Abstract

A series experiment was conducted to study the effect of strangulation on flowering and fruiting of ‘Nambangan’ pummelo trees. Three experiments were conducted at Cikabayan Research Station IPB from October 2000 to July 2007. In the experiment 1 strangulation was applied using wire size 1.6 and 2.0 mm with a period of strangulation 1, 2, and 3 months. In the experiment 2, the pummelo trees were strangulated using 2.0 and 3.0 mm wire size for three months period. In experiment 3, the pummelo trees were subjected to 3, 5, and 7 months period of strangulation. The result of the experiment 1 showed that strangulation significantly improved flowering. About 89-100% of the treated trees produced flower, meanwhile all control trees were not flowered. The flower and fruit numbers and carbohydrate content in leaves produced were significantly higher on the trees treated with wire size of 2 .0 mm in 3 months duration. From experiment 2, the result showed that strangulation application using 3.0 mm wire size produced slightly more flower as compared with 2.0 mm. The result of experiment 3 showed that different duration of strangulation produced no significant different in the flower number and carbohydrate content in leaves. Meanwhile, it was noted that application of seven month strangulation duration caused severe damage on the phloem tissues. It is recommended that to improve flowering and fruiting of pummelo trees without significant damages, the strangulation should be applied using 2.0 – 3.0 mm of wire for not more than 3 months duration.
