The influence of mycorrhizae on pea yield and quality in drought caused stress conditions

摘要: Mycorrhizas are associates of fungi, representatives Zygomyceta, Basidiomyceta and Ascomyceta living on the higher plant roots. Mycorrhizal fungi fossil residues were found roots first vascular plants derived from Devon period approx. 400 mil. years B. C. Botanists think that this symbiotic association played an essential role in developing spreading earth. However, regardless their effect development mycorrhizal affected soil development. They produce humous components organic sticky substance (extra-cellular polysaharides) hold into aggregates resulting a well structured good porosity large mycorrhizas intake total microbial bio-mass. These colonize about 90% plants. The between is highly-interrelated whereby benefit symbiont whereas gets photosynthesis-formed carbon compounds. Owing to dense hyphas network interweaves volume, effective root absorption zone increases via hyphas. also extracts chemical agents, thereby, making available elements such as phosphorus, iron, zinc, copper, boron, otherwise presented low concentrations soluble form. antibiotics protecting parasitic nematodes owing hypha around root, protected against parasites. Mycorrhized more resistant drought-caused stress, have better adequate system tissue Due aforesaid, dry conditions characterized by having survival percent yield compared non-mycorrhized ones. Thanks traits symbiosis all benefits possessed mycorrhized non-mycorrhized, agricultural production does not rely only indigenous strains these but inoculation seedling seed done compatible strain fungi. Inoculation treatment or wet one way inoculum suspended water prior (similar legume with bio-preparations nodule bacteria). This procedure capable for ensuring reducing mineral fertilizer pesticide requirements being very important economical ecological aspect.
