Abstract

In our investigation, effect of auxin on rooting and sprouting behavior of stem cutting of Excoecaria agallocha has been studied. Initially stem cuttings was pretreated to remove the phenol content in the cutting and then the stem cuttings that was devoid from phenols cuttings were subjected to hormonal treatment with auxins derivatives as IBA 2000ppm, IPA 2000ppm, NAA 2000ppm and IBA+NAA combination 2000ppm. The root length and their number, rooting and sprouting percentage, number of leaves per cutting, leaf area and photosynthetic pigments were analyzed on 40, 50 and 60 day after planting(DAP) and isoenzyme pattern of peroxidase of root and leaf were also analyzed. Among the auxin treatments IBA 2000ppm vastly enhances rooting and sprouting behavior followed by IPA, IBA+NAA and NAA of Excoecaria agallocha. The isoenzyme analysis for peroxidase were clearly shown that peroxidase (POX) were highly supports both root initiation and elongation processes in Excoecaria agallocha L.
