摘  要:
为提高云南松(Pinus yunnanensis Franch.)幼苗对高盐胁迫的适应能力,通过0~2 500 mg/L的矮壮素对云南松进行浸种处理,研究其在高盐胁迫下(200 mmol/L NaCl)的生长情况。结果表明,1 000 mg/L矮壮素浸种效果最好,与对照相比,发芽率增加79.25%,发芽势增加80.54%,茎粗增加22.35%,鲜重增加38.83%,干重增加21.55%,可溶性糖含量是对照的5.55倍,叶绿素总量增加15.42%,SOD活性是对照的2.90倍,MDA含量下降了28.90%。表明矮壮素对云南松在高盐环境下的生长具有良好的协助作用。

摘  要:
In order to improve the adaptability of Pinus yunnanensis Franch.and study the growth of P.yunnanensis Franch.in the high NaCl stress,the seeds of P.yunnanensis Franch.were treated with 0~2 500 mg / L chlormequat chloride(CCC).The results showed that after 1 000 mg / L CCC seed soaking,it got the best salt resistance effect.Compared with the control,the germination rate,germinative force,the stem diameter,wet weight,dry weight,the content of chlorophyll increased by 79.25%,80.54%,22.35%,38.83%,21.55% and 15.42% respectively,and the content of soluble sugar and SOD were 5.55 and 2.90 times of the control respectively,the content of MDA decreased by 28.90%.It was concluded that the CCC was helpful for the growth of P.yunnanensis Franch.in the high NaCl stress.
