FLOWERING AND FRUITING PHENOLOGY OF Rubus spp. IN CIBODAS BOTANICAL GARDEN, INDONESIA

Flowering and fruiting phenology were studied in five species of Rubus spp (Rubus ellipticus, Rubus fraxinifolius, Rubus lineatus, Rubus moluccanus, and Rubus pyrifolius) collected from Cibodas Botanical Garden from April 2009 to March 2010. Flowers and flower buds were produced every month by Rubus spp., in different amount except Rubus pyrifolius. Furthermore, each species had a different response to the environment factors. Correlation analysis shows that maximum temperature and relative humidity influenced flower and fruit production. Rubus fraxinifolius and Rubus lineatus had more economic value due to its ability to produce fruit throughout the year.
