In this work we investigated whether priming with auxin, cytokinin, gibberellin, abscisic acid and ethylene, alters the physiological responses of seeds of pigeon pea germinated under water and cadmium stress. Seeds treated with water or non-treated seeds were used as control. Although compared to non-treated seeds we found that the hormone treatments improve the germination of pigeon pea under cadmium stress, however, these treatments did not differ from water. However, we also observed a trend of tolerance to the effects of cadmium in the presence of ethylene, suggesting that the use of this hormone may be an efficient method to overcome seed germination under metal stress.
在这项研究中，我们调查了用生长素、细胞分裂素、赤霉素、脱落酸和乙烯引发是否会改变木豆种子在水分和镉胁迫下萌发的生理反应。用水处理的种子或未处理的种子用作对照。虽然与未处理的种子相比，我们发现激素处理提高了木豆在镉胁迫下的发芽率，然而，这些处理与水处理没有差异。然而，我们还观察到在乙烯存在下对镉影响的耐受趋势，这表明使用这种激素可能是克服金属胁迫下种子萌发的有效方法。
