Abstract

The purpose of this study was to calculate the absolute quantity of leucocytes components of mice (Mus musculus L.) as a biological indicator of Co-60 gamma ray.  The sample of mice were grouped into 4: control; treated with Co-60 gamma ray without adaptation; treated with Co-60 gamma ray with adaptation I and treated with Co-60 gamma ray with adaptation II.  In the treatment without adaptation, mice were treated with the doses of 1.0, 1.5, 2.0, 2.5 dan 3.0 Gy.  In adaptation I, mice were adapted with radiation 0.1 Gy. Just before treated with the challenge doses and in adaptation II, the challenge doses was applied 5 hours after the mice adapted with the radiation of 0.1 Gy.  The average number of mice leucocytes in control treatment was eosinophil, rod neutrophil, segmented neutrophil, lymphocyte, and monocyte, respectively.  As a result of the radiation treatments, the number of leucocytes decreased.  The number of segmented neutrophil and lymphocytes decreased as the dose increases, while the number of eosinophil, rod neutrophil and monocytes did not significantly different among three treatments.  Therefore, the components of segmented nuetrophil and lympohocyte can be employed as a biological indicator of gamma Co-60 radiation.

Abstract

Rhododendron mucronatum G. Don. var. phoeniceum is one of ornamental plants that have high economic value and aesthetics. Problems that often experienced in propagation this plant are difficulties in producing roots on cutting and limited availability of seeds on the market. This study aims to determine the effect of plant growth regulators (Rootone-F) and length of stem cuttings on the growth of R. mucronatum G. Don. var. phoeniceum. This study employed completely randomized block design with two factors and three replications. The first factor is concentration of Rootone-F (0, 150, 300, and 450 mg/L) and the second factor is length of stem cuttings (15; 25; and 35 cm). The results showed that the concentration of Rootone-F and cuttings length has significant effect (? <0.01) to number of leaves, roots and seedling height; and cuttings length was highly significant (? <0.05) to the seedling height. Rootone-F optimum concentration for the cuttings growth of shoot R. mucronatum G. Don. var. phoeniceum is 450 mg/L which is indicated by the average value of the number of leaves as much as 8.8 leaves, the average value of the number of roots as much as 9.6 and a mean value of 0.90 cm tall seedlings when compared with controls. Cuttings with 35 cm long provide seed growth R. mucronatum G. Don. var. phoeniceum. The highest indicated by the mean number of leaves as much as 6.6 leaves, the average value of the number of roots of 8.6 and a mean value of 0.88 cm additional seedlings height compared to cuttings at 15 cm length and 25 cm.

Abstract

Arbuscular Mycorrhizal Fungi (AMF) is known as one type of biofertilizer. The carrier for this biofertilizer is usually made from inorganic material such as zeolite. Currently, it is important to find the alternative materials that can be used as biofertilizers’ carrier due to the need of lower cost and easily available, such organic matter. Rice straw and husk are some of the organic matter sources that can be used as a carrier of AMF. A glass house experiment was conducted to determine the effectiveness of different type of organic matter as a carrier of AMF’s inoculum. The experiment was arranged in factorial randomized block design with two factors, i.e. type of organic matter (zeolite as a control, straw, burnt-rice’s husk and combination of straw and rice husk 50/50 v/v) and type of different hosts of AMF’s (Jatropha sp. and Sorghum sp.). The results showed that application of burnt-rice’s husk was better carrier of AMF inoculum instead of straw or combination of straw and burnt-rice’s husk. The quality of AMF inoculum with burnt-rice’s husk as a carrier was as good as the control inoculum that used zeolite, in terms of the number of spores, the percentage of root colonization, root length colonized and root fresh weight. In summary, burnt-rice’s husk has a good potential carrier of AMF biofertilizer.

Abstract

Leaf micromorphology of 13 Bali salak cultivars was studied by using multivariate analysis (Principal component analysis). The results showed that the cultivars clustered into a main group consisted of nine cultivars (Boni, Bingin, Selem, Embad, Nangka, Penyalin, Maong, Nyuh, and Putih). However, two cultivars (Muani and Gondok) were distinctly separated from this main group and two the others Nanas and Gula were intermediate. The principal component analysis (PCA) revealed that the main group has highly correlated to the characters abaxial cell length and number of cross vein density. Muani cultivar generally had longer adaxial cells, wider guard cells and lower stomatal index than the other cultivars. These three characters strongly influenced the separation of Muani from the others. Similarly, Gondok cultivar generally had wider abaxial cells than the other cultivars that discriminated Gondok clearly from the others. Whereas, the intermediate cultivars (Gula and Nanas) were placed between the main group that consisted of nine cultivars and the two separated cultivars (Muani and Gondok). These cultivars (Gula and Nanas) had intermediate values, which influenced their separations.
