Abstract: (1600 Views)
In order to investigate the effect of phosphate biofertilizer on physiological and growth characteristics of tall fescue in different salinity conditions, a factorial experiment was conducted in a randomized complete block design with three replications. The results of analysis of variance showed that interactions between salinity stress and biofertilizer were significant on leaf area, total chlorophyll, sodium, potassium, and catalase activity. However, the interaction between these treatments was not significant in the traits such as aerial and underground biomass, chlorophyll a and b, and carotenoids at 5% level. The maximum leaf area and total chlorophyll content in biomass was 1 g / L and control salinity and the highest catalase activity, assessment in 0.5, 1 g / L biofertilizer treatments and 12 ds / m salinity. The highest amount of sodium was observed in the treatment without biofertilizer and 12 dS / m salinity. Also, the highest potassium content was observed in non-fertilized treatments and 0.5 g / L biofertilizer with control salinity without fertilizer and salinity of 12 dS / m. Significant difference between plants treated with biofertilizer in salinity conditions indicates improvement of tall fescue function in stress conditions. In general, the results of this study indicate that tall fescue treatment with bio-phosphate fertilizer has positive effects on plant growth and physiological characteristics.
