Abstract

ABSTRACTBentul taro (Colocasia esculenta) is one of taro cultivar which has high productivity. Genetic improvement has been done by obtaining tetraploid taro. Drought tolerant cultivars can be achieved by addition of poly ethylene glycol (PEG) in vitro. The purpose of this study was to determine the effect of the treatment of PEG concentrations on in vitro growth of tetraploid shoots and to propagate shoots after PEG treatment. The explants used were diploid taro shoots, tetraploid clones 2.1.2 and 2.4.2. Shoots were planted in MS media without PEG and with PEG of 5, 10 and 15%. The growth parameters observed were petiole length, number of leaves, and number of roots every week for 6 weeks. Proline content and LC50 values were analyzed at 6 weeks after planting. Propagation of shoots after PEG treatment was carried out on MS media containing 2 mg / L BAP, 1 mg / L thiamine, and 2 mg / L adenine. Each treatment consisted of 15 shoots as replicates. The growth parameters observed were petiole length, number of leaves, and number of shoots every week for 6 weeks. The results showed that Bentul taro clones significantly affected the concentration of PEG on growth parameters. LC50 value of diploid clone was 12.16%, clone 2.1.2 was 13.54%, and clone 2.4.2 was 12.74%. The highest proline content was found at Bentul tetraploid clone 2.1.2. After PEG treatment, growth was significantly affected by PEG concentrations. All Bentul taro clones after PEG treatment produced multiple shoots.  Keywords: Taro (Colocasia esculenta), in vitro selection, diploid, tetraploid, proline, LC50, propagation

Abstract

ABSTRACTRecently, the cultivation of oyster mushroom (Pleurotus ostreatus) has increased enormously because of some reasons. Mushroom growers utilize sawdust,  byproduct of timber industry as main substrate in fruiting body production. Consequently, the availability of sawdust becomes an obstacle during mushroom cultivation. The aim of this study was to evaluate the effetivity of paddy rice straw as an alternative substrate in oyster mushroom cultivation. The paddy rice straw was inoculated with a cellulolytic microbs during composting process. They are Bacillus subtilis, Pseudomonas aeruginosa, Trichoderma harzianum and Aspergillus niger. The result showed that the fastest growing mycelia by fully colonizing 1.1 kg size baglog was obtained when the paddy rice straw was treated with B. subtilis (63.00 days), followed by the treatment with P. aeruginosa (63.67 days), A. niger (65.00 days), T.  harzianum (67.33 days), and negative control (67.33 days) respectively. On the other hand, the treatment of P. aeruginosa gaved the highest production of fruiting body (123.33g) followed by the treatment with B. subtilis (113.33g), A. niger (90.00g), control (83.33g) and T. harzianum (78.33g) per bag log over 2 period of time harvesting.  Keywords : Pleurotus ostreatus, paddy rice straw, compost

Abstract

ABSTRACTSalinity stress affects metabolic processes of plants and it can cause changes in plant morphology. Information on soybean morphological characters due to salinity stress is important for breeding programs of soybean salinity tolerant. The objective of research was to study the response of morphological characters of four soybean genotypes to salinity stress. The research was conducted in a greenhouse at Iletri (Indonesian Legumes and Tuber Crops Research Institute), Malang in 2013/2014. Four soybean genotypes consisted of Wilis and Tanggamus varieties ( salinity sensitive), IAC100/Bur//Mal-10-KP-21-50 (G1) and Argopuro // IAC100 (G2) that are tolerant to salinity. The genotypes were tested at five levels of soil salinity i.e. 1.5 dS/m, 6.6 dS/m, 10.9 dS/m, 13.4 dS/m and 15.6 dS/m. Treatments arranged in randomized complete block design, replicated three times. The results showed that increasing salinity decreased plant height, leaf chlorophyll content index (CCI) and seed size, and increased scorch score in all genotypes. Increasing salinity reduced CCI by 45% on sensitive genotypes, but no symptoms on tolerant genotypes. Density and lenght of trichomes of G1 and G2 genotypes were higher than Wilis and Tanggamus. Stomata of G1 and G2 genotypes opened 93% wider than Wilis and Tanggamus. At salinity level 15.6 dS/m, seed size of G1 was 9.4 g/100 seeds and G2 was 10.2 g/100 seeds, while Wilis and Tanggamus could not perform seeds. G1 and G2 genotypes are potential to be developed as new soybean variety tolerant to salinity up to 15.6 dS/m.Keywords: salinity, morphological character, Glycine max L.Merr

Abstract

Spodoptera exigua nucleopolyhedrovirus (SeNPV) is an entomophathogenic virus of S. exigua larvae commonly usedas bioinsecticide. This research was aimed to 1) study the symptoms of SeNPV infection on the S. exigua larvae inthe laboratory, 2) examine the virulence of SeNPV on the 3rd instar of S. exigua larvae and (3) find out the optimalconcentration of polyhedra and harvesting time. The infection of SeNPV on the S. exigua larvae was inhibitedmolting process and disturbing larval growth. The color of infected larvae gradually changed become more dark,and at the end of infection, larvae died with fragile and broken integument. Infected larvae showed reduction infeeding activities. The LC50 of SeNPV on 3rd instar larvae in the laboratory was estimated 6.65 x 105 POBs/ml.The polyhedra concentration used for virus propagation was 5.88 x 106 POBs/ml. The optimal harvesting time was5 days after inoculation, where most of the infected larvae had died but the body still intact.Keywords: Pathology, symptom, virulence, Spodoptera exigua, SeNPV
