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.
