Abstract

The objective of this study was to characterize salak of local varieties and their hybrids. The fruits characterized were taken from plants that were grown in October 2004. The results revealed that fruits ³ 61 g were mostly produced by hybrids, in which one of their parents was Mwr or Ph. Fruits with flesh thickness ³ 0.85 cm were mostly yielded from Sdp, Sdm, and hybrids where one of their parents was Sdp or Mwr. While fruits with edible portion ³ 65.0% were mostly yielded from Sdp, Gp, and hybrids where their female parents were Mwr, Ph, and Sdp. Fruits with small seeds (≤ 3.0 g) were observed on Gp, whilst those with big seeds (≥ 7.0 g) were on Sdm, Sdm-Sj and Sdp-Sj. Hybrids from the female of Ph and Sdp mostly gave sweet taste (TSS ≥ 20º Brix). Mwr x Sdp crossing produced non-astringent fruits, while Ph x Java (K, M, Mj), Sdp x Sjg and some Sdp x Mwr crossing as well as Mwr produced astringent fruits. The four superior characters, namely fruit ≥ 61 g, flesh thickness ³ 0.85 cm, edible portion ≥ 65%, and TSS ≥ 20º Brix were found in Mwr-Sp-8, Sdp-Sj-8, and          Ph-M-7. Fruits produced by Mwr-Sp-8 were not astringent, while those produced by Sdp-Sj-8 and Ph-M-7 were astringent. These findings suggest that the selection of parent can play an important role in improving the varieties of salak. Keywords: salak, characterization, variety, hybrid, fruit

Abstract

Acid upland soil in Indonesia has a great potential for agricultural development but the soil physical properties have been degraded. The use of manure and direct application of Gresik phosphate rock (PR) was an alternative to improve land productivity and crop yields. The objective of the study was to evaluate the effects of manure and P sources on soil physical  properties and yield of foods crop that was arranged on intensive cropping systems of upland rice + maize -/- cassava- mungbean. The experiment was carried out in Tamanbogo Station Farm, East Lampung since 2007 until 2009 using randomized complete block design with 3 replications. The treatments were (1) 10 t ha-1 manures+1 t ha-1 of PR, (2) Without manure+1 t ha-1 of PR, (3) 10 t ha-1 manures+100 kg ha-1 of SP 36, and (4) Without manure+100 kg ha-1 of SP 36. The results showed that the application of manure along with PR improved soil physical characteristics of ultisol soil and gave the highest yield of foods crops with B/C in year 3th was 3.60.

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

The distinctness assessment as one main aspect in DUS test was examined in five yardlongbean varieties that applied for PVP right. The candidates are Brawijaya 1, Brawijaya 3, Brawijaya 4, Bagong 2 and Bagong 3 which belongs to Prof. Kuswanto of Brawijaya University. The test was carried out into two planting seasons (April-June 2011 and September-December 2011). Randomized Block Design used as test design with a total population of 60 plants per variety, divided into three replicates and sample size were 21 plants or plant parts per variety. Six varieties of common knowledge KP1, KP7, Putih Super, Hijau Super, Parade, and Pangeran were chosen as comparison varieties due to their similarity. The observations were recorded on 50 DUS characteristics as listed in the test guideline document of PPU BUSS yardlongbean (PPU/PVT/19/2). Appropriate statistical analysis (cluster analysis, RBD anova and Duncan Multiple Range Test) used to empower the distincness decision. Results shows all candidates have some clear and consistent difference with their similar varieties. Thus, all candidates should pass the distinctness assessment, which confirmed by the results of statistical analysis.

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.
