Abstract: Abstracts: Allium plants have high nutritive and economic value. In order to protect and develop allium plants and screen out the optimum germination treatment, through the international seed communication channel of Xi’an botanical garden, 8 allium plants were collected from other botanical gardens in the world, and the influence of different processing methods (concentrated H₂SO₄, PEG and cold stratification treatment) on 9 species of allium seed germination was studied. The results showed that different treatments had different influences on seed germination. Both concentrated H₂SO₄ treatment for 5 min and 15% PEG treatment for 6 h could promote seed germination, the germination rate of 4 species was above 80% under concentrated H₂SO₄ treatment, but there was only one species under PEG treatment. Only 6 species could germinate under cold stratification treatment, and the germination rate was 7%-64%. Only 4 species could germinate under CK treatment, and the germination rate was 12%-57%. Concentrated H₂SO₄ treatment was the best among these three treatments, it could promote allium seed germination rate efficiently. Allium seed in this study had weak responses to concentrated H₂SO₄ and PEG, which might be related to dormancy mechanism and it needed further study.
