Foliar Application of Gibberellin Alleviates Adverse Impacts of Drought Stress and Improves Growth, Physiological and Biochemical Attributes of Canola (Brassica napus L.)

Under the current climate change scenario, water stress is one of key factors that reduce production crops. Gibberellic acid (GA3) an efficient endogenous plant hormone shows a vital role in growth and development. Production canola (Brassica napus L.) its oil contents are severely affected under drought stress. The present study was conducted to investigate potential GA3 alleviating canola. Three levels (G0 = 0 mg L−1, G1 100 G2 150 L−1) as foliar applications were applied two drought-stress conditions (D1 for three days D2 six stress) on varieties (Punjab Faisal canola). Irrigation after 3 weeks germination, while application done at intervals 4 5 germination. When comparing output all treatments, it noticed G0 L−1 (control plants), water-stress markedly reduced seed but increased protein linoleic acid. With maximum values height (90.83 cm), no. siliqua plant−1 (15.50), siliqua−1 (15.55), length (5.08 relative (77.60%), yield (0.46 g), chlorophyll (0.62), carotenoid (39.52), oleic (60.20) recorded Based these results, concluded adverse effect different parameters could be ameliorated by exogenous through dose L–1. Moreover, same treatment improves quality parameters, i.e., oil, obtained from
