Mass Spectral Analysis of Rice Leaves

Abstract

Mass spectral analysis of the mineral constituents of the flag leaves of some varieties of rice, Ponni, IR-26, IRRI-50, and TKM-6, which are highly resistant to the brown spot disease Cercospora oryzae and Kanchi, Karuna, Kannagi, and Co-25, which are highly susceptible to the same disease, was carried out. The elements present in the flag leaves of the rice varieties were classified into major elements viz., Si, K, Ca, P, and Mg and microelements viz., B, Na, Al, Cl, Cr, Fe, Mn, Co, Cu, Zn, As, Br, Rb, Sr, Mo, Ag, Ba, and Pb. It is found that the amount of Fe, Ca, Sr, Pb, and Ag is greater in susceptible varieties while the quantity of K is low in these samples.
