บทคัดย่อ (EN): A study which includes two trials was carried out to examine influence of various tapping systems on yield of two rubber clones RRIV 3 and PB 260 in the South East region of Vietnam. Two trials were established for each clone which had 8 treatments involving tapping frequencies of d3 and d4 in combination with 0, 4, 6, 8 stimulations (the non-stimulated treatments were control for each of tapping frequency). Recorded data from 2008 to 2011 showed that stimulated treatments produced higher yield (g/t/t: gram/tree/tapping) than non-stimulated treatment. Individual yields (g/t/t) of d4 treat-ments were higher than those of d3 treatments on both clones. However, the mean yield (kg/ha/year) over 4 tapping years of d4 of clone PB 260 was lower than those of d3 be-cause of lesser member of tappings. The highest production (kg/ha/year) was obtained from the treatment of d3 tapping frequency combined with 8 rounds of stimulation per year on PB 260.Conversely, there was a positive response to production of low tapping frequency (d4) on RRIV 3; as a result, yield (kg/ha/year) of d4 treatments was higher than those of d3 treatments, in which the treatment of d4 with 6 stimulations per year gave highest production. Latex physiological parameters were recorded from all treatments of these trials. The results showed that, latex physiological parameters expressed positive ac-tivity of the laticiferous system after four years under low tapping frequency and stimula-tion. Tapping panel dryness was lower than 5 percent on all treatments clones.
