Foliar applications of NAA (50 and 100 µg ml−1) to lentil (Lens culinaris Medic) plants reduced stem height but caused increase in number of branches and pods per plant with consequent enhancement in seed yield. NAA Increased total plant dry matter, partitioning coefficents and harvest Index. Seeds harvested from NAA treated plants exhibited altered chemical composition in terms of increased amino acid content and decreased total soluble sugar and starch levels, better germinability, more water imbibition capacity and decreased seed coat thickness. NAA markedly stimulated differentiation of phloem elements in the pedicel. Statistical analysis revealed that NAA also modified the path of influence of various traits In relation to seed yield.
