Abstract:

Zea mays L. dihybrid 204 plants were grown in steam sterilized sand culture under greenhouse conditions and treated either with full strength Hoagland's nutrient (control) or control plus 35, 70, 105 mM NaCI. The seedlings were either inoculated or not inoculated with Streptomyces atroolivaceus. Fresh and dry weights of shoot and root were significantly higher in the inoculated than the non-inoculated plants grown under saline conditions. Chlorophylls and total pigments were proportionally increased by increasing NaCI and the increase was mainly due to Chl a. Inoculation of 70 and 105 mM NaCI- treated plants decreased the pigments content compared to the non- inoculated. Shoot protein was significantly enhanced by inoculation under saline conditions. Enhancement of dry matter and protein content and decrease of pigments were directly or inversely proportional with the population of the experimental organism in the rhizosphere and soil of Zea.
