Abstract

Inventory study of Impatiens has been done in Sumatra. Twenty five species of Impatiens were colleted from several research sites. Based on the morphological flower and their color, 9 species among them, such as I. tujuhensis Utami & T. Shimizu, I. elephanticeps Grey-Wilson, I. sorikensis N. Utami, I. pilosivitata Grey-Wilson, I. steenisii Grey-Wilson, I. sidikalangensis Grey-Wilson, I. pseudoperezii Grey-Wilson, I. rubriflora Grey-Wilson, and I. batanggadisensis N. Utami have potential as ornamental plants. I. tujuhensis Utami et T. Shimizu is closely related to I. elephanticeps Grey-Wilson. The two taxa are characterized by lower sepal like an elephant’s trunk, but I. tujuhensis differs from I. elephanticeps in having leaf lamina pubescent above with crenulated margins, petioles with several stipulated glands, the smaller tepals densely pubescent outside, but with lateral united petals which are bent backward along the midrib, the upper portions of the lateral united petals with a brown-purple patch and the dorsal petal with dense brown-purple reticulation inside. I. sorikensis N. Utami finds its closest ally in I. pilosivitata Grey-Wilson. They differ in a number of important aspects: the shape of the lateral petals, the color of the flowers, and the shape of the leaves. I. steenisii Grey-Wilson has a broader navicular lower sepal with a short incurved spur; flowers when viewed from the front have a curious bilateral asymmetry caused by a twist in the lateral united petals. I. sidikalangensis Grey-Wilson is characterized by rather flat or shallowly cupped, white or pale pink flowers, the dorsal petal and the base of the two lateral petals stained with reddish or lilac-purple. I. pseudoperezii Grey-Wilson has large pink or purple, with long curved spurs. I. rubriflora Grey-Wilson is the only species with red flowers, with its stout inflorescence and narrow bucciniform lower sepal. I. batanggadisensis N. Utami is characterized by yellow flowers with red markings on the bases of the two lateral petals, emarginated lower petals, and glabrous leaves. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: Impatiens, Balsaminaceae, wild plant, endemic, ornamental plants

Abstract

The Genus Hoya (Apocynaceae: Asclepiadoideae) is being appreciated as exotic ornamental plant in Europe, USA and Australia, while in Indonesia as the country of origin still neglected. Indonesia was predicted have the highest Hoya species diversity (about 60 species from 150 species in the world). Among the major Islands in Indonesia, Kalimantan was predicted have the highest diversity in Hoya species. The inventory of the species has been done in the Bukit Batikap Sanctuary Forest, Muller Mountain in Central Kalimantan. Nine Hoya species of about thirties species in Kalimantan were found in Bukit Batikap, namely: H. coronaria Blume, H. cf. erythrostemma Kerr., H. latifolia G. Don., H. mitrata Kerr., H. nummularioides Const., H. pusilla Rintz, H. revoluta Wight, H. scortechinii King & Gamble, and Hoya cf. vaccinioides Hook.f. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: Hoya, diversity, Bukit Batikap, Muller Mountain, Kalimantan

Abstract

Ensiling is one solution to handle lack of forage at dry and wet season in tropical area. Napier grass (Pennisetum purpureum) is a popular crop conserved as silage, regarded with a relatively high dry matter (DM) content and adequate water soluble carbohydrates for fermentation to lactic acid. The aim of this study was to determine the effect of adding lactic acid bacteria inoculants to Napier grass at ensiling on the quality of silage. Two strain lactic acid bacteria inoculants Lactobacillus plantarum 1A-2 and 1BL-2 were added to the grass at different variation of inoculants , single or mix strain (0%, 0.1%, 0.3%, 0.5%, and 1%) with 3% of rice brand as additive, and incubated for 30 days. The 1A-2 inoculants treatment lowered the pH between 3.67 to 4.18 and increased the lactate level of the grass silage 0.3 to 0.34 mg mL-1 compared with the control and other treatments. The parameters for destruction is under 5% and DM loss was considerably lower in single inoculants 1BL-2 (0.01-3.97%) and 1A-2 (0.31-5.18%). © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: silage, fermentation, potential microorganism, lactic acid bacteria

Abstract

Biomass burning is the burning of the world’s living and dead vegetation, including grasslands, forests and agricultural lands following the harvest for land clearing and land-use change. One of the important information needed following this biomass burning is how long the burnt forest or land can be recovered, and how worst the changing occurred. Repeated burning occurred at the same place trend to clean the vegetation which leads to have the land with lower number and quality of species left. The research objective is to understand the vegetation changing following peat fires in the sapric peat type at the land preparation using belong to the local community located in the Pelalawan district, Riau province, Indonesia during the dry season in the year 2001. Before burning, logging, slashing, drying and burning the site was dominated by Uncaria glabrata at seedling stage, Ficus sundaica at sapling stage, Ficus sundaica at pole stage and Stenochlaena palustris at understorey. After logging, slashing and followed by 4 weeks drying then continued by burning with high flame temperature range from 900-1100oC, it had been found that 3-months following burning the site was dominated by Uncaria glabrata at seedling stage and Nephrolepis flaccigera at understorey while 6-months following burning the site was dominated by Parastemon uruphyllus at seedling stage and Erechites valeriantifolia at understorey stage. © 2006 Jurusan Biologi FMIPA UNS Surakarta Key words: peat fires, peat type, flame, natural regeneration, human.

Abstract

Dammar (Agathis damara) seeds categorized as an intermediate seeds since their viability tend to decrease when subjected to storage more than 2 weeks conventionally. Storage period of seeds could be prolonged when the seeds cryopreserved in liquid nitrogen since the metabolism of the cells could be minimized without loss of viability. The objective of the study was to identify suitable vitritification method for dammar storage seeds. Seed water content was decreased gradually from initial water content (28.48% as a control) using desiccators and vacuum method. Vitrification solution (PVS2) containing glycerol 30%, ethylene glycol 15% and dimethylsulfoxide (DMSO) 15% in 0.4M sucrose solution was used as a cryoprotectant of peeled or unpeeled dammar seeds during freezing process. The samples were soaked in PVS2 for 1 hour followed by exposure to liquid nitrogen in cryotube for 1 hour. The samples were then thawed in water bath at 28°C for 1 hour prior to germination in IPB-78 germinator with UDK and UKdDp germination methods. Results showed that the highest viability of cryopreserved dammar seeds (22.32% moisture content) was 100% obtained from those germinated with UKdDp method. A negative effect of cryoprotectant was occurred in both peeled and unpeeled seeds cryopreserved for 1 hour. However, it was effective for seeds cryopreserved for 4 weeks which indicate the possibility to preserve for a longer period in the future. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: dammar, Agathis damara, seeds, PVS2, crypreservation.

Abstract

The few and shallow roots caused slow growth of vanilla seedling. Mycorrhiza may increased the absorption of water and nutrients, while potassium may increased the rate of growth and strength of seedlings. This study was conducted at Sambangan Village, Buleleng, Bali in 2003 (April-Agustus 2003). The experiment was done in polybag and was arranged in Randomized Block Design with three replications. The treatments were consisted of two factors. The first factor was the rates of KCl fertilizer ( 0, 100 and 200 kg ha-1 or 0, 0,10 and 0,20 9 plant-1) and the second factor was the rates of mycorrhiza (0, 20 and 30 g plant-1). The aim of the research to study interactions between potassium and mycorrhiza and The optimum dosage the mycorrhiza on growth of vanilla (Vanilla planifolia Andrew). The resultes showed that there were interactions between potassium and mycorrhiza on fresh weight of the new shoot, root length and fresh root weight. The optimum dosage of the mycorrhiza was 20 g plant-1 with new shoot fresh weight was 25.63 g plant-1. The longest root (24.67 cm plant-1) was observed at the treatment without potasium with 20 g plant-1 mycorrhiza and this was 23% longer than control (19.93 cm plant-1). The highest fresh root weight (2.48 g plant-1 ) was observed at the dosage of 200 kg KCl ha-1 and 20 g mycorrhiza plant-1 and that was 55% heavier than control (1.60 g plant-1). The leaf number of the plant with 20 g plant-1 mycorrhiza was 6.22 and that was 18% more than control with leaf number 5.25. The total fresh weight of the seedling with 20 g plant-1 mycorrhiza was 86.74 g plant-1or 15% higher compared with control (75.18 g plant-1). The dosage of 100 kg KCl ha-1 increased the K content of the plant (2.45%K) or 35% higher than control (1.81%K). © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: Vanilla planifolia, growth, potassium, mycorrhiza.
