Abstract

The experiment was conducted from June to October 2009, at Cibodas Botanical Garden. The design used in the experiment was completely randomized block with two treatments and three replicates. The first factor was four kinds of planting media (sand + husk (2:1), sand + compost (1:1), husk + compost (1:1), compost). The second factor was three kinds of fertilizers (growmore, gandasil D, hyponex) and one treatment without fertilizer (control). The results of experiment show no interaction in almost all parameters between planting media and compound fertilizers. Statistically, all parameters observed show significance (? = 0,05 and ? = 0,01) at various media. Based on the study, the best media were compost and sand + compost (1:1). These media were recommended for R. pyrifolius seedling growth.Keywords : Rubus pyrifolius, planting media, fertilizers

Abstract

Flowering and fruiting phenology were studied in five species of Rubus spp (Rubus ellipticus, Rubus fraxinifolius, Rubus lineatus, Rubus moluccanus, and Rubus pyrifolius) which collected in Cibodas Botanical Garden.  It has occurred since April 2009 to March 2010.  Flowers and flower buds was produced every month by Rubus spp., but they produced difference amount.  Furthermore, number of fruits was also shown a different in each species.  This results show that each species has a different response to environment.

Abstract

There are 69 species of Mangifera distributed worldwide, and approximately 35-40 of these species are found in tropical Asia. This widespread distribution naturally affects the functional characteristics of Mangifera species. This research aims to determine the variation in leaf functional traits of Mangifera species based on their subgenus (Mangifera and Limus) and the differences in elevation locations (Bogor Botanical Garden/lowland and Cibodas Botanical Garden/highland). The leaf's functional traits were measured through ten parameters: Fresh Weight (FW), Dry Weight (DW), Leaf Area (LA), Specific Leaf Weight (SLW), Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Chlorophyll Content (CC), Stomata Density (SD), Stomata Length (SL), and Stomata Width (SW). The observational data were analyzed using Pearson Correlation, One-Way ANOVA, and Post Hoc Test with Duncan’s Multiple Range Test (DMRT). The results showed differences in Mangifera species' leaf functional traits between subgenus and locations. It was observed that DW, LA, SLA, and CC were higher in the subgenus Mangifera than in the subgenus Limus. The results also show that the SLW, SLA, LDMC, and CC values are influenced by altitude. The differences in the functional traits of Mangifera species are driven by environmental factors that induce phenotypic changes through plasticity, reflecting their adaptation to different environments.
