摘要:
发根农杆菌(Agrobacterium rhizogenes)在促进植物根系生长方面具有重要意义,而绿色木霉(Trichoderma viride)在抑制致病菌、促进作物生长等方面效果显著。为探讨发根农杆菌和绿色木霉对玉米根系生长的影响,明确二者协同增效效果及作用机制,采用盆栽法,设置发根农杆菌与绿色木霉2类菌株单一、复合接种作为试验组,以不施菌剂作为对照,共4组处理。测定接菌后玉米株高、茎粗、叶宽、叶绿素含量、根系指标等,探究菌剂单一处理、复合处理对玉米生长的促进效果。结果表明,菌剂复合处理与单施发根农杆菌、单施绿色木霉相比玉米生长指标明显提高;单施发根农杆菌、绿色木霉与对照相比根系生长差异明显,单一施加发根农杆菌、绿色木霉以及混合处理均可以显著提高玉米植株茎粗和叶绿素含量(SPAD值),但各试验组间均无显著性差异。说明3种处理均能促进玉米根系生长,但复合处理对玉米根系生长促进作用优于发根农杆菌和绿色木霉单一接种,说明玉米植株根系生长过程中二者可以起到协同促进作用。
