| Abstract: | Experiments were made on the adaptability of the fast-growing and high-yielding clone of Hevea Brasiliensis var. SCATC 7-33-97 at young stage to lower frequency tapping system with stimulants. The results showed that SCATC 7-33-97 showed strong ability in latex reproduction, high allocation rate of dry matter, and rapid flow of latex when tapped with ethrel stimulation at its early tapping period. The measures of lower tapping frequencies, shorter tapping cuts and smaller stimulant dosages were helpful to latex production and growth of the rubber trees. |
