Abstract

The global popularity of horned melon highlights the need of sound crop establishment processes, since uniform and quick seed germination has a substantial influence on crop yield and quality. Using a Completely Randomised Design (CRD) with a factorial structure, the effects of hydro priming durations (0, 8, 16, 24, 32, and 40 h) on seeds of two horned melon landrace (L1&L2) were investigated. Hydro priming had significant (P>0.05) influence on several germination indices (germination percentage, relativized percentage, mean germination rate, germination index, synchronization, duration to 50 % germination, mean daily germination, peak value, and germination value). Among the germination indicators tested, landrace (L2) exhibited a considerably stronger germination response than L1. The findings also reveal a curvilinear relationship between priming length and germination percentage, with 24 hours being greatest proportionately. The mean germination rate, germination index, mean daily germination, peak value of germination, and germination value all rose as the hydro priming duration increased. Primed seeds germinated more quickly than unprimed ones. With increasing priming duration, the synchronization index fell linearly. The interaction between landraces and hydro priming was not significant (P>0.05) for final seed germinated, relativized germination, and synchronization indices, but it had a significant impact on all other indices. Because the efficacy of hydro priming tends to lessen with extended soaking, we recommend using it for a maximum of 32 hours. Future study should concentrate on alternative priming chemicals and the applicability of various priming solutions for various agroecosystems
