“…The present study showed that high concentration of KNO 3 reduced shoot length of amaranths and C. gynandra seed. Similar observation by Rahul et al (2020) indicated that seedling length of gray‐leaved saucer‐berry ( Cordia Sinensis Lam.) was reduced by priming in high concentration of KNO 3 .…”

“…It has been highlighted that KNO 3 improved seed germination of pea but this effect depends with the concentration and mode of application (Forti et al, 2020;Matsushima & Sakagamin, 2013;Paparella et al, 2015). Rahul et al (2020) reported that KNO 3 stimulates the germination of seeds by the production of nitrous oxide (N 2 O). N 2 O can increase the germination of seeds and reduce seed dormancy by the regulation of the balance between ABA And GA 3 .…”

“…It was highlighted that inhibitors are leached into the pre-sowing solution by GA 3 (Palepad et al, 2017). Rahul et al (2020) reported that germination of seeds might be improved due to GA 3 treatment through improved synthesis of the hydrolytic enzymes. The hydrolytic enzymes are essential in breaking down the stored food to provide energy that is required for seed germination process (Rahul et al, 2020).…”

The hydrolytic enzymes are essential in breaking down the stored food to provide energy that is required for seed germination process (Rahul et al, 2020). GA 3 promotes germination through enhancing the growth potential of the embryo and overcoming the mechanical barriers imposed by covering layers surrounding embryo (Tuan et al, 2018).…”

The effects of gibberellic acid and potassium nitrate on seed emergence and seedling growth of amaranth and Cleome gynandra were investigated in the greenhouse at Marondera University of Agricultural Sciences and Technology. The study was laid out in a factorial layout within a completely randomized design replicated three times. Potassium nitrate (dry seeds, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, and 1%) and gibberellic acid (dry seeds, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 parts per million) were used, respectively. A total of 100 seeds of both crops were planted in each plastic pocket. Seed emergence percentage and vigor index of amaranth and C. gynandra were evaluated. The effects were more pronounced in seeds treated with gibberellic acid than in potassium nitrate. Seed emergence and vigor index of amaranth and C. gynandra seeds treated with gibberellic acid showed a significant difference at p < 0.01, while potassium nitrate showed no significant difference at p > 0.05. The maximum seed emergence percentage of amaranth and C. gynandra was 67.1% and 64.8%, which was obtained in 2022 and 2021, while the lowest was 35.5% and 37.5%, which was obtained in 2021. The highest vigor index I of amaranth and C. gynandrawas 590.3 and 586.2, which was observed in 2022 and 2021, while the lowest vigor index I was 45.2 and 170, which was obtained in 2021 and 2022. The results obtained indicated that the application of gibberellic acid on seeds of amaranth and C. gynandra can alleviate seed dormancy.
