Abstract

The previously bearing and non-bearing shoots of rambutan were studied in four trees of the “Seenjonja” variety, from October, 1965 to October, 1966. The objectives were to determine the growth rate of previously non-bearing shoots; to know the number of flushes that emerge on previously bearing shoots and to determine which of the shoots studied produced inflorescence in the succeeding fruiting season.

The rate of growth of previously non-bearing shoots was rapid from October to December but decreased abruptly during the months of January to April when the amount of rainfall was limited. Out of the 200 previously non-bearing shoots originally selected from four trees, only 114 shoots or 57% produced inflorescence the following year.

Previously bearing shoots produced monthly growth flushes during the year, however, 75% of the total lateral shoots emerged in October and November. Based on the total 820 lateral shoots that emerged from previously bearing shoots in 12 months, only 181 or 22% produced inflorescences.
