The Effects of Time of Scion Defoliation and BAP on the Successful Top Grafting of Durian (Durio zibethinus Murr.)

Abstract

This study aimed to examine the effect of time scion defoliation before cut/being used and the addition of BAP on the success of durian top grafting. The research was carried out in November 2021 to February 2022 in Selopuro Village, Lasem District, Rembang Regency, Central Java. The research design used a 3x4 factorial design on the basis of Completely Randomized Design (CRD) with 3 replications. The first factor was the difference in time of scion defoliation such as, D0: scion defoliation on the day of grafting, D1: scion defoliation 3 days before grafting, D2: scion defoliation 6 days before grafting, D3: scion defoliation 9 days before grafting. The second factor was the concentrations of BAP such as, B0: (0 ppm), B1: (30 ppm), B2: (60 ppm). The data was analyzed using ANOVA (Analysis of Variance) and further test with Duncan Multiple Range Test (DMRT) at the level of five percent (5%). The results showed that the treatment for the scion defoliation 6 days before grafting gave the different results on the parameters of the number of buds, bud length, numbers of leaves, leaf length, and bud breakage time of top grafting durian. The addition of BAP did not affect the durian top grafting
