Abstract

The aim of this experiment was to gain the accurate concentration of cycocel growth for controlling of yellow latex mangoesteen in different age level on field water stress.  This experiment was conducted in Koto Patah village, Keliling Danau, Kerinci, Jambi and was done from June until November 2011 at the altitude of 800 - 900 meter above sea level. Factorial experiment was arranged in a randomized block design. The first factor was cycocel concentrations: 0; 1.500; 3.000; 4.500; dan 6.000 mg L-1.  The second factor was levels of age plants: <30; 30-50; and >50 years.  The data were analyzed by using analysis of variance and continued with BNT test at α=5%.  The results of experiment showed that: (1) the impact of cycocel on number and weight of perfect fruits depended on the age of manggoesteen; (2) manggoesteens which were less than 30 years old and treated with 4.500 mgL-1 cycocel could increase number and weight of perfect fruits; (3) manggoesteens which were older, 30-50 years old and above 50 years old needed less cycocel namely 1.500 mgL-1 for increasing number and weight of perfect fruis.

Abstract

The broken skin on fruit was the main problem on quality of duku. The availability of calcium on soil presumable having an effect on broken skin on fruit of duku. A field experiment to evaluated the effect of calcium in controlling the broken skin on fruit of duku was carried out in Kumpeh Ulu, Muaro Jambi, Jambi from Januari 2009 through to Februari 2010. The experiment was conducted on suboptimal land with soil acidity is 4.97 (pH H2O). Randomized Completely Block Design was used with 3 replications. The treatments consisted of 4 calcium carbonat doses i.e. 0 ton/ha, 1.0 ton/ha, 1.5 ton/ha and 2.0 ton/ha. The result showed that calsium carbonat doses decresing percentage of broken skin on fruit of duku and increasing concentration of hemicelluloce on fruit skin and fresh weight of fruit, calcium carbonat dose 2 ton/ha gave the lowest percentage of broken skin and the highest hemicelluloce concentration on fruit of duku. The highest of fresh weight of fruit at calcium carbonat dose 1 ton/ha.
