摘要
用生物活性水对矮牵牛种子和苗期生长进行处理,探讨生物活性水在矮牵牛种子发芽率和后期营养生长过程中的影响。结果表明:生物活性水处理过的矮牵牛种子的发芽率、幼苗的茎粗、叶片数等形态指标及叶绿素含量均高于对照组,其中600倍为最适矮牵牛种子萌发的浓度,400倍到800倍均能促进主根的生长,200倍稀释液可抑制矮牵牛株高的伸长生长,促进其进一步矮化,且生物活性水在一定范围内存在浓度效应。
The biological activie water is used to treat seeds and seedling growth processing to explore the impact of the of bioactive water in petunia seed germination rate and late vegetative growth process.The results show that because： of bioactive water,Petunifa seed germination rate,stem diameter,number of leaves morphological indicators and chlorophyll content of seedlings are higher,and 600 times is suited to the concentration optimal petunia seed germination.It is able to promote the growth of the taproot 400-fold to 800-fold,200-fold dilution can inhibit the petunia plant height elongation growth,promote further dwarf,and the biological activity water in a certain range in the concentration effect.
