Correlation between carbohydrate content, protein, and fat with compatibility of durian seed grafting (durio zibethinus. Murr)

Abstract

Durian nurseries can be done using generative and vegetative material sources. Both sources of propagation have their respective weaknesses and strengths. To get quality seeds requires a combination of two sources of propagation material that has each of the advantages that can complement each other. The process of merging can be through grafting. The grafting method in durian nurseries can use side grafting and shoot grafting methods. The purpose of this study was to determine differences in levels of protein, carbohydrates, fats, and phytohormones from various sources and storage time of the stem. This study was compiled based on factorial designs in the Randomized Group Design (RCBD). The first factor is the source of the stem (S), which consists of 3 sources, namely the primary branch (S1), secondary branch (S2), tertiary branch (S3). The second factor is the length of storage of the stem (T) which consists of 4 levels of storage time of the scion namely: 0 days (T0), 2 days (T1), 4 days (T2) and 6 days (T3). It was concluded that the carbohydrate content of the sciots gave the highest positive contribution to the increase in the number of shoots followed by the number of leaves, percentage of living grafts, leaf area, leaf area ratio, root canopy ratio, shoot length, and stem diameter. The protein content cannot contribute to the growth of grafted seeds even has a tendency to inhibit growth. The fat content in the scion does not contribute to the growth of plant variables.
