    Journal of Global Innovations in Agricultural Sciences, 2023
    Sorghum (Sorghum bicolor L. Moench) seeds were tested to discover how different priming techniques affected their germination rates, a pot experiment was conducted by the combination procedures for seed priming with magnetic fields (magneto-priming) and hormonal priming seed with gibberellic acid (AG3) or ascorbic acid (AsA). Final germination percentage (FGB), mean germination time (MGT), germination rate index (GRI), coefficient of the velocity of germination (CVG), mean daily germination (MDG), peak value (PV), and germination value (GV) are all included as germination metrics. Among the two durations of exposure time to magneto-priming used, the significantly highest FGB, GRI, CVG, MDG, PV and GV were reported in the primed with the time duration 1 h (MP2), significantly lowest MGT for MGT in days. Whereas among the two hormonal primings used, GA3 recorded the highest increases upon the unprimed seeds for FGB, GRI, CVG, MDG, PV, and GV, in addition, significantly lowest MGT for MGT in days. However, when magnetic seed is combined shows the highest increase rates compared to the control treatment for time exposure for 1 h (MP2) with GA3 or AsA in all studied traits, in addition to the lowest rates decrease in MGT. Overall, the findings imply that seed priming by magnetic field and hormone priming via GA3 or AsA may be promising and practical priming techniques because of their favorable impacts on some physiological sorghum characteristics. Keywords: Wheat, physiological parameters, gibberellic acid, UV-C radiation, hydro-priming.

    Two separated sets of laboratory experiments were studied for barley seeds treating using a microwave and ultraviolet irradiation. In the microwave set, seeds have been exposed to the microwave radiations (2450 MHz) for 0 sec (control, MW0), 5 sec (MW1), 10 sec (MW2), and 20 sec (MW3), while in the ultraviolet set, seeds have exposed to UV-C radiation (254 nm) for 0 min (control, UV0), 30 min (UV1), 60 min (UV2), and 120 min (UV3). The aim is to study the influences of different exposure time from MW and UV-C radiation on some barley seed germination parameters and to choose the fitting model Logistic (Log) or Gompertz (Gom) suited to cumulative germination curves under the influence of these factors. The results of this study showed higher seed germination percentage (93.33%) at the exposure time MW2 and UV3 (88.33%), whereas the lowest value (66.67%) recorded in MW3 treatment. The results also appeared the best values at MW2 in SG, 6.24 seed day-1; in GRI, 31.19% day-1, and in GI, 87.67, as well as at UV2 in MGT, 3.32 day. The higher value of asymptotic germination barley seeds was found with Gom function (97.24%, and 88.71%) at MW2 and UV3, respectively. Besides, Gom functions at MW1 and UV2 give the highest maximum germination rates at 2,08 and 2.51% h-1, respectively. The results of the Log equation illustrated the highest value of germination percentage of the inflection point has recorded in 43.85 and 47.37 % on UV3 and MW2 treatments, respectively. For the fitting growth curve, the results have proven that the Gom function was shown the lowest values in MSE in all MW and UV exposure times, as compared with the Log function. So, the results of the Gom function were more fit for the growth curve for MW and UV treatments, as compared with the Log function.
