Abstract

An environment is strongly affected plant growth, particularly under drought condition. The obstacle for this condition can be maintained by water and nitrogen sources. The aim of this research was to determine and observe the effect of N-encapsulation on the distribution of macro nutrients in the vegetative and generative phases of rice plants (Oryza sativa L.) during rice growth. The difference of nitrogen sources will influence the nutrient absorption by roots. This research was conducted in June to September 2018 at field experiment in Batu, East Java, Indonesia. The method used a Randomized Block Design with the first factor was nitrogen sources and the second factor was field capacity as drought levels. The result showed that the proline content was 0.67 µm/g in plant treated by Urea which is higher and following by N-encapsulation at 0.52 µm/g. The proline strongly maintained grain-filling phases until field capacity 25 % at the entire nitrogen source (N-encapsulation, ZA, Urea) are 72.73 g; 69.93 g; and 66.15 g respectively. At 25 % field capacity induced length of roots and had the lowest number of tillers at 30.55 by N-encapsulation and less number of panicles was 19.33 per clump. The N accumulations were maintenance in higher concentration of leaves at 100 %field capacity compared with the other treatments.

Abstract

The use of combination of specific endophytic in tidal swamps to control stem root disease as biological control agents has not been done. It is expected that this combination is able to continuously protect plants from pathogen interference. The research was carried out in type C tidal swamp in Banjar regency of South Kalimantan, from March to November 2011, temperature 29-32oC, and pH 4.0-5.5.  The method used was Split Plot design. Biocontrol preparation for both types of endophytic was applied in seeds in 7 days after planting (DAP). Observation on high intensity and plant diseases of planting stage on tidal swamps (taradak, ampak and lacak) was conducted. The results showed that there was a reduction of disease ranging from 58.70 to 87.29%. The application of combination of two biocontrol agents (T. viride PS-2.1 + P. fluorescent PS-4.8), (Fusarium non-pathogenic PS-1.5 + P. fluorescent PS-4.8) and (T. viride PS-2.1+ FNP PS-1.5) isolate gave the best inhibition result, reduced disease intensity, and increased plant height. The result of soil analysis before and after application of endophytic showed that there was an increase in soil fertility with the element addition of N, P, K and pH. Keywords:  stem rot, endophytic combination, paddy, tidal swamp

Abstract

Durian contributes a high economic value in agribusiness of horticultural product. However, recently the attack of scale insect has devastated most of pre-production trees in Indonesia. A research with objective to know the basic information about the correct species, distribution and population abundance was done at Aripan Research Station of Indonesian Tropical Fruits Research Institute from July to August 2018. A proper identification and observation method were used to know the species identity, distribution and abundance of the insect. Biotic and abiotic factors in each clone such as nutrients content, tree morphological characteristic, light intensity, temperature and relative humidity under canopy were analysed. The result showed that Aulacaspis vitis Green was a scale insect identified associating with durian leaves. Clone Bintana and Sikapal were the most and the less preferred with the intensity of damage was 88.60 % and 38.30 %, respectively. Nutrient content especially nitrogen and water as well as canopy morphology were simultaneously the most contributed in the preference of a certain clone. The pest was preferred to clump in the East cardinal direction and no significant difference between upper and lower part of the tree including within and outside of the canopy.

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

Wolbachia that have been found to be maternally inherited in arthropods, including insects behave primarily as a reproductive parasite by inducing feminization and/or death among genetic males; causing cytoplasmic incompatibility, and activating parthenogenesis, in host insects. This research aims to detect the presence of Wolbachia in several parasitic insects and to determine the diversity of Wolbachia at the supergroup level. Insect genetic samples were collected, amplified using wsp (Wolbachia surface protein) gene and with the sequences then analyzed using species homologues drawn from the Genbank database. These activities were dedicated to detect intracellular presence of Wolbachia and assembled the phylogenetic tree of the respected bacteria. Phylogenetic analysis confirmed that Wolbachia existed in the samples belonged to the supergroup A (found in Cherapron sp.) and supergroup B (found in E. japonica). Wolbachia were detected in seven out of nine wasps i.e. Anagyrus lopezi, Ceraphron sp., Microplitis manilae, Brachymeria lasus, Scelionidae sp01, Trichogramma sp, and Exorista japonica. Single infection by Wolbachia supergroup A was detected in A. lopezi, Ceraphron sp., M. manilae, and Scelionidae sp01. Meanwhile single infection by Wolbachia supergroup B was detected only in E. japonica. Double infection by both supergroups occurred in B. lasus and Trichogramma sp. samples.

Abstract

Efforts to increase rice production through genetic improvement are often limited by the availability of natural diversity. That natural diversity can be improved through induced mutation. Selected characters can be observed since the germination phases, which may also indicate the plants survival under field conditions. Experimental design was arranged in split plot, with cultivars as main plot and mutagen doses as sub plot. The experiment consisted of 36 treatment combinations, with each treatment consisting of 10 replications. Data were recorded on percentage of first count, final count and germination rate. The data were analyzed using F-test by SAS 9.0 and mean separation was carried out by employing DMRT at 95 % (α = 5 %) of confidence level. The results showed that the best cultivar response for germination traits was Inpari 13, the best mutagen to build cultivar for germination traits was Gamma 150 Gy, and the best combination between cultivar and mutagen for germination traits was Inpago Unsoed 1 that was treated with Gamma 150 Gy. Keywords: gamma irradiation, germination, rice, sodium azide

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.
