丛枝菌根真菌对重茬草莓产量和品质的影响 总被引:21,自引:1,他引:20
于日光温室条件下,研究了丛枝菌根真菌Glomusmosseae(Nicol.&Gerd.)Gerd.&Trappe,GlomusintraradicesSchenck&Smith和Glomusversiforme(Karsten)Berch对重茬土壤中草莓生长、结实和品质的影响。结果表明,供试真菌在同一时期的侵染率不同,同一菌种在不同时期侵染率有较大区别;无论土壤消毒与否,它们均可促进草莓的生长发育,提早开花4~12d,显著提高草莓单果重、单株果数和单株产量,单株产量提高27.6%~39.5%,提早4~6d成熟,而且有利于草莓前期产量的形成。接种处理还提高了草莓果实中维生素C和糖的含量,降低了可滴定酸的含量,改善了草莓果实品质。其中以Glomusversiforme接种效应最大。 相似文献

森林草莓独脚金内酯合成关键基因D27的克隆与表达分析 总被引:2,自引:0,他引:2
根据森林草莓中独角金内酯合成过程中的关键基因D27的序列信息设计引物,获得了D27基因的完整开放阅读框架。采用MEGA5.0软件,对森林草莓与其他物种D27基因编码的氨基酸序列进行聚类分析,发现森林草莓D27基因与其他物种D27基因具有较高的同源性。设置正常供磷、缺磷和在缺磷条件下接种丛枝状菌根真菌处理,利用电感耦合等离子发射光谱仪测定草莓植株的磷含量,结果表明缺磷条件下接种丛枝状菌根真菌,草莓植株中磷含量极显著提高,而缺磷处理的磷含量极显著降低。实时荧光定量PCR结果表明,与正常供磷处理相比,缺磷和接种丛枝状菌根真菌处理条件下,D27基因的表达量分别上调7倍和11倍,这说明D27基因的表达既受到磷水平调控,又受到菌根形成的调控。 相似文献

The application of arbuscular mycorrhizal fungi (AMF) in strawberry cultivation can improve its growth and development. The objective of this study was to evaluate if strawberry plants in the absence and presence of inoculation with AMF communities, obtained from soils collected in reference-sites in the cultivation of this species, differ in their morpho-horticultural performance. Two experiments were carried out: in experiment I (frequency of AMF communities species) the treatments were eight soils containing AMF communities, collected from natural and agricultural ecosystems in reference-sites of strawberry cultivation in southern Brazil, with nine samples per treatment; in experiment II (use of AMF communities in strawberry) the treatments were eight AMF communities and one control (non-mycorrhizal plants), arranged in a completely randomised design, with three replicates. The species Claroideoglomus aff. luteum, C. claroideum, C. etunicatum, Funneliformis mosseae and Glomus sp2 were the most frequent in the studied sites and the morpho-horticultural performance of strawberry plants was improved when plants inoculated with AMF communities. Strawberry plants inoculated with mycorrhizae develop a more profuse root system and fruit anthocyanin content is increased. 相似文献

以“章姬”“京藏香”“京桃香”3个品种的草莓为试材,采用盆栽试验的方法,研究接种丛枝菌根真菌(arbuscular mycorrhiza fungi,AMF)摩西斗管囊霉Funneliformis mosseae、根内根孢囊霉Rhizophagus intraradices、植物根围促生细菌(plant growth-promoting rhizobacteria,PGPR)PGPR 5-1和PGPR PS1-1菌株对草莓生长、产量和白粉病的影响。结果表明:AMF+PGPR处理的AMF侵染率、丛枝着生率和泡囊数均大于单接种AMF处理,表明PGPR菌株能够促进AMF的侵染和根内扩展;AMF+PGPR组合促生防病的效应大于任一单接种处理。其中,Fm+PS1-1和Fm+5-1′组合促生、增产和控制白粉病的效果最好。“章姬”草莓的接种效应大于其它2个品种的接种效应。Fm+PS1-1处理显著增加了“章姬”草莓的单株花蕾数、单株开花数、单株结果数和单株产量,单株产量最高达到75.8g,而白粉病的病情指数最低。可知,Fm+PS1-1和Fm+5-1′为最佳组合,对促进草莓高效高质绿色生产具有较大的应用潜力和研发前景。 相似文献

The influence of arbuscular mycorrhizal fungi (AMF) colonization on free amino acid concentrations in strawberry (Fragaria × ananassa Duch., cv.Nohime) plants was investigated using two AMF species [Glomus mosseae (Gm), Gl. aggregatum (Ga)] under phosphorus-supplemented (+P) or non-supplemented (−P) conditions. Ten weeks after AMF inoculation, mycorrhizal plants showed higher values in dry weight of both shoots and roots than did non-mycorrhizal ones among most of the treatments. Shoots and roots of mycorrhizal plants had greater phosphorus concentrations in −P plots, while in +P plots, P concentrations differed little among the inoculation treatments. AMF colonization was greater in plants inoculated with Gm than in plants inoculated with Ga. Total amino acid concentration was higher in most of the plants inoculated with Gm than in non-mycorrhizal ones regardless of P treatment. Serine, glutamic acid, glycine, alanine, leucine and GABA were higher in both mycorrhizal plants in −P plots than in non-inoculated plants. In +P plots, threonine and isoleucine concentrations were greater in both mycorrhizal plants than in non-inoculated ones. Asparagine, glutamic acid, glycine, citrulline, GABA and arginine were greater in plants inoculated with Gm than in non-mycorrhizal ones. These findings verified that inoculation with AMF increases total amino acid concentrations and concentrations of specific amino acids in strawberry plants with or without phosphorus supplementation, though the effects varied with species of mycorrhizal fungus. 相似文献
