3.4 Total soluble carbohydrate content
Water stress exhibited a significant increase in TSC content. The enhancement of the TSC content coincided with the decrease in oil content (Fig3). Presented results showed that drought stress increased TSC content by 52.3% and 46.6% in B0D2 and B1D2 respectively. Also, results showed that PGPB treatment merely in mild stress (75% FC) increased in comparison with its parallel level in water stress.
