摘要
在温室盆栽条件下,对切花菊品种‘神马’(Chrysanthemum morifolium ‘Jinba’)接种5种不同的丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF),分别在苗期和花期,通过测定相关形态及生理指标,研究AMF对切花菊生长的影响。结果表明:与未接种对照相比,5种AMF均能不同程度地侵染切花菊根系,增加植株株高、叶片数、根长和花瓣面积等,促进切花菊生长。接种AMF能够增强切花菊根系活力,提高根系、叶片和花瓣中的可溶性糖含量(Glomus mosseae除外),从而改善渗透调节。综合分析,最终筛选出G.intraradlces是对切花菊生长促进效果最好的菌种。
The pot experiment was conducted in the greenhouse to study the effects of five kinds of different arbuscular mycorrhizal fungi(AMF) strains on growth of Chrysanthemum morifolium 'Jinba' by measuring some morphological and physiological indicators at young plants and blooming stages.The results showed that AMF treatments could significantly improve the plant height,leaf numbers,leaf area,root length and petal area of C.morifolium compared to the control of no inoculation.The AMF treatments could enhance root activity,increase the soluble sugar content in the roots,leaves and petals(except for Glomus mosseae),and thus improve the osmotic adjustment.As a result,G.intraradlces was screened out as the best strain for enhancing the growth of C.morifolium.
