Induction of Osmoregulation and Modulation of Salt Stress in Acacia gerrardii Benth. by Arbuscular Mycorrhizal Fungi and Bacillus subtilis (BERA 71)

Table 1

Effect of salinity stress (250 mM NaCl) on intensity of structural colonization (%) of arbuscular mycorrhizal fungi (AMF) as mycelia (M), vesicles (V), and arbuscules (A) in Acacia  gerrardii in response to endophytic B. subtilis (Bs). Data presented are the means ± SE ().
