Fig. 7From: A novel rejuvenation approach to induce endohormones and improve rhizogenesis in mature Juglans treeIntegrated optical density (IOD) changes in rejuvenated and mature soft shoots. Rejuvenated soft shoots (a, c, e, g) and mature soft shoots (b, d, f, h) reflect changes in IAA, ABA, GA3 and ZR levels during ARF.
