摘要
采用L9(34)正交实验,通过置皿环境、微波辐射和激素浸种3个因素3种水平对云南松种子发芽的胚根和胚轴伸长的影响研究。结果表明,胚根长度和胚轴长度的最优处理为全天光照、无微波辐射、0.2 g/L的IBA溶液浸种。置皿环境显著地影响云南松种子胚根和胚轴的长度,全天光照有利于促进胚根和胚轴的伸长(19.88 mm和45.69 mm),激素浸种主要影响胚根的伸长,2 g/L的IBA溶液浸种显著促进胚根伸长。微波辐射对以上2个指标无显著的差异影响。
The L9（34） orthogonal design was applied to understand the effects of germinative environment,microwave radiation and hormone on radicle and hypocotyl length of Pinus yunnanensis seedlings.The results show that optimal treatment combination of improving radicle and hypocotyl length was whole-day lighting,non-microwave radiating and 0.2 g/L solution of IBA soaking seeds.Germinative environment significantly influenced radicle and hypocotyl length,in which whole-day lighting was benefit to elongate radicle and hypocotyl（19.88mm and 45.69mm,respectively）.Hormone solution soaking seeds primary affected on radicle length.0.2 g/L concentration of IBA solution facilitated radicle growth.There were no significant differences on above 2 parameters between the levels of microwave radiation.
