Sulphur amino acids and free amino acids in cotyledons of germinated seedlings ofAlbizzia lebbeck Benth exposed to different light intensities

Abstract

Metabolism of sulphur amino acids and free amino acids has been studied in the cotyledons during germination ofAlbizzia lebbeck Benth seeds under different light intensities. Seeds ofA. lebbeck contain a large amount of sulphur amino acids which are rapidly utilised during early stages of germination A similarity in the distribution pattern of amino acids in cotyledon samples raised from different seed stocks is noticed. The level of amino acids was higher in the illuminated samples as compared to dark controls. The higher concentration of asparagine, and SAAII during the seedling growth with the increase in light intensities compared to dark-grown seedlings as well as initial seed sample may indicate the involvement of light-triggered reactions in the synthesis of these metabolites.
