“…), biosynthesis of cell wall, chlorophyll, vascular bundle differentiation, pollen tube growth, microtubular organization, transport of assimilates from one part to another etc. These functions of BR improve anti-oxidative defence system of plants and enhance bio-synthesis of total proteins, nucleic acid, photosynthesis that finally growth and yield of plants (Haubrick and Assmann, 2006, Hayat, 2010and Hola, 2011, Biesaga et al, 2014. BR is superior to IAA in significantly effecting higher growth and yield of Indian mustard due to higher chlorophyll content, photosynthetic rate and carbonic anhydrase activity (Hayat et al, 2001).…”
