Study on Germination Characteristics of Alhagi sparsifolia Seeds
In this paper,the seeds of Alhagi sparsifolia were collected from wild Alhagi sparsifolia grass seed base in Turpan area of Xinjiang Province from 2020 to 2023,and the germination characteristics of Alhagi sparsifolia seeds under different dormancy breaking methods and dif-ferent experimental conditions were studied.The results showed that the germination rate of Alhagi sparsifolia seeds was improved after the seed dormancy was broken by pretreatment.The optimum germination temperature was 30℃.Seed-skin rubbing treatment and concentrated sulfuric acid soaking pretreatment had the best effect on breaking dormancy of Alhagi sparsifolia seeds,the germination rate was up to 100% and the germination time was faster.Distilled water soaking treatment had no obvious effect on seed germination.When the soaking temperature gradually increased and the soaking time extended,the germination rate was significantly increased.After soaking in 90℃distilled water for 2 hours,the germination rate was up to 70% .
