Abstract
The effect of auxin synergists viz., para hydroxy benzoic acid (PHBA), rutin, morin and
phloroglucinol (PG) at 2000 ppm alone and in combination with IBA 2500 ppm on rooting and root
characters of fig hardwood and semi hardwood cuttings were evaluated. The results of this study
clearly demonstrated that the hardwood cuttings recorded superior to semi hardwood cuttings for all
the parameters taken. Among the treatments IBA 2500 ppm + PHBA 2000 ppm recorded highest
percentage of rooting, more number of roots per cutting, longest root length per cutting and maximum
survival percentage in both hardwood and semi hardwood cuttings. When auxin synergists were used
alone could not induce effective rooting, but when used in combination with IBA; PHBA, rutin and
morin showed synergistic effect on rooting and other root characters. However, PG showed antagonistic
effect with IBA. The interaction effect between type of cutting and treatments showed that hardwood
cutting treated with IBA 2500 ppm + PHBA 2000 ppm showed significant superiority in respect to
percentage of rooting and other root characters over other treatments.
