| Abstract | ||||
| The paper aimed to determine the changes that occurred in germination characteristics, agronomic traits and enzymes activity of lupine after pre-sowing treatments. The present study analyzed the influence of six seed treatments by seed priming and coating on yield of Egyptian commercial variety of lupine (Giza 2). Laboratory, greenhouse and field experiments were conducted at Agricultural Research Center (2022/2023 and 2023/2024 crop seasons) in a randomized complete blocks design with three biological replications. Aqueous solutions of K2SO4 (0.5 g/ml), salicylic acid (0.1 g/ml), MgSO4 (0.5 g/ml) were prepared, Extra Seed Power priming (0.3 g/ml) were used to prime seeds by soaking for 8 hours, while Extra Seed Power coating was used as a powder, which was mixed with seeds before planting. Results showed that the treatments differed significantly for all the studied traits. ESP priming and ESP coating followed by MgSO4 (0.5 g/ml) and K2SO4 (0.05 g/ml) had higher values in different germination and seedling traits under study. Data indicated that the yield characters improved by treated seed as compared with untreated seed under field conditions. The Extra Seed Power priming (0.3 g/ml) gave higher values for most yield characters followed by ESP coating, while salicylic 0.1g/ ml gave lower values. Treating seeds with ESP prime and ESP coat considerably increased the amount of peroxidase, catalyze and amylase in germinating seeds, compared to other treatments and control. Most of the evaluated parameters were had strong positive correlations among some studied traits, except, first height node and seed index which had negative correlation with all characters, according to phenotype correlation coefficient analysis. This study suggests that Extra Seed Power as priming at 0.3 (g) concentrate and Extra Seed Power as a coating were suitable treatments and highly responsive that can enhance germination of seeds, stimulate seedling development and give higher yield in lupine under Egyptian environmental conditions. | ||||
