تاثير مايه زني توام باكتري BACILLUS SUBTILIS و قارچهاي اندوميكوريز بر رشد و عملكرد نهال بسته PISTACIA VERA L

The interactive effect of co - inoculation Bacillus subtiiis and vesicular-arbuscular mycorrhizal fungi (VAM) on growth and mineral nutrition of Pistacia vera L. was evaluated in a green - house experiment. inocula consisted of VAM fungi and a rhizobacterium (Bacillus subtiiis). This rhizobacerium behaved as "Mycorrhiza helper bacteriumʹ1 promoting establishment of The introduced VAM endophytes. Dual inoculation with VAM fungi and B. subtiiis significantly increased biornassand nitrogen (N) and phosphorus (P) accumulation in plant tissues. The inoculated rhizobacterium may have released phosphate ions which were effectively taken up by external VAM mycellium. It appears that mycorrhizosphere interactions between bacterial and fungal plant associated promote a sustainable nuirient supply lo plants.
