The aim of the present study was to investigate the phenological characteristics of mangosteen and among-individual variation in flowering phenology at Bogor, Indonesia.Trees tend to flower after vegetative growth flushes and especially after dry weather. The dry period required to induce flowering in mangosteen. The fruiting season in the Bogor is from latest July to middle August. Bud stage to anthesis takes 19 days. Fruit development takes 115-140 days from anthesis. Fruits fast growth at 2-10 weeks after anthesis. After 13 weeks the growth of fruits is stop. Harvested period 44 days are from December 7 and latest in January 20. Fruits ripen over a 16-20 week period and picking is done by hand every 2-3 days. Generally, the fruits of mangosteen take 5 to 6 months to mature from fruit set. The pattern of fruit growth follows a sigmoid curve. In Bogor, mangosteen tree 25 years old, the fruit production is average of 50- 100 fruits per tree. The fruit production is depending from canopy size. The yield varies from tree to tree and from season to season.

We investigated the effect of sector (position in canopy) on translocation and distribution of 13C-photosynthates in mangosteen trees and related the findings to previous analyses of fruit quality. Our experiment was conducted on three 25-year-old mangosteen trees. Tree canopies were divided into 9 sectors based on height (bottom, middle, top) and width (inner, center, outer). One branch from each sector was labeled with 13CO2 in December 2003. Immediately after labeling, 13C concentration in l Eko Setiawan; Roedhy Poerwanto; Fumio Fukuda; Nobuo Sugiyama; Kuniyuki Saitoh; Naohiro Kubota

We investigated the effect of sector (position in canopy) on translocation and distribution of 13C-photosynthates in mangosteen trees and related the findings to previous analyses of fruit quality. Our experiment was conducted on three 25-year-old mangosteen trees. Tree canopies were divided into 9 sectors based on height (bottom, middle, top) and width (inner, center, outer). One branch from each sector was labeled with 13CO2 in December 2003. Immediately after labeling, 13C concentration in leaves from middle sectors was higher than that in leaves from other positions. 13C concentration in all leaves decreased rapidly for 24 h after 13C feeding, followed by a gradual decrease. In contrast, 13C concentration increased over time in the pericarp and aril of fruits. Translocation of 13C-photosynthates into fruit was high in Sectors 4 and 5, and in top positions (Sectors 7 to 9). At 96 h after 13C feeding, the highest distribution ratio of 13C-photosynthates was observed in stems, followed in descending order by pericarp, leaf, and aril. 13C distribution ratio in the aril was generally highest in fruits from inner and center positions. The relationship between partitioning of photosynthates and quality of mangosteen fruit, which differs among sectors, has been discussed.
