Abstract

The composition and density of vegetation in the mangrove areas affected soil conditions. Areas with a smooth distribution of substrat particles contain higher organic matter, and is characterized by the growth of mangrove better and more diverse. How environmental conditions affect the distribution of mangrove substrats observed in this study. The study was conducted in the area of Sungai Barong Kecil and Sungai Barong Besar which is part of the Sembilang National Park, Banyuasin District, South Sumatra. The study was conducted in May and June 2014. Location determined substrats by purposive sampling with particular consideration, and samples were taken using a modified PVC pipe at a depth of 10-30 cm, while the checkered line method with parallel lines used for observation shoreline mangrove distribution. Physical parameters such as salinity environmental chemistry, pH, and moisture. Analysis was performed on substrat particle size, substrat organic matter content, as well as the condition and type of mangrove. The results showed that the Sungai Barong Kecil area tend to have a much smoother distribution of substrat particles (clay content and higher dust). This leads to more easily grow mangroves and mangrove species were found to be more diverse (Avicennia marina, Avicennia alba, Rhizophora mucronata and Avicennia officianalis). Avicennia marina is the dominant species that indicates that the species is highly adaptable to various environmental conditions.

Abstract

The number of published reports of flower buds, anthers and on microspore culture of horticultural plants, especially in soybean is very low. The purpose of this research is to determine soybean microspores development stage based on the length of flower buds. Five local cultivars such as Argomulyo, Grobogan,Wilis, Anjasmoro and the black soybean Malika were used. Flower buds were the main material for microspore culture. Anjasmoro cultivar produces the highest number of flower bud. Anjasmoro soybean cultivar at third stage development, 3.1-3.6 mm length, was selected for microspore culture, based on plant height, length of anther, total of microspore per bud. Anjasmoro cultivar has the most late-uninucleate microspore and the total of shed of Anjasmoro microspore in the B medium with 340C for 4 day is 3820. Results revealed that Anjasmoro soybean cultivars had 354.67±59.67 μm length of anther, 2003±216 microspore per bud and the most mid and late-uninucleat microspore on 2.6-3.6 mm length flower bud. Anjasmoro soybean cultivar can be used for microspore culture.

Abstract

Tripneustes gratilla is economically important, supports small-scale, commercially important, ecological values, a prospect as a biological control agent and also considered as the commercially traded sea urchin. We review genetic aspects of T. gratilla for understanding the status to the sustainable use in the future. In GenBank, there are 267 nucleotide sequences related with T. gratilla. Most of the sequences (189 sequences) are COI gene of T. gratilla from Indo-Pacific Ocean. Study on molecular genetics mentioned that there is no genetic structure for T. gratilla distribution in Indo-Pacific Ocean including in Indonesia waters.

Abstract

In vitro culture of orchids has been developed for many purposes. Some native orchids and commercial orchid hybrids are propagated using seed germination or cut explants such as leaves, shoot tips, and roots to produce large numbers of orchid plantlets. This technique is widely used for the purpose in conservation of natural orchid species and industry of commercial orchid hybrids. However, the molecular genetic mechanism behind growth and development of these orchids during in vitro culture is still unclear, and needs to be elaborated. Recent advanced in transgenic technology in orchid is very helpful for studying the mechanism of action of key genes in various stages of orchid development during in vitro culture. In this review, an attempt to understand the role of class-1 KNOX gene and its relationship with other genes in the initiation of shoot apical meristem (SAM) for shoot development from orchid protocorm (a tubercle of developing orchid embryo) and PLBs (Protocorm Like Bodies) during in vitro culture will be discussed. It will answer the question about how the shoot formation can be controlled during growth and development of orchid cells in in vitro culture.

Abstract

Bali cattle ( Bos sondaicus ) is one of the Indonesia native cattle which is the result of wild banteng domestication. The advantages of Bali cattle, among others, are having a high fertility rate (80-82 %) and good adaptability to the new environment. It was found that there are genetic variation in several genes associated with reproductive function in Bali cattle. Some studies have reported an association between genetic variation in reproductive function of cattle. However, studies on the correlation between genetic variation reproductive genes with reproductive performance of Bali cattle are still low. This article aims to provide an overview of Bali cattle genetic variation reproductive genes and making it possible as candidate marker for selection and improving reproductive performance of Bali cattle.

Abstract

Germination and development of orchid seed of Dendrobium spectabile through in vitro method has been done with good result and yielded many seeds. Different acclimatization approach was developed with sphagnum moss medium which supplemented with the same nutrition as MUS medium. Alcoholic sugar was supplemented to increase medium moisture and antimicrobial was added to minimalized contamination which can harm orchid seeds. Planlet adaptation ability to drought stress which resulted from in vitro culture can be improved using the new medium. The medium will increase the probability of seed survival also it will normalize seed development through the acclimatization process.
