Abstract

Rice (Oryza sativa L.) is largely cultivated in lowland area that vulnerable to flood occurrence. Root supposed to play an important role on rice tolerance to submergence stress. An experiment which conducted from January to May 2014 in Cikarawang Field Laboratory, Darmaga, Bogor, West Java aimed to study the role of root distribution on rice submergence tolerant. The experiment used Split Plot design replicated three times, with the depth of submergence as main plot and rice variety as subplot. The main plot consisted of  water depth of 5 cm (optimum), 50 cm, 60 cm and 80 cm from soil surface. The subplot consisted of four rice varieties, namely Ciherang, Inpari 30 (Ciherang Sub1), Indragiri and Margasari. Each plant was planted in a root box (30 cm x 40 cm x 5 cm) which put into container (67 cm x 47 cm x 42 cm) and placed into the pond with water depth as treatment. Submergence started when the plant was 39 DAS (Days After Seeding) for ten days. Observation conducted after the submergence stopped (49 DAS). Result showed that submergence retarded plant growth, root distribution and increase root damage for all rice varieties with the biggest effect on susceptible varieties.

Abstract

Tungro is one of the most common diseases of rice plants which caused by double infection of RTBV (Rice Tungro Bacilliform Virus) and RTSV (Rice Tungro Spherical Virus), and it gives a significant economic loss. These viruses are transmitted by green leaf hopper (Nephottetix virescens. Distant), and the interaction between host plant and the viruses were still quite difficult to be fully understood. In order to look at whether there are any differences between the healthy and tungro infected rice, this study was set to examine the character differences between the infected and the healthy plants based on isozyme banding pattern. The infected plants were collected from three districts around Surakarta (Sragen, Sukoharjo, Klaten) followed by Polyacrilamide Gel Electrophoresis (PAGE) to evaluate the isozyme banding patterns. There were peroxidase, esterase and acid phosphotase isozymes used. The results showed that the real differences of isozyme banding patterns of both healthy and tungro infected plants were discovered. In all cases, the Tungro infected rice had thicker and more band numbers compared to the healthy one. This evident suggested that Tungro infected rice could be detected early using PAGE method.

Abstract

Oviposition deterrent is chemical compounds which are used for avoiding eggs deposition. The oviposition deterrent resulted from eggs deposition is valuable information that can be manipulated for managing its population. The objective of this research was to determine the presence of oviposition deterrent resulted by female Bactrocera carambolae on mango. Extraction of oviposition deterrent was conducted by maceration method. The preference test was performed using two arms olfactometer, meanwhile the oviposition deterrent test was conducted by exposed gravid females to fruit that already smeared with extracts. The result revealed that gravid females of B. carambolae were attracted to methanol extract of 1 day after egg deposition, whereas the methanol extract of 3 and 5 days after egg deposition repelled gravid females. Oviposition deterrent test indicated that methanol extract at category 3 and 5 acted as a deterrent. The preference of gravid females of B. carambolae to different category of infested fruit extracts was probably influenced by the chemicals modification on mango after oviposition. This result suggested that the female B. carambolae do not deposit oviposition deterrent. The phenomenon of deterrence was probably as a result of chemical changes in fruit as a consequence of eggs infestation.

Abstract

Selekop (Lepisanthes amoena (Hassk.) Leenh.) plant leaves are used by the Dayak tribe of East Kalimantan as traditional cosmetics. Selekop fruit is also edible, but not well known. This study was conducted to obtain the phytochemical content and antioxidant assay in flesh, seed and pericarp extracts from the fruit of Selekop. Phytochemical analysis was conducted on ethanol extract for identification of flavonoid, alkaloid, tannin, saponin, triterpenoid and steroid. The antioxidant activity was done by DPPH assay with ascorbic acid as positive control. The flesh contained flavonoid, saponin, and tannin; the seed contained flavonoid, alkaloid, saponin, triterpenoid, and tannin; and the pericarp contained flavonoid, alkaloid, saponin, triterpenoid, and tannin. Analysis of antioxidant activity revealed the following Inhibitory Concentration (IC50 values): 122.51 ppm of flesh, 63.30 ppm of seed, 53.21 ppm of pericarp and 3.06 ppm of ascorbic acid. Based on these results, the ethanol extract of the seed and the flesh had a phytochemical content and antioxidant activity which was better than the flesh extract from Selekop fuit.

Abstract

Anthurium adreanum Lindl. cv. Nitta is an ornamental plant for cut flower industries. In vitro propagation enables a large scale production of high quality seedlings of A. adreanum quickly. The aim of this experiment was to overcome some problems in the in vitro propagation of A. adreanum, such as contamination, lack of plantlets vigor and low rate of survival in the acclimatization. In vitro propagation of A. adreanum was conducted via organogenesis from leaf explant. Explant sterilization using desogerm, antioxidant, alcohol, rifampicin, and NaOCl was the best because they reduced browning and contamination until 0 %. Organogenesis of A. adreanum was successfully initiated using MS medium added with 2,4-D and BAP at 1 mg L-1, which produced 74 shoots per explant. Shoots were best maturated in MS medium with a half strength of macro minerals added with 1 mg L-1 paclobutrazol. Survival rate increased by 7 and 14 days hardening treatment using double layer medium in the light culture room. Survival rate reached 89.3 % at 8 weeks after acclimatization.

Abstract

Rubber is an important commodity for Indonesia. Currently, a problem encountered in the propagation of rubber planting materials is the availability of ideal soils with optimum nutrition as the planting medium. Peat can be used as a growing medium but it still has weaknesses such as high level of acidity and poor in nutrient content. This study was aimed to assess the performance of rubber budded stump grown on modified potting medium and applied with different forms and rates of fertilizers. The nursery experiment consisted of 17 treatments and arranged in a randomized complete block design. After rubber nursery stage, the performance of the rubber budded stump were also monitored in the field for 10 months. Results showed that mixture of peat and soil with the application of recommended rate of solid or liquid fertilizer produced rubber budded stump with bigger stem diameter and taller plants. The potting medium stimulated early root development which led to higher nutrient uptake. These budded stump also performed better in field, showed higher leaf nutrient concentration after 6 months and produced bigger stem diameter after 10 months.

Abstract

The research objective was to evaluate the genetic diversity of Moringa oleifera, Lam (MO) and its relationship to chemical composition and in vitro gas production (IVGP). Fresh MO leaves were kept frozen in ice gels pack until laboratory analysis. Four methods applied: RAPD marker for measuring DNA concentration and purification; Kjeldhal and HPLC for analysing proximate and amino acid (AA) composition; and IVGP. MO’s four distinct morphology found: green, red, reddish green and aromatic green. RAPD result analysis was 68.8-74.7 %, it means those MO had a close genetic similarity. The morphological differences are also related to leaves chemical composition variation. The highest protein and AAs content were found in aromatic green MO. Total IVGP at 96 hours reached 95.9, 99.3, 111, 115 mL per 500 mg DM in aromatic green, green, reddish green, red MO, respectively and statistically among those was highly significant difference (P<0.01). However, DM and OM digestibility did not differ significantly and estimated ME contents were similar suggesting MO leaves had sufficient fermentable nitrogen amount required to ensure rumen microbes normal activities. Conclusively, those MO has a close genetic relationship but the aromatic green MO more beneficial due its higher content of crude protein and AAs.

Abstract

Bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious diseases in rice production. Breeding varieties specifically for their resistance to BLB disease is therefore an efficient and cost-effective strategy. However, the resistance gene for BLB can be race and non-race specific, meaning it is often overcome by the pathogen. The identification of new sources of resistance genes for Xoo is crucial in rice breeding programmes. In this study, six rice varieties were assessed using six Xoo isolates in multiple screening conditions. The GGE biplot analysis considers both genotype (G) and genotype environment (GE) interaction effects and demonstrates GE interaction. The first two principal components (PCs) accounted for 95.46% of the total GE variation in the data. Based on lesion length and stability performance, Phaladum was the most ideal genotype against all Xoo isolates in the four screening conditions. The results relayed that Phaladum indigenous rice varieties could be considered as new sources of bacterial leaf blight resistance in Thailand. In the future, the BLB resistance gene in this variety will be identified in regard to mode of inheritance and used as parental line in rice breeding programmes for resistance to BLB.

Abstract

The study aimed to determine the response of two local rice cultivars subjected to different doses of nitrogen (N) fertilizer in two paddy fields, namely Petung and Gunung Makmur in Penajam Paser Utara, East Kalimantan. The research was arranged in Nested Design with five doses of N fertilizers, two cultivars, and two locations as treatments. The doses of N fertilizers were 0, 25, 50, 75 and 100 kg N.ha-1 nested in two cultivars (Nanung and Pance Kuning) and two locations (Petung and Gunung Makmur). Each treatment was conducted in three replicates. The result showed that the Pance Kuning cultivar was superior than Nanung in Petung location in terms of the number of tillers per hill, number of productive tillers per hill, percentage of filled grain per panicle, weight of 1000 grains and potential yield. A different effect of N fertilizer was observed on the number of tillers per hill, percentage of filled grain per panicle and weight of 1000 grains. Nanung and Pance Kuning showed positive responses to the application of 75 kg N.ha-1 in Petung for the parameters of tiller number and weight of 1000 grains.
