Phytochemical analysis of canola (Brassica napus L.) Cultivars: Mitigating lead stress effects through the foliar spray of potassium chloride

In the Botanical Garden and Research Laboratory of Institute Pure Applied Biology, Bahauddin Zakariya University, Multan (Pakistan) current work was performed to examine effect foliar spray potassium for lessening toxicity heavy metal in three varieties Canola (Brassica napus L.) viz; Exceed, Cyclone Legend. Seeds were grown pots. They arranged a Completely Randomized Design (CRD). When seeds germinated, some kept without treatment (control) others treated with 15mg/kg 30mg/kg Lead along Potassium spray. Plants harvested subjected phytochemical studies. The role studies (alkaloid, flavonoid, phenolic) showed an increase response against stress. While plants revealed decreased both Pb K expressed lesser compared only metal. This study sheds light on effectiveness improving growth dealing stress decrease harmful metals. However, further are required identify mechanisms mediated alleviation other Keywords: Alkaloid; Canola; Lead; Potassium; Phytochemicals
