Abstract

In vitro regeneration of buds and shoots via organogenesis in two genotypes of snake plants (Sansevieria trifasciata) were established. Leaf segments (1 x 1cm) of 'Hahnii' and 'Lorentii' were cultured on Murashige and Skoog (MS) basal medium containing 2,4- dichlorophenoxyacetic acid (2,4-D) for 1 week, transferred into MS medium without plant growth regulator (MS0) for 1 week, and then cultured on MS medium containing different concentrations of N6-benzyladenine (BA) at 0, 0.1, 0.25, 0.5, 1.0 and 2.0 mg/l in three times of serial passages with 4 week intervals. The results showed that regeneration of S. trifasciata was established via indirect organogenesis. 'Lorentii' was more responsive on shoot regeneration than 'Hahni'. The most suitable BA concentration for shoot bud and shoot regeneration for both cultivars was 2 mg/l. Explants of 'Lorentii' cultured on MS medium containing 2.0 mg/l BA produced 8.6 shoot buds and 3.4 shoots per explant after 14 weeks. Shoots derived from both cultivars were successfully ex vitro rooted and acclimatized in the greenhouse with high survival rate, i.e., from 96 -100%. Keywords : organogenesis, Sansevieria trifasciata 'Hahnii' and 'Lorenti', benzyladenine

Abstract

Over the last few years, the bagworm Metisa plana Walker (Lepidoptera: Psychidae) has become an important pest of oil palm, especially in North Sumatra. Recent report suggested that the bagworm has also been found in Lampung. The report requires preliminary survey to assess M. plana status and to prepare an effective control measure for the pest. This study was conducted to determine the relative density of M. plana in North Sumatra and Lampung and to compare the effectiveness of the spraying versus fogging application to control M. plana in oil palm fields. The observation confirmed that in 2010 M. plana colonies have developed in Lampung with an average relatively similar to that in North Sumatra during 2005. The finding implies that monitoring should be taken routinely to anticipate further development of the bagworm population in Lampung. Overall results of carbosulfan treatments suggested that the fogging insecticide technique was potentially as effective as spraying technique. This finding could be beneficial for bagworm control program due to the extensive areas of oil palm and the large size of canopy. A more thorough experiment is required to explore the most economical doses and to select effective insecticides to control M. plana. Keywords : Metisa plana Walker (Lepidoptera: Psychidae), bagworm, oil palm, spraying vs. fogging application

Abstract

Al-toxicity stressed soybean will show its tolerance response by changing pod number per plant. Hence, Al-toxicity tolerance of soybean can be predicted using that character. The objective of the research was to study inheritance of pod number trait of soybean on acid soil. Development of base population was carried out by crossing the genotypes of W3898- 14-3 with MLGG 0583 and MLGG 0709 from March 2002 to January 2003. Then, from March to June 2003, 13 populations resulting from soybean base population were grown on Pulung Kencana, Tulang Bawang, Lampung, where the soil is Ultisol with Al saturity of 32.84%. The design was randomized completely block design with three replications. The space was 40 x 15 cm, one plant per hill. Results showed that based on pod number per plant, soybean tolerance was polygenically controlled, where the gene action was additive and there was no allelic and non-allelic interaction genes. Narrow sense heritability was low, while broad sense heritability was classified as high. Keywords : Al-toxicity, gene action, heritability, pod number trait, soybean

Abstract

The experiment was conducted from June to October 2009, at Cibodas Botanical Garden. The design used in the experiment was completely randomized block with two treatments and three replicates. The first factor was four kinds of planting media (sand + husk (2:1), sand + compost (1:1), husk + compost (1:1), compost). The second factor was three kinds of fertilizers (growmore, gandasil D, hyponex) and one treatment without fertilizer (control). The results of experiment show no interaction in almost all parameters between planting media and compound fertilizers. Statistically, all parameters observed show significance (? = 0,05 and ? = 0,01) at various media. Based on the study, the best media were compost and sand + compost (1:1). These media were recommended for R. pyrifolius seedling growth.Keywords : Rubus pyrifolius, planting media, fertilizers

Abstract

Amendments of soil with organic matter have been known to provide control of soilborne pathogens and to improve soil properties as well. Four sources organic matter, viz: rice straw, neem cake, chicken, and cow manure were amended one month prior to planting in soil naturally infested by Pectobacterium carotovorum subsp. carotovorum, the causal agent of hollow stalk of tobacco. Soil without added organic matter served as control and seedlings treated with streptomycin sulphate was used as a comparison. This treatment was combined with one of two sources of fertilizer N viz:, urea, and CaNO3. The field experiment was conducted in North Jember arranged in randomized blocked factorial with three replicates. The chicken manure amendment gave the best control of hollow stalk with lowest disease severity (12.03%) compared to other organic matter treatments or even control (31.31%). Chicken manure also improved plant height, yield, and the quality of flue cured tobacco. All organic matter treatments increased soil microbial populations of fungi, bacteria, and actinomycetes. This may be related to the suppression of the pathogen and the consequent reduction of disease severity. Treatment of soil with urea or CaNO3 showed no effect on disease severity or growth or quality of tobacco. Keywords : organic matter amendments, hollow stalk, Pectobacterium carotovorum subsp. carotovorum

Abstract

Corn is an important food crop in Indonesia. Plant expansion has been hampered by soilacidity problem and the protein content of many corn varieties was low. This research initiates development of soil-acid-tolerant corn with highquality- protein content. Research was done on 12 factorial treatments and 3 replications as blocks in RCBD. The first factor was corn populations: Toray-1(G1), Toray-2(G2), GS- 5(G3) and GS-10(G4). The second factor was fertilizations: P1(69 kg N+36 kg P2O5+15 kg K2O per ha)); P2(115 kg N+54 kg P2O5+30 kg K2O per ha); and P3(161 kg N+72 kg P2O5+45 kg K2O per ha). The observed variables consisted of several agronomic traits, including the protein content. Results indicated that the corn populations, in general, showed good agronomic traits. The differences were mostly between populations, not between fertilizations, and no interaction was observed. The yield potential ranged from 4.25 to 6.47 ton dry seeds per ha. The protein content of seed resulted from cross ranged from 9.84% to 11.30%, as compared to the parents of 9.11% and 12.62%. This research concludes that genetic factors play an important role as confirmed by heritability estimate (h2)=0.75.Keywords : Corn, protein, acid-soil, tolerance

Abstract

Sea level rise is a growing threat for the coastal regions of Bangladesh. It is one of the most densely populated countries of the world where 28% of the population are living in the coastal area. Bangladesh has already been affected by sea level rise through land erosion, salinity intrusion and loss in biodiversity. Saline soil has a detrimental effect upon soil physical and chemical properties. The dominant soil textural classes that occur in the saline areas of these regions are silty clay. In both of the soils pH value of the surface horizon is slightly lower than those of the subsoil and sub stratums. Cation Exchange Capacity (CEC) of all these soils varies from 12.0 to 27.6 meq/100 g soil expressing medium to high status. The organic matter content is medium to high at Asasuni and pretty low at Kalapara. In both areas, nutrient deficiencies of total nitrogen, phosphorous and potassium were quite dominant but sulphur was high. Exchangeable sodium, potassium, calcium and magnesium were in high level. The dominant water soluble cations were Na+, Ca2+, Mg2+ and K+ and anions Cl- and SO4 2-.The amount of accumulated salt was found higher at the surface and decreases with depth. Keywords : sea level rise, coastal areas, salinity, soils, flood plain

Abstract

The research was aimed to determine the type, the distribution and the incidence of banana leaf diseases in several production centers in West Sumatra, Bengkulu, North Sumatra and West Java. Direct observations on banana orchards were conducted in some districts in Simalungun, Deli Serdang and Medan (North Sumatra), Tanah Datar, Limapuluh Kota, Agam, Pariaman and Pasaman (West Sumatra), Rejang Lebong and Kepahyang (Bengkulu), Sukabumi, Purwakarta and Subang (West Java) from November to December 2006. Two banana orchards were randomly selected in each district. Plant population at the selected orchard was at least 100 plants. From each sampled orchard, if banana population consisted of similar or only one variety, 10 plants were randomly chosen according to wind direction. Meanwhile, when the banana varieties were varied, five plants were randomly selected. The result showed that Black Sigatoka and Eumusae leaf spot were found in West Sumatra, Bengkulu and North Sumatra at severity level of between 15 % to 62.31%, whilst speckle disease was mainly found in North Sumatra and in parts of West Sumatra at severity level of between 72,72% to 100% and 15 to 30%, respectively. Banana varieties that were primarily attacked by leaf diseases were Cavendish, Telor, Barangan and Emas.Keywords : bananas, black sigatoka, Eumusae, speckle, disease incidence and distribution

Abstract

Weeds in the rice fields impact the population of M. vittaticollis and several predators on rice habitat. A study was conducted during rainy season 2004-2005 and dry season 2005, which selective weeding and weed strips were applied. In selective weeding, Monochoria vaginalis, Fimbristylis miliacea, Cyperus iria, and Limnocharis flava were left, and made a weed strip at the periphery of rice plot which was consisted of those four species. Clean weeding as farmers usually do was also applied as a control treatment. Results showed that the presence of weed plant species in the earlier planting season of dry season 2005 tended to maintain the population of the predatory insects of rice pests, in particularly M. vittaticollis and Anaxipha longipennis. Population of Ophionea nigrofasciata, Paederus spp. and Micraspis inops were not different among the treatment plots during rainy season (2004-2005) and dry season (2005). The species number of predator and parasitoids seemed to increase slower in the clean weeded plot in comparing with the species number in selectively weeded or weeds strips plot at early planting season. Rice yield in the experimental plots were not significantly different. Some weeds in the rice fields may not have adverse effects on rice productivity.
