以采自甘肃民勤东镇和西渠镇不同荒漠区生长的沙葱种子为试材,在人工气候培养条件下,研究了吸水量、浸种处理、恒温处理和萌发天数对其吸水量和发芽特性的影响。结果表明:沙葱种子吸水饱和时间为12h;适宜浸种时间为12h,适宜发芽温度为20℃,适宜萌发天数为12d;西渠镇生长的沙葱种子发芽能力优于东镇沙葱种子,表明生长在不同环境条件下沙葱种子发芽能力存在差异。
Taking the Allium mongolica seedlings grown in different desert areas of Minqin East Town and Xiku Town of Gansu Province as test materials, the effects of water absorption, soaking treatment, constant temperature treatment and days of germination on their water absorption and germination Effect of characteristics. The results showed that the water saturation time of Allium mongolicum seeds was 12h, the suitable soaking time was 12h, the suitable germination temperature was 20 ℃, and the suitable germination days were 12d. The germinability of Allium mongolicum seeds grown in Xichu was better than that of Allium mongolicum seeds The growth of Allium mongolicum seed germination ability is different under different environmental conditions.
