Abstract
A study on defoliation was carried out on a five-year-old ciku cv Jantung in MARDI Research Station Kuala Linggi Melaka in 1997. The study was intensed on defoliation based on the hypothesis that it could trigger flushing and subsequently induced flowering in ciku. Five treatments on severity of defoliation were carried out i.e 0 Control 0.25 0.5 75 and 100. Defoliation was done only along the semi-hardwoods of the current year. Three main parameters were recorded. The number of young flushes appeared from individual shoot had shown significant difference between 0 75 and 100 to that of 25 and 50. However the number of young flushes was lower at 100 3.1 compared to Control 3.5 The highest young flushes appeared were 4.7 and 4.6 at 25 and 50 respectively. The number of flowering flushes also showed significant differences between treatments and at 25 it was 2.4. The ratio of flowering flushes flushing also showed significant differences when the highest ratio was 0.6 and the lowest was 0.4. The above study indicated that 25 defoliation was more suitable to obtain optimum flowering after labour cost was taken into considerations.
