摘要
在实验室条件下研究了温度、光照等因素对毛红椿种子萌发的影响。结果表明:毛红椿种子萌发最佳温度是25～27℃;浸种可以提高毛红椿种子发芽势和发芽率,加快种子的发芽;且浸种20 h,发芽势和发芽率达最大值;光照会抑制毛红椿种子发芽;0.3%高锰酸钾溶液消毒处理能显著促进毛红椿种子萌发。
Effects of factors such as temperature and light on seed germination of Toona ciliata var.pubescens were studied in laboratory condition.The results showed that the appropriate temperature was 25-27 ℃.Seed soaking could enhance the germination percentage and germination energy and shorten germination time.The highest germination percentage and germination energy could be reached after soaking for 20h.Illumination could restrain seed germination.Sterilizing treatment with 0.3% potassium permanganate solution could promote the germination of T.ciliata var.pubescens seeds.
