Multi-layer Budding of Oversized Rubber (Hevea brasiliences) Seedlings: Success and Growth in Different Soil Media

Abstract

The study on Multi-layer budding of oversized rubber seedling aimed at evaluating the success of multiple budding operation on single seedling of rubber tree species comprising of 4 to 7 budding layers per seedling. The experiment used randomized complete blocked design layout with 3 treatments such as 4, 5 and 7 layer budding in a single seedling replicated 4 times. Results revealed that the highest number of budding layers succeeded significantly higher as compared to 4 and 5 layers. The main survival percentage is about 79.17% for the 7 layers, 76.52% for the 5 layers and only about 55.36% for the 4 layers. Pure garden soil reported to have significant results on sprouting rate, sprout length, stalk diameter and number of leaves. This finding emphasized that budding of rejected oversized rubber seedlings grown in an abandoned nurseries can be reutilized for mass production of budded cuttings through multiple budding of 7 layers per seedlings to maximize planting materials derived from single seedlings.
