Response of ‘Bignay’ [Antidesma bunius (Linn.) Spreng] to cutting origins, IBA and BioGroe treatments

The response of ‘Bignay’ [Antidesma bunius (Linn.) Spreng] to the cutting origins and different levels of plant bio-regulators consist of Indole-3-butyric Acid (IBA) and Biogroe treatments were investigated by means of 3 x 9 factorial experiment in Completely Randomized Design (CRD) using an automated mist propagator. Two hundred sixteen (216) healthy seedlings containing 9 nodes each were used in the study. Results revealed that cutting origins significantly increased shoot length but have no influence on the root number, percent rooting and percent survival. The cuttings originated from the bottom portion of the stem recorded the longest mean in terms of shoot length (12.48 mm) including the highest percent survival and percent rooting (82.41%). Highest mean number of roots were observed on the top cuttings (1.93). Indole-3-butyric Acid (IBA) and Biogroe treatments on cuttings have no effects on the different parameters evaluated. The interaction effect between cutting origins and IBA/Biogroe treatments significantly increased the percent rooting and percent survival except the shoot length and root number of Bignay cuttings. Overall, the findings inferred that A. bunius can be propagated by any cutting origin derived from the main stem of the donor plants tested. Cuttings can effectively be induced to produce roots and survive and can be economically mass propagated even without the application of different concentrations of IBA and BioGroe
