Abstract

Wild species of begonia existed in remnant forest of Cibodas Botanic Gardens, but their diversity, distribution and ecological preference were not much known. Data of condition and habitat characteristic of wild begonia are important in their cultivation. The aims of this study are to inventory the diversity of wild begonias and their distribution habitat preference in remnant forest of Cibodas Botanic Gardens. Sample were collected from four remnant forest using exploration method. Analysis of vegetation where wild Begonia existed was conducted using 1x1 m plot in around every individu of Begonia found. The principle component analysis (PCA) was carried out using R program version 2.11.0. The result showed that 50% of the mountain Begonia in West Java can be found in remnat forest area. The light intencity, soil humidity and air humidity were highly correlated to distribution of wild Begonia. The microclimate conditions in remnant forest area are appropriate with habitat of Begonia.

Abstract

Anatomical study on native Begonia in Cibodas Botanical Garden was conducted to determine their stomata types. Stomata 32 native Begonia were prepared by semi-permanent methods. Parameters observed in this study were stomata type, number, and size of stomata. The result showed that all Begonia species have anisocytic stomata and those stomata only found in abaxial leaves. Based on number of stomata, these Begonia can be classified into two groups: single stomata and single-grouped stomata. Generally, Begonia has a single stomata, however, single-grouped stomata is a determinate character of Begonia sect. Reichenheimia and sect. Diploclinium in CBG. The differences of stomata distribution in B. ozotothrix with other members of section Petermannia are needed to be clarified further.
