To study the effect of plant growth regulator and chemicals on survival of cuttings in fig (Ficus carica L.) Cv.Dinkar.

Abstract

The present investigation entitled Studies on Effect of Chemicals, Plant Growth Regulator on Growth and Survival of Cuttings in Fig (Ficus carica L.) Cv.Dinkar was conducted at section of Horticulture, College of Agriculture, Badnapur, during 2019-20. The experiment was laid out in RBD with fifteen treatments replicated twice. The effectiveness of IBA, SA and PHB concentrations, in which IBA applied as solo and combined with all chemical concentrations, and control were tested for their ability to enhance rooting frequency (%) of Cv.Dinkar of fig cuttings. Among the chemical treatments Auxin concentrations tested ranged from 1000 to 1500 ppm IBA. However 1500 ppm IBA induced significantly greater rooting percentage than the control, but no single auxin, auxin concentration or combination of auxins was clearly superior in every study. IBA application also enhanced the number of roots developed on each cutting. In Present experimentation, maximum length of longest root (T14 34.49 cm) which is observed with IBA + Polyamine, average root length (26.93 cm), diameter of root (1.85 mm), volume of root (9.39 ml), fresh weight of root (9.53 g), dry weight of root (4.97 g) was noticed in treatment T14 (T2 + Putrescine 3.0 mm). While minimum length of longest root (12.68 cm) in control, average root length (9.13cm) diameter of root (0.77 mm), volume of root (1.85 ml), fresh weight of root (2.02 g), dry weight of root (0.34 g) was recorded in treatment Tl5 (control). In present investigation, maximum root: shoot ratio on fresh weight basis (0.29) was noticed in treatment T1 (Indole Butyric Acid 1000 ppm), however minimum root: shoot ratio on fresh weight basis (0.14) was observed in treatment Tl5 (control), while maximum root: shoot ratio on dry weight basis (0.19) was noticed in treatment T5 (T2 + PHB 1500 ppm), while minimum root: shoot ratio on dry weight basis (0.04) was observed in treatment Tl5 (control).
