ABSTRACT

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.

受控的微波辐射对提高南方锥果(L.)Moench生产力的影响

摘要

该研究描述了微波辐射对发芽率和生长的影响黄蜀葵荸荠(L.)门希(秋葵)。两个秋葵品种,即。Meenaxi-371和Soniya-1402用于​​实验。它们的种子暴露于0–14 h(h)的微波辐射(9.3 GHz)中。未辐照的种子(暴露0 h)作为对照。我们发现,种子上的微波辐射导致其发芽指数增加,并且还刺激了β -1,3-葡聚糖酶的浓度。结果还表明,生物活性化合物(例如黄酮类,多酚,类胡萝卜素,叶绿素,叶黄素,蛋白质和β)的显着增加秋葵幼苗中的β-胡萝卜素暴露于8-10 h的辐射下。微波辐射中剂量的进一步增加导致黄秋葵植物的发芽和生长下降。在微波照射条件下,ACS4ETR2ACS6的表达水平上调。因此,很明显,良好控制和确定的辐照有可能增强所选秋葵品种的总体生长和产量。
