Abstract

The present studies were focused on regeneration of  dendrobioum and phalaenopsis species through cloning technique as a means for ex situ conservation of  protected or valuable orchids germplasms.Experimental results indicated the growth and development of adventive shoot tip explant dendrobium was as followed : high survival percentage for explant with green color was showed by D. racianum, followed by D. laxiflorum, D. pseudoconantum, D. strebloceras,  D. lineale and D. veratrifolium. But plantlets regeneration occurred only on D. pseudoconantum and D. strebloceras . Explant regeneration from seed derived protocorm-like bodies on D. spectabile occurred 40 days after inoculation and after subcultured. High survival percentage of explant from floral stalk shoot was showed by P. amabilis. There was several plantlets survived at acclimatitation. Explant regeneration from seed derived protocorm-like bodies on P. hieroglypha occurred 40 days after inoculation and after subcultured.It was suggested that for ex situ conservation on certain species of dendrobium and phalaenopsis in the category of rare or valuable germplasms, cloning technology could be applied by using explant from adventive shoot tip, floral stalk buds and seed derived protocorm-like body explant for vegetative seed multiplication.   Keywords : Orchid, conservation, germplasms in vitro culture.

Abstract

Experiments aimed at examining the effect of aqueous extracts of three weed species on nodulation and nodule function of soybean cv. Melrose have been carried out at the Laboratory of Plant Physiology and Biotechnology, Department of Agronomy and Soil Science, University of New England, Australia. Aqueous extracts of fresh weed material (Amaranthus powellii, Cyperus rotundus and Paspalum dilatatum) at the concentration of 10% (w/v) were added to a minus-nitrogen Hoagland’s nutrient solution in which the soybean plants were grown with 14 hours day length, day and night temperatures of 28 and 20°C, respectively, light intensity of 790 mmol/m2/s, and the relative humidity of 65%. The plants were kept for three weeks prior to the measurement of activity of nitrogenase enzyme and ammonium content of the root nodules. Results demonstrate that all weed extracts reduced the nodulation and nitrogenase activities (ARA) of soybean cv. Melrose. Amaranth was most inhibitory to nitrogenase enzyme activity. However, amaranth extract was less inhibitory than nutgrass extract in total ammonium content.

Abstract

This study is aimed to test the hypothesis that the soil quality of sugarcane plantations closely linked to the particulate organic matter (POM) and earthworm’s populations. The research was conducted at five sites in Malang, East Java. The sites were selected based on differences in average annual rainfall and two types of soil management : with and without organic input. Soil samples taken from a depth of 0-20 cm were analyzed total organic C (TOC), total N, POM-C, and POM-N and earthworm’s population density and biomass. The TOC were corrected by the clay  content using pedotransfer equations so obtained TOCref. The interaction between differences in annual rainfall and two types of the treatments significantly (p

Abstract

This study was conducted to evaluate the heritability, heterosis, and correlation among firmness, total soluble solid (TSS), and color in the F1 hybrids between two day-neutral (DN) and six short-day (SD) cultivars. The firmness of DN cultivars and the sweetness of SD cultivars were considered as a criterion in choosing parent cultivars. Parents and eleven F1 progenies were grown in completely randomized block design. Heritability of TSS, color (a*: opponent channel between red/magenta and green), and firmness was 0.67, 0.55, and 0.49, respectively. Most of the DN × SD hybrids had higher firmness and TSS than the crossing of SD × SD and DN × DN, respectively. In the DN × SD progenies, all heterosis values of TSS and most of heterosis of firmness were positive and negative, respectively. The genetic advance of TSS was higher than firmness. ‘DNKW002’ was a better donor for firmness and can be used as female parent in producing DN cultivar with high TSS. Correlation between firmness and TSS was negative, hence the simultaneous selection was recommended. Principle component analysis (PCA) based on characteristics indicated three groups: group of DN parents and hybrids of DN × DN, group of SD parents and SD × SD hybrids, and group of DN × SD and SD × DN hybrids. Additional key words: firmness, total soluble solid, heritability, PCA

Abstract

Gamma irradiation to induce mutation in plant has been used intensively since several decades ago.  On maize, 275 Gy gamma irradiation have been known to increase genetic variability indicated by their morphological variation.  Identification on genetic changes by molecular technique is important to answer whether there is mutation happening on DNA level of the plants.   The objective of this research was to identify RAPD marker polymorphism on gamma irradiation mutants compared to their parents.  The initial step of the research was to select random primers could positively amplify the maize DNA.  The result showed that selection on 60 random primers yielded 15 primers that positively amplified the maize DNA.  Amplification on both mutants and their parents by those 15 selected primers indicated that only 5 primers yielding polymorphism between mutants and their parents.  Polymorphisms on mutant G1, G3 and G6 were detected on one locus, meanwhile on mutant G7, G8 and G9 were on two loci.
