Abstract

The aim of this work was to study systems of low frequency tapping in rubber trees (Hevea spp.) using a stimulant. For this purpose, in September 1989, two experiments with common treatments were installed in producer areas. The clones IAN 717 and IAN 873 with virgin panel and eight years old were used. Six treatments and four repetitions in casual blocks were utilized during 40 months of tapping. Under the conditions of the experiment the superiority of the systems of low frequency tapping d/4 and d/7 was observed. The incidence of panel drying was higher on IAN 717, even though this clone had the best performance in terms of production of dry rubber.
