Root cutting retards scion sprouting and subsequent growth of rubber buddings

Abstract

Rubber ground nursery is one of rubber seedling propagation. However, there is still a lack of systematic studies investigating root cutting effect on rubber budding nursery. In this study, sprouting rate, scion stem diameter and plant height, and root stock diameter were observed between non-in situ and in situ buddings over five periods. The results showed that root cutting destroyed rootstock, retarded rubber scion sprouting rate and influenced subsequent growth such as plant height, scion diameter, leaf width and leaf length-width ratio.
