| Abstract: | The present paper reports karyotypes in 4 species and 5 subspecies of Hippophae L.in China. It is found that all of the species and subspecies are diploid, with 2n=24, their complements are made of m and sm chromosomes and of them only H. thibetana has a pair of satellites. All of these karyotypes are symmetrical and primitive. It can be simplied as follows:Hippophae neurocarpa 2n = 2x = 24 = 18m+6sm, H. thibetana 2n = 2x = 24 = 14m(2sat)+ 8sm, H. rhamnoides L. ssp. gyantsensis 2n=2x=24= 18m+ 6sm, H.salicifolia 2n = 2x = 24 = 10m + 14sm, H. rhamnoides L. ssp. sinensis 2n=2x=24 = 18m + 6sm, H. rhamnoides L. ssp. turkestanica 2n = 2x = 24 = 20m + 4sm;Hi. rhamnoides L. ssp. yunnanensis 2n = 2x = 24 = 14 + 10sm, H. rhamnoides L.ssp. mongolica 2n = 2x = 24 = 16m + 8sm. |
