Foliar application of amino acids and fruit peel extracts is likely to resppnd towards improved genetic expression through expression of potential crop yield ....
It is not possible to say at this stage. It depends on a lot of factors like plant stage, environmental factors, absorption, type of amino acids and their mode of application.
When absorbed, some amino acids play a role in activating or repressing some genes. It is advisable to go for a qPCR assay with the housekeeping genes as reference to check the relative expression of target genes.
