Application of Biocat G, Selenium, and Chitosan to Counteract the Negative Effects of Cd in Broccoli Plants Grown in Soilless Culture

The accumulation of cadmium in plants produces phytotoxic damage and a decrease crop yield. To avoid this effect, it is necessary to prevent its absorption by roots reduce toxicity plant tissues. current study was aimed evaluate the effect exogenous applications Biocat G (fulvic/humic acids), selenium (Se), chitosan leaves broccoli exposed Cd stress. applied treatments were: (i) T1: Hoagland nutrient solution (NS), (ii) T2: NS + at 3 mg L-1 (NS Cd), (iii) T3: root application BioG), (iv) T4: foliar Se Se1), (v) T5: Se2), (vi) T6: chitosan1), (vii) T7: chitosan2). results showed that (T3 T5) ameliorated adverse effects caused significantly improved growth rate decreasing toxicity; besides, able limit transport from inflorescences, reducing content edible part. These yielded best results, act on deactivating toxicity, but they did not affect tissue. In addition, limits non-edible
