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

A research was conducted to study the effect of fruit maturity on seed germination capacity of four Pyracantha species, i.e. P. koidzumi, P. angustifolia, P. crenato-serrato and P. fortunea. The fruits were collected from Cibodas Botanic Garden in two different states of fruit maturity, namely physiological maturity and harvest maturity. In general, seeds of Pyracantha spp. were starting to germinate epigeally in 5 — 14 days after sowing and the states of fruit maturity influenced seed germination capacities. In P. angustifolia and P. crenato-serrato, seed germination capacities were better if the seeds were extracted from brightly colored mature fruit (physiological maturity). Meanwhile, in P. fortune and P. koidzumi, better germination capacities were obtained in seeds extracted from dark collored drying mature fruit (harvest maturity).

Abstract

As an institute for ex situ plant conservation of high mountains, Cibodas Botanical Garden (CBG), has more than 1652 species and 8140 specimens of plant collections. An inventory of potential fruit crop in CBG which will support the conservation program had never been done before. The aim of this activity is to determine its potential collections as fruit crop. Descriptive analysis was used to analyze all the data achieved from registration unit and catalogue of (CBG). The results showed that 422 numbers of collections from 31 family, 56 genus and 114 species have high potential as a fruit crop. Moreover, Cibodas Botanical Garden has 74% collection of indigenous fruit (included 85 species) and 61% collection of underutilize fruit (included 68 species) from the total number of fruit plant collections. Most of potential plant collections are able to be developed as an edible fruit crop in Indonesia in order to enhance local food security through diversification of fruit crop.How to CiteNormasiwi, S., & Surya, M.

Abstract

Enggano Island is one of the outer islands that belongs to the Province of Bengkulu. Furthermore, there is very limited information about the diversity of bryophyte from Sumatera, especially in lowland forest, Enggano Island. The aim of this research was to provide the initial information related to the diversity of bryophytes in Enggano. The research was conducted in six forests i.e. primary, secondary and degraded forests. The results showed that 32 number of collection from 14 families, 21 genera, and 32 species were identified. Leceuneaceae was common family for liverworts while the mosses family was dominated by Hypnaceae. None of the hornworts were found in this study. Some species identified (Taxyphyllum sp., Vesicularia sp., Riccardia sp., and Thuidium sp.) have the potential benefit and biological activity. Two genera were new records to Sumatra, Gongylanthus, and Symphyogyna. Moreover, Gongylanthus sp. and Symphyogyna sp. have important records related to the habitat.How to CiteNadhifah, A., & Surya, M. I. (2016).

Abstract

Currently, Cibodas Botanical Garden (CBG) has a domestication programme of wild raspberries (Rubus sp.) from Indonesia mountain forest. One of the activities in the domestication programme is fruit breeding. In order to improve the quality of wild raspberry, two mutagens i.e. chemical (oryzalin) and physical (gamma rays) mutagens were used in the breeding programme. Moreover, seed of wild raspberries from the collection of CBG were used in the programme of mutation breeding. The results showed that each species of wild raspberries has different response on the mutagen. Percentage of seed germination were affected by mutagen of oryzalin and gamma rays. Rubus fraxinifolius and Rubus rosifolius seeds were still able to germinate after treated by 100 M of oryzalin. In the other hand, with increase in radiation above 300 Gy a reduction in percentage of germination was observed in M1 generation of Rubus lineatus and Rubus chrysophyllus.How to CiteSurya, M.

Abstract

Rubus fraxinifolius belonging to the wild raspberry group has not been developed in Indonesia. Mutation breeding using gamma-ray as mutagen which was combined with in vitro culture is one of acceleration effort to obtain superior characteristics of the fruit crops, such as larger fruit size, higher nutrition content, plant with less of spines and fruit storage ability. The R. fraxinifolius seeds were irradiated with different doses of gamma-ray ranging from 0 to 500 Gy using the 60Co (Cobalt). This research aimed to determine in vitro growth of R. fraxinifolius mutant (M1) after irradiation using gamma-ray. The results showed that the highest percentage of seed germination was obtained on the doses of 100 and 200 Gy. Furthermore, the subculture of R. fraxinifolius mutant (M1) on MS medium with the addition of BA showed the different growth on number of shoots, number of leaves, and plantlet height. Moreover, R. fraxinifolius control showed higher value of shoots, number of leaves, and plantlet height at 4 and 8 weeks after subculture compared to R. fraxinifolius mutant. MS medium with the addition of IBA showed that the number of roots of R. fraxinifolius control (5.75) was higher than that of R. fraxinifolius mutant (M1) (4.83).

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

Rubus spp. (wild raspberries) is one of genera belongs to Rosaceae, also distributed in the mountain forest of Indonesia. It has a high potency to be cultivated plant. Although, some of the potential of Rubus has already known, information of about fruit nutrients of species that distribute in the mountain forest of Indonesia are not known yet. This study was aimed to determine the fruit nutrients of five species of wild raspberries that was collected in Cibodas Botanical Garden. The results of our experiments demonstrate that the fruits nutrients contents varied among five species of wild raspberries from Indonesian mountain's forests. Rubus fraxinifolius has the highest content of sugar (5.05 g sugar per 100 g fruits) compared to Rubus rosifolius, Rubus chrysophyllus, Rubus lineatus and raspberry. During the ripening and ripe period, there were a different value of vitamin C and iron contents. The highest vitamin C of R. fraxinifolius (83.65 mg/100 gram) on the ripening fruit stage II. On the other hand, the highest vitamin C of R. rosifolius (54.30 mg/100 gram) found on the stage of ripe fruit.
