- 摘要:
- 以西藏野生鸢尾种子为试材，研究了不同发芽条件对西藏野生鸢尾种子发芽率的影响。结果表明：浸种温度对种子的萌发有一定的影响，暗环境和高锰酸钾溶液浸种有利于种子的萌发，IBA在一定浓度范围内能有效提高种子的发芽率，22℃的培养温度是种子发芽的最适温度，变温对鸢尾种子的发芽没有明显的影响；提高西藏野生鸢尾种子的发芽率的措施是，在种子采集后进行低温处理，第2年4、5月份经45~65℃的温汤浸种或IBA溶液处理后在22℃暗环境下进行发芽试验。
- Abstract:
- Taking the seeds of wild Iris clarkei as test material，the effect of different germination conditions on the germination rate of seed of Iris clarkei were studied.The results showed that submergence temperature affected seed germination；dark environment，submergence in KMnO4 solution or exposure to IBA were conducive to seed germination；the prime temperature was 22℃ and fluctuation in temperature did not affect seed germination.In combination of these factors，and suggested that collected seeds were subjected to cold stress，then submerged to 45~65℃ KMnO4 solution or exposed to IBA at April or May of next year，finally placed in a dark environment of 22℃ to promote germination.
