Abstract

After Meijer had conducted ecological study on Mt. Gede Pangrango in 1959, the subsequent study did not monitor its d inamics. This study aimed to compare current vegetation composition and tree structure with past 50 years data based on Meijer publication. One hectare permanent plot reconstructed at submontane zone to identi fy vegetation changes during 50 years on August 2009. Vegetation analyses method was similar with 50 years ago include field tree identification, diameter at breast height (dbh), tree height, and first branch height. Result showed the species richness decreased from 233 to 166 species, diversity index (H) slightly changed from 3.39 to 3.29, and similarity index indicated the differentiation of both tree communities was 51%. Further r nore, from 63 tree species presented in 2009, 47 species was similar with 50 years ago and 16 species know n as new record. Moreover, 18 tree species recorded in 1959 had lost in 2009 i.e., Ehretia javanica, Heli( 7ia javanica, Mischocarpus frutescens, Saurauia bracteosa, Wedlandia glabrata, etc. The highest abundance oi I both studies was Villebrunea rubescens. The changes of vegetation composition and tree structure may have been caused by (1) wind disaster occurred on 1984; (2) human pressured from the nearest village; and (3 ) natural forest regeneration towards climax condition.

Abstract

Hoya has two types of leaves, succulent and non succulent. Succulent plant adapted well in extreme conditions, especially during dry period. Anatomical characters can be used to identify, classify, and determine plant relationship. The aims of this research were to identify anatomical character of succulent Hoya’s leaf and to determine their relationship. Ten examined species Hoya spp. (H. diversifolia, H. latifolia, H. dolichosparte, H. bilobata, H. lacunosa, H. verticillata, H. purpureofusca, H. kuhlii, H. oblanceolata, and H. micrantha) showed anatomical similarity in their epidermal layer, hipodermal, mesophyl, and the absence of sponge tissue at mesophyl. However, there are diversities among the species. Based on paradermal section of the leaf,  two types of stomata were only found at the abaxial side, individual stomata and both individual and stomatal cluster. Hoya diversifolia has the smallest stomatal size, while Hoya latifolia has the biggest. Hoya lacunosa has the lowest stomatal density, while Hoya bilobata has the highest. Hoya diversifolia, Hoya lacunosa, and Hoya oblanceolata have the lowest stomatal index, while Hoya bilobata has the highest. Observation on transversal section showed that Hoya purpureofusca has the lowest leaf thickness, while Hoya kuhlii has the highest. The hierarchical cluster analysis based on anatomical leaf characters showed different patterns of relationship which diversed as three groups at relationship scale 15.

Abstract

The last twenty to thirty years can be said to constitute a new renaissance botanical gardens around the world. One of the main causes is the growing concern of the world community associated with the issue of loss of biodiversity. In addition, because a greater need to be institutions that take part actively in the field of conservation of plant resources. Community botanical garden world is experiencing rapid development, not only in terms of the number of new botanical garden that is built up but also of the purpose and function. There are currently no less than 2,500 botanical gardens worldwide. To prepare for a global framework for policies, programs and priorities of the botanical garden world in the field of conservation of biodiversity, in 2000 BGCI has published the International Agenda for Botanic Gardens in Conservation, which contained the botanical gardens global mission.

Abstract

As an endoparasite, growth and development of Rafflesia occurred inside the host tissue. This  cryptic habit is one factor hindering our understanding on how the relationship of host-parasite began. The anatomical study on host-parasite tissue is the approached used in this study. Using infected root tissue of Rafflesia patma, anatomical figures depicting the early event of infection to perfect stage of a flower was derived. However, more study is still required to completely represent the whole life growth and development of Rafflesia during its early stage as endophyte.

Abstract

Botanic Garden represents an ecosystem area in which parasitic plants such as mistletoes are also incorporated. Mistletoe of Dendrophthoe pentandra (L.) Miq. (Loranthaceae) was a parasite of various plants cultivated in Botanic Gardens of Purwodadi, Bali, and Cibodas. The mistletoe attacked 143 host species which included in 48 plant families in those three Botanic Gardens. The most attacked host plants were belong to family Moraceae, especially Ficus spp., following by members of Myrtaceae, especially Syzygium spp. The ability to become parasite of various plants species assured that mistletoe of D. pentandra did not chosen certain host plants. The parasitic study of mistletoe D. pentandra is also reported in this paper.

Abstract

While quadrat shape of 10 x 10m has been commonly used in tree studies, the efficiency of this shape compared to the other shapes of size 100 m2 has not been tested. In this study, effect of various shapes of 100 m2 quadrat on measurement of Scots Pine (Pinus silvestris L.) density and basal area would be assessed. The aim was to assess the effect of quadrat shapes of 10 x 10m, 5 x 20m and 2 x 50m on the estimation of density and basal area of the pine in two woodlands in Norwich and to find the most efficient shape, statistically and with respect to sampling time. The results from all quadrat shapes similarly showed that the density and basal area of the Pines between two woodlands were significantly different. In site with lower pine density, the density and basal area measurement were not affected by variety of quadrat shapes. In site where the density of the Pine was higher, however, mean density and basal area measurement using 2x50m quadrat gave higher value than of the other two shapes. In term of efficiency, all shapes were not significantly different in statistical precision and sampling time. Shape of 5x20m, however, was more preferable as it required fewer samples before the mean of density and basal area always falls inside the 95% confidence interval of whole samples mean.

Abstract

Sejarah kehidupan menunjukkan bahwa mikroba memprakarsai munculnya kehidupan, yang kemudian diikuti oleh tanaman berhijau daun, hewan dan manusia. Meskipun manusia sebenarnya muncul setelah bentuk­bentuk kehidupan lainnya, namun pada kenyataannya, manusia telah mengalami evolusi sebagai makluk yang paling sempurna. Karena evolusi seperti itu, manusia dapat mengembangkan peradaban sehingga mampu mengubah gaya hidupnya. Dalam hal ini, teori adaptasi dan integrasi menjadi penting dalam menjaga stabilitas hubungan antara organisme satu dengan lainnya dalam sebuah ekosistem. Dengan demikian, ekosistem dengan segala relung dan isinya adalah realitas yang dinamis dan terus menerus berubah. Dalam artikel ini akan diuraikan dan dijelaskan hubungan keterkaitan antara kebudayaan di Indonesia dalam konteks konservasi sumberdaya alam dalam studi ekologi manusia (human ecology).

Abstract

Averrhoa dolichocarpa is a wild starfruit from Papua and Averrhoa leucopetala is a wild starfruit from Gorontalo. Both starfruits have unique characters of the leaves, inflorescence, flowers, and fruits. The study was conducted from February 2012 to May 2012 by observing the wild starfruits collections of Bogor Botanical Garden. Innitiation of Averrhoa dolichocarpa inflorescence takes 8-14 days, the small bud growing in 11-15 days, after one day the large bud will open and the anthesis last after 3 days. The fruit will develop and mature after 40-45 days. The flower and fruit drop rate is quite high, mostly caused by strong wind. The chlorophyll content of the leaves are very dynamic and influence by the environment and the wide of the canopy. Whereas initiation of Averrhoa leucopetala inflorescence needs 30-34 days, the small bud growing in 12-15 days, the large flower bud will open after 1 day, anthesis last after 5 days, and the fruit development needs 40-42 days to mature. Anthesis of the flowers occurred at 4:00 to 6:00 a.m. The flower and fruit drop rate is also quite high. The chlorophyll content is more static and tends to increase when the fruit developed.

Abstract

Hoya spp. (Apocynaceae: Asclepiadoideae) has differences in leaf type, there are succulent and non succulent leaf types.  Anatomical structure of Hoya spp. leaf has not been widely studied, especially for the non succulent type. The aims of this research were to explore the diversity and relationship of non succulent Hoya, based on leaf anatomical characters represented by eight species i.e. H. bandaensis, H. campanulata, H. chlorantha, H. cilliata, H. coriacea, H. coronaria, H. densifolia and H. multiflora. Hoya leaf anatomical characters were observed on the paradermal and transversal section and analyzed by using IBM SPSS version 19 sotfware for cluster analysis. According to the paradermal observation, stomata were present at lower surface (hypostomatic) for all species, and amphistomatic (both surface) for H. densifolia.  The type of stomata is cyclocytic for all species. Clustered stomata were found in H. coriacea.  Observation on transversal section showed that all of species has the normal structure i.e cuticula, upper and lower epidermis, palisade parenchyma and spongy parenchyma with the variation in the layer thickness.  The cluster analysis resulted four groups at distance scale 19. Each group has specific characters. The first group has trichomes on both sides of the leaf surface. The second group has amphistomatic stomatal. The third group has thin leaves. The fourth group has the widest stomata.
