The growth of three types of planting materials namely buddings and seedlings with different number of whorls and core stumps in a rubber forest plantation system was studied in three trials. In the first trial two- and four-whorled buddings of three clones (RRIM 2020 RRIM 2025 and RRIM 2027) were compared. The second trial compared growth of seedlings (PBIG GG 4 5 and 6) and three- and six-whorled buddings of RRIM 2001 and RRIM 2026. In another trial the growth of three types of planting materials namely two- and six-whorled buddings and core stumps were also compared. Generally buddings planted as advanced planting materials (withfour or six whorls) had better girth than two- or three-whorled buddings or seedlings. However advanced seedlings did not indicate the same trend. Clone RRIM 2020 had significantly better girth than RRIM 2027 in the first trial. The girth superiority of core stumps over those of two whorled buddings was maintained for 2.5 years after planting whilst the six-whorled buddings caught up with the core stumps in girth size as early as two years after planting. The significance of these findings in relation to the use of advanced planting materials to reduce the period of immaturity of rubber and for rubber forest plantation is discussed.

Abstract

The growth of three types of planting materials namely buddings and seedlings with different number of whorls and core stumps in a rubber forest plantation system was studied in three trials. In the first trial two- and four-whorled buddings of three clones (RRIM 2020 RRIM 2025 and RRIM 2027) were compared. The second trial compared growth of seedlings (PBIG GG 4 5 and 6) and three- and six-whorled buddings of RRIM 2001 and RRIM 2026. In another trial the growth of three types of planting materials namely two- and six-whorled buddings and core stumps were also compared. Generally buddings planted as advanced planting materials (withfour or six whorls) had better girth than two- or three-whorled buddings or seedlings. However advanced seedlings did not indicate the same trend. Clone RRIM 2020 had significantly better girth than RRIM 2027 in the first trial. The girth superiority of core stumps over those of two whorled buddings was maintained for 2.5 years after planting whilst the six-whorled buddings caught up with the core stumps in girth size as early as two years after planting. The significance of these findings in relation to the use of advanced planting materials to reduce the period of immaturity of rubber and for rubber forest plantation is discussed.
