Effect of vesicular - arbuscular mycorrhizal (VAM) fungi on some characteristics of sorghum cultivars

Although plants are always in threat by different elements but natural factors like microorganisms could be there saver in deferent conditions. as today using mushroom coexistence like mycorrizal white different plant weeds play a vital role in agricultural ecosystems. the special characteristics of micoriza mushroom like less expectations and plant resistance to steers factors courses the scientists to have in mind the use of it in stress environments. therefore for study purposes of the different effects of mycorrhizal incolution variation in the growth characteristics of some variation of sargom, an experiment using factorial system white complete blacks and randomness white four repetitions was done in Sistan Agricultural Research Center in sparing of 2007.hand planting was done in lines, theharvest and nersue work was done in the custom of the area and characteristics of the revenue and elements where measured. at the End the data was logic Ted using MSTATC Software. the results show that most characteristics that where tested coexistence of micoriza and variations has great meaning and the best results where in GOETANICATUM & KGS 29 in all of the variations been studied. Also the results showed that there is significant differences between cultivar of sorghum and using mycorrhiza on plant height, number of seed in spike, biomass, root colonization also the result indicates that in order augmentation of plant growth and crop yield it is necessary to choose the most effective fungus species. But. G. etunicatum species were best mycorrhiza strains among other administered ones.
