Abstract
Plants are capable of synthesizing β-carotene but unfortunately humans are not able to do so. However, they are capable of
converting β-carotene absorbed from their diets to vitamin A. Hence, an increase in β-carotene content in plants can be an
alternative to increase the vitamin A content & prevent from certain diseases content in diet of individuals. Therefore, foliar application of amino
acid solution is a technique used for investigating the effect of amino acid supplementation on enhancement of beta carotene content in green leafy
vegetables.
In this study, fenugreek (Trigonella foenum graecum) seeds are treated with proline, tyrosine, tryptophan and proline, tyrosine, tryptophan
combination (1:1:1). It was observed that growth and beta carotene content were higher in the treated plants. Exclusive treatment with Proline,
tyrosine and the tryptophan resulted in an increase in growth and beta carotene content when compared to control which is lesser than that of
proline-tyrosine-tryptophan combination treated seeds.
