ABSTRACT Pinus gerardiana Wall. is a notable nut-producing pine having essential ecological and economically viable forestry species having restricted distribution in Afghanistan. Natural regeneration of the species is either incredibly poor or nonexistent. Due to irregular and uncommon seed years, problems with dormancy, and other factors, this species' natural habitat renewal is slowed down. Therefore, we investigated the effects of sowing media and gibberellic acid on germination and seedling growth of chilgoza pine. The sowing media were categorized into three types with various proportions of soil, sand, and FYM, viz., M1 (1:1:1), M2 (1:1/2:1/2), M3 (1:1/3:2/3), and three GA3 concentrations were used, viz., 0, 50, and 100 mg. L-1, for assessing their influence on germination and seedling growth. It was observed that apart from MGT (42.36 days), the higher FGP (58.66%), GI (274), GRI (75.01), SFW (8.74gr), SDW (4.78gr), SL (219.80 mm), SVI (129192602) were obtained when seeds were initially immersed for 6 h at 100 mg. L-1 GA3 solution and then sown in the medium of equal proportions of soil, sand, and FYM. In terms of simple effects, GA3 concentrations significantly impacted the vegetative growth of seedlings. In contrast, media effects on seed germination were highly significant, meaning that chilgoza seed contains sufficient gibberellin for germination and is reduced during seedling growth stages. The vegetative growth response of the seedling to the concentrations of GA3 had a significant linear response, but the response of FGP and MGT against GA3 concentrations was significantly quadratic, i.e., the use of GA3 concentrations can stimulate the growth of seedlings. The sowing media had a pronounced effect on FGP and MGT due to nutrients and ventilation. The highest concentration of GA3 increased the seedling's vegetative growth, so further use may be necessary over time. It is suggested that GA3 and media may be used to improve chilgoza seed germination and subsequent seedling growth. |
