摘要
采用2种工艺制作的海带提取液对药用植物牵牛进行浸种和叶面喷施实验。结果表明:海带提取液能显著提高种子的萌发率;促进牵牛根系的生长发育,增加根系体积、鲜重与干重;促进地上部分的生长,其干重、鲜重明显提高。叶片中叶绿素含量随幼苗的发育呈增加趋势;但在同一发育时期叶绿素a/b比值差异不显著,Chla、Chlb含量变化无一定规律。
The seed dipping and foliage test on medicinal herb, Pharbitis purpurea （L.） Voigt,with kelp concentrate prepared by two technics indicated that the concentrate could enhance seed germination significantly ;promoted growth and development of root system; and so increased root volume,fresh weight,dry weight. It also accelerated aerial part growth,fresh and dry weight.Chlorophyll content in lamina added gradually along with seedling development. Whereas, diversity for Chla/Chlb ratio was not distinct; Chla、Chlb content changed irregularly in same devolpmental period.
