NaCl胁迫下促进加工番茄生长的AM真菌筛选

目的]筛选出有效提高加工番茄抗盐性的丛枝菌根真菌.方法]在温室盆栽试验条件下,分别接种Glomus mosseae、G.versiforme、G.intraradices和G.etunicatum 4种AM真菌并设计了无盐和0.3; NaCl胁迫处理,测定接种4种AM真菌对加工番茄幼苗株高、单叶叶面积、叶绿素含量、湿重、干重、地上部和地下部N、P元素含量生长效应指标.结果]在0.3; NaC1胁迫条件下,对加工番茄促生效应最好的是G.mosseae和G.versiforme.接种后加工番茄植株单株干重比对照增加65;和60;；地上部N含量比对照提高了66.48;和40.54;,地上部P含量比对照提高了69.76;和79.06;.结论]G.mosseae和G.versiforme接种加工番茄可有效提高加工番茄的耐盐性,具有较好的应用前景.

Screening the AM Fungus Which Promotes the Growth of Processing Tomato under NaCl Stress Conditions

【Objective】To screen the arbuscular mycorrhizal fungus strains which can improve processing tomato salt resistance.【Method】Processing tomato seedlings were inoculated with 4 different AM fungus (Glomus mosseae,G.versiforme,G.intraradices and G.etunicatum) under salt - free conditions and salt stress conditions(0.3%NaCl) in pots,then the growth effects of the AM fungus that can enhance the processing tomato seedlings plant height,single leaf area,chlorophyll content,wet weight,dry weight,and shoots,roots N,P content were measured.【Result】The result show that G.mosseae and G.versiforme were the best strains for processing tomato growth,which increased dry weight by 65%,60%,the N content of shoots was increased by 66.48%,40.54%,the P content of shoots were increased by 69.76%,79.06%over the control.【Conclusion】G.Mosseae and G.versiforme could effectively improve salt tolerance of processing tomato,which suggested the two AM fungi strains may be potential in processing tomato culture.
