Several priming treatments have been used to increase germination, improve germination uniformity and seedling establishment under stressed conditions. A study was conducted to determine the impact of two priming techniques (hormonal priming and hydro-priming) on seedling growth and seed germination of Cucurbita pepo treated with different concentrations of mercury (0, 200, 500, 1000 and 2000 µM). Seeds of Cucurbita pepo were soaked in aerated solution of gibberellic acid, 2 mM (hormonal priming) and in distilled water (hydro-priming). The results show that the addition of Hg at 200, 500 and 1000 µM in the medium did not have a significant effect in the growth of no priming seeds of Cucurbita pepo. The phytotoxic effect of mercury on seedling dry weight was observed at high concentration, 2000 µM. Hydropriming and hormonal priming with gibberellic acid improved the seedling dry weight, the tolerance index and the T50 either in seeds of Cucurbita pepo treated or no with Hg. Similarly, results show that the hormonal priming induced by gibberellic acid enhanced the germination percentage of Cucurbita pepo as compared to hydro-priming seeds. It is recommended that hydropriming and hormonal priming be used as suitable priming techniques to enhance cucumber seed germination and tolerance on stress exposure.
