Preliminary study on the effect of iba on the cuttings of Bambusa vulgaris Schrad. Ex J.C. Wendi

Abstract

This study investigated the effect of IBA on the sprouting and growth of Bambusa vulgaris cuttings. Forty (40) culm cuttings of two nodes per cutting were divided into four (4) batches with each batch containing ten (10) cuttings. Each batch was subjected to one hour (60min) soaking in Indole Butyric Acid (IBA) Treatment as follows; T1 soaked in 300ppm, T2 in 400ppm, T3 soaked in 500ppm and T4 was the Control (cuttings were not soaked in IBA). After the soaking operation, the cuttings were injected with 5ml of the same treatment used for each batch and were tapped to avoid leakage. The experiment was laid out in a Completely Randomized Design (CRD) with four treatments replicated. Data were collected weekly for 6weeks.The results revealed thatthe cuttings without the application of growth regulator performed better in terms of height and collar diameter compared to the cuttings that were treated with theregulator. Number of leaves and sprouts produced in all treatments were not significantly different from each other. Thus, it can be recommended that B. vulgaris can be vegetatively propagated without IBA application.Keywords: Bambusa vulgaris, Vegetative propagation, Plant growth regulator, Cuttings
