Effect of aluminium toxicity on biochemical parameters of rice

Experiment were conducted at Bidhan Chandra Krishi Viswavidyalaya to ascertain the intensity of damage in rice due to aluminium toxicity among the moderately resistant and susceptible cultivar Khitish and Shatabdi, respectively. Changes in respect of protein, free amino acid and changes in root and shoot of the crop had been studied. It was observed that the above parameter decreased substantially with the increase of aluminium i.e. from 0.1 mM to 0.6 mM as also with duration of exposure i.e. from 24 hour to 72 hour. However, the intensity of damage was less in Khitish compared to Shatabdi.
