Chickpea Seed Proteins as Affected by Mineral Supply Levels

Abstract

Accumulation of different protein fractions in chickpea seed harvested from plants grown under four concentration levels (0, 25, 50 and 100 mM) of sulphur, nitrogen, potassium and phosphorus has been studied. Whereas globulins showed an increase with the increasing concentration of all the four minerals, albumins increased under sulphur, nitrogen and potassium, and glutelins increased under potassium and phosphorus. An increase in nitrogen regime led to increased contribution of tryptophan in the seed protein due to albumins and globulins and methionine contribution due to albumins, globulins and glutelins. Under higher supplies of sulphur, relative contribution of tryptophan due to albumins and methionine contribution due to albumins and globulins had increased.
