Phytohormone signalling and cross-talk to alleviate
Aluminium (Al) is one of the most abundant metals in earth crust, which becomes toxic to the plants growing in acidic soil. Phytohormones like ethylene, auxin, cytokinin, abscisic acid, jasmonic acid and gibberellic acid are known to play important role in regulating Al toxicity tolerance in plants. Exogenous applications of auxin, cytokinin …

Flotation technique: Its mechanisms and design parameters
In the Jameson cell slurry and air are introduced at the top which proceeds downward in the downcomer and forms a liquid jet. Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …
