Seed Germination Characteristics and Response to Salinity and Drought Stress in Incarvillea sinensis var.sinensis and I.sinensis var.przewalskii
The aim of this study was to investigate the germination characteristics and stress resistance of Incarvillea sinensis var.sinensis and I.sinensis var.przewalskii seeds.The results showed that both species had rapid germination characteristics,but there were differences in their optimal germination temperature and stress resistance.The optimal germination temperature for I.sinensis var.sinensis seeds was 25℃,while for I.sinensis var.przewalskii it was 25℃and 20/30℃.Moreover,I.sinensis var.sinensis exhibited stronger resistance to salt and drought stress.Additionally,I.sinensis var.sinensis seeds were superior to I.sinensis var.przewalskii seeds in terms of shape,size,thousand-seed weight,and vigor.These results contribute to better utilization of the seed resources of these two plants and to improving their production and utilization effi-ciency.
