- W2371272857 abstract "Chromosome count and karyotype analysis of root tip cell in invasive weedSorghum halepenseL.was reported.At the same time,some characters,such as chromosome number,chromosome ploidyet al,betweenSorghum halepenseL.and SorghumL.were compared.The results show that the chromosome number ofSorghum halepenseL.is 2n=34,the basic number of chromosome isx=17,which arises chromosome number variation comparing with the same species(x=10) in origin.The karyotype formula ofSorghum halepenseL.is 2n=2x=34=24m(2SAT)+10sm,which belongs to“2B”type、 There are a pair of SAT in the No.15 chromosomes.The chromosome length ratio is 2.30,Prop.of AR2 is 0.18,the index of asymmetry is 60.02%.There is not precise mathematical relationship in chromosome number betweenSorghum halepense L.andSorghumL.These show that the variantSorghum halepenseL.may be a new species,which evolved through wide crosses between invasive species(2n=4x=40,n=20)and other species in grass family(2n=4x=28,n=14)" @default.
