- 摘要:
- 以辣椒为试材，采用漂浮盘育苗的方法，设置不接菌（CK），接种摩西斗管囊霉（Funneliformis mosseae，Fm）、接种根内根孢囊霉（Rhizophagus intraradices，Ri）3个处理，通过在育苗基质中添加菌剂分别培育6个辣椒品种，探究丛枝菌根真菌（AMF）对不同辣椒品种吸收富集镉（Cd）及生长发育的影响，以期为辣椒实现高效、安全生产提供参考依据。结果表明：接种AMF促进辣椒幼苗生长，除“黔辣10号”之外，其余辣椒品种接种Fm、Ri的壮苗指数分别提高13.04%~131.82%、22.58%~161.11%。相较CK，Ri处理的‘辣研201’‘螺丝椒XJ-16-9’‘黔辣10号’‘辣研101’‘黔辣16号’‘辣研102’地上部富集系数分别降低9.19%、4.79%、43.31%、40.74%、71.28%、83.73%。‘黔辣16号’‘辣研102’接种AMF后地上部Cd含量及地上部富集系数显著降低（P＜0.05）。因而，育苗基质中添加AMF对减少辣椒秧苗Cd含量是可行的，其中接种Ri效果优于接种Fm，‘辣研102’接种效果最优。
- Abstract:
- Taking capsicum as test material,six capsicum varieties were bred by adding bacteria agent in the seedling substrate,which was inoculated with Funneliformis mosseae (Fm) and Rhizophagus intraradices (Ri) without inoculating bacteria (CK),to study the effects of arbuscular mycorrhizal fungi (AMF) on the absorption and accumulation of Cadmium (Cd) and growth of different capsicum varieties,in order to provide a reference for realizing the high efficiency and the safe production.The results showed that inoculating AMF promoted the growth of capsicum seedlings,and Fm,Ri improved 13.04%-131.82% and 22.58%-161.11%,respectively,except ‘Qianla 10’.Compared to CK,the aboveground enrichment coefficients of ‘Layan 201’‘Luosijiao XJ-16-9’‘Qianla ‘Layan 101’‘Qianla 16’,and ‘Layan 102’ decreased by 9.19%,4.79%,43.31%,40.74%,71.28% and 83.73% respectively.After being inoculated with AMF,the aboveground Cd content and the aboveground enrichment coefficient of ‘Qianla 16’ and ‘Layan 201’ in Guizhou significantly decreased (P<0.05).Therefore,it was feasible to decrease the Cd content of capsicum seedlings by adding AMF into the seedling medium,and the effect of inoculation Ri was better than that of Fm,and that of ‘Layan 102’ was the best.10’
