摘要
为了解外源有机硒对铁皮石斛和金钗石斛组培苗生长的影响,分析了喷施不同浓度有机硒肥对铁皮石斛和金钗石斛组培苗鲜重、硒含量、叶绿素含量、多糖含量和黄酮含量的影响。结果表明,铁皮石斛和金钗石斛各指标含量均随着有机硒浓度的增加而提升;当铁皮石斛组培苗在有机硒浓度为1.00~1.50 mg/L时,其鲜重、硒含量、叶绿素含量、多糖含量和黄酮含量有显著增加,当有机硒浓度为1.50 mg/L时,各指标达到最高。当金钗石斛组培苗在有机硒浓度为0.75~1.25 mg/L时,各指标含量有显著增加,在有机硒浓度为1.25mg/L时达到最高。综上,适量的外源硒对铁皮石斛和金钗石斛组培苗的生长具有积极影响。
To investigate the effects of organic selenium on the growth of Dendrobium officinale and D.nobile in tissue culture seedling,this study examined the impact of spraying different concentrations of organic selenium fertilizer on weight,Se content,as well as chlorophyll,polysaccharide,and flavonoid contents in the seedlings.The results showed that all measured indices in both Dendrobium species increased with elevating concentrations of organic selenium.For D.officinale seedlings,the weight,Se content,chlorophyll,polysaccharide,and flavonoid levels showed significant increases when the organic selenium concentration ranged from 1.00 to 1.50 mg/L.At the concentration of 1.50 mg/L,all parameters reached their peak levels.For D.nobile seedlings,the content of all indices significantly increased at organic selenium concentrations between 0.75 and 1.25 mg/L,and peaked at a concentration of 1.25 mg/L.This finding demonstrated that appropriate organic selenium effectively promotes the growth of both D.officinale and D.nobile in tissue culture seedlings.
