees, resistant to drought, cold and barren. According to its ecobiological traits, the Hippophae growing areas in Gansu can be divided into following three districts: 1) Gannan-qilianshan district; 2) Hexi desert district; 3) Lanzhou and east of it district. As its dioecious pollination and facultative vegetative propagation, Hippophae is rich in germplasm resources so that it is necessary to build up specific plantations for its utilization propect, thus some good ideas about how to protect, further develop it, and strong then research work also been propounded in this paper. |
