ENHANCING ROOTING PERFORMANCE OF STEM CUTTING OF GARDENIA (Gardenia jasminoides) USING ROOT PROMOTING TREATMENTS

Abstract

The experiment was conducted with Gardenia jasminoides to find out the suitable root promoting treatments of stem cutting both in the winter and summer season. The treatments of the experiment were

T 0 = Control, T 1 = Mixed plant growth regulators (1000 ppm IBA + 1000 ppm NAA), T = Wounding to cutting base and T = Wounding to cutting base + Mixed plant growth regulators. The experiment was laid out in Randomized Complete Block Design with three replications. Among the treatments, T 3 was found superior in terms of days required for shooting, number of roots per cutting, number of shoots per cutting, percentage of rooting, percentage of survival, etc, both in the winter and summer season. The results of T 3 were closely followed by T 1 and T 2 . On the other hand, the results from T treatment were found lowest in all parameters. However, 78.33% rooting in the summer and 67.93% rooting in the winter were recorded from T , whereas it was only 43.66% in the summer and 37.66% in the winter for T

0 treatment.
