【 摘 要 】
The study describes the impact of microwave radiation on the germination rate and growth of Abelmoschus esculentus (L.) Moench (okra). The two okra varieties, viz. Meenaxi-371 and Soniya-1402, were used for the experiment. Their seeds were exposed to 0–14 h (h) of microwave radiation (9.3 GHz). Non-irradiated seeds (0 h exposure) served as control. We found that microwave radiation on seeds resulted in an increase in their germination indices and also stimulated the concentration of β-1,3-glucanase enzyme. The results also indicate a remarkable increase in bioactive compounds such as flavonoids, polyphenols, carotenoids, chlorophyll, lutein, protein, and β-carotene in okra seedlings exposed to 8–10 h of radiation. A further dose escalation in the microwave radiation caused a decline in the germination and growth of the okra plant. The expression level of ACS4, ETR2, and ACS6 showed up-regulation under the influence of microwave irradiated conditions. Therefore, it is evident that a well-controlled and defined irradiation has the potential to enhance the overall growth and yield of selected okra varieties.
