| Abstract | ||
| The study was conducted to determine the effect of using Rhizobium incculation (0, 20, 40 g kg" seeds) and J3-sitosterol (0, 10, 20, 40 mgL") on nodes number/plant, root and shoot mass, biochemical contents of roots, leaves and seeds of soyb-ean (Glycine max L.). These treatments or their interaction revealed significant improvement on the studied characters. Node number per plant significantly increased by Rhizobium inoculation (20 gkg") at flowering stage or J3-sitosterol (40 mgL") at vegetative stage. A combination of Rhizobium inoculation (20 gkg·1) and p-sitosterol (20 mgL·1) resulted in significant increases in node number per plant at vegetative and flowering stages. Rhizobium inoculation (20 gkg·1) or J3-sitosterol (40 mgL·1) caused the highest effect on fresh and dry mass for root and shoot per plant. However, the maximal seed yield per plant was obtained in response to 10 mgL" J3-sitosterol. Also, the interaction between Rhizobium inoculation (40 g kg·1) and J3-sitosterol (40 mgL·1) resulted in the maximal values of root and shoot mass at seed filling stage, which led to significant increase in pod number per plant. Total sugar content in the roots and leaves were increased in response to Rhizobium inoculation (40 g kg") or J3-sitosterol (40 mgL·1) as well as when both treatments used together. However, biochemical contents such as free amino acids, protein phenols and indoles were floaculated within and between roots and leaves of soybean, which led to varied seed biochemical contents. | ||
