Abstract

The somatic hybridization between Mandarin Satsuma (Citrus unshiu Marc.) and Siam Madu (Citrus nobilis Lour.) is expected to produce progenies having sweet seedless fruit. The research was aimed to study flowering biology, fruit and seed development to identify parthenocarpic lines derived from somatic hybridization. The research was carried out at Pacet Experimental Station of ICABIOGRAD, Cianjur, West Java (1150 m asl), during August 2019-July 2020. The research materials were 15 citrus lines derived from somatic hybridization between Mandarin Satsuma and Siam Madu, of which 5 plants (± 2 years old) per line were prepared. Observation was carried out on flowering phenology, flower morphology, fruit development, pollen viability, and stigma receptivity. Seedless fruits from un-pollinated, selfpollinated, and cross-pollinated flowers of each line were investigated. The results showed that flower morphology of the 15 citrus lines varied in the number of petals, flower diameter, pistil length relative to the stamen, and number of stamen. The development from bud emergence to fruit ripening also varied among and within lines, ranging from 212 to 316 days. Among the lines, FS 25 showed a stronger character towards stimulative parthenocarpy. FS 84 and FS 89 were potential sources of pollen (pollenizer) to produce seedless fruits.

Abstract

Vanilla planifolia Jacks., is the only commercially cultivated orchid for its compound vanillin. This crop has had serious production limitations due to its susceptibility to Fusarium oxysporum f. sp. vanilla (Fov). Salicylic acid (SA) regulates growth and development processes and induces resistance in plants. Our study evaluated its effect on the growth and development of V. planifolia seedlings grown in vitro and in vivo. A completely randomized design was used with seedlings obtained from nodal segments (2-3 cm long) grown in MS medium with different concentrations of SA (0, 0.25, 5, and 7.5 μmol). An experimental design with four SA concentration treatments (0, 0.25, 0.5, and 1 mmol) and 12 replications was used to evaluate the effects of SA on greenhousegrown plantlets. During four weeks, the number of shoots, length, thickness, number of leaves, number and length roots, chlorophyll and carotene content for both conditions were observed. We found the 7.5 μmol and 1 mmol SA stimulated the growth and development of vanilla plantlets grown both in vivo and in vitro. SA does not affect the content of photosynthetic pigments under any growth conditions.

Abstract

The appropriate method of P fertilizer application is very important for the efficiency of P uptake and yield improvement. This research aimed to assess the growth response, seed product, and P uptake efficiency of soybean to the application of fast dissolved phosphorus fertilizer. Two consecutive potted experiments under greenhouse condition were conducted using Alfisols from Jumantono Karanganyar as planting media. The soybeans were planted and treated with six doses of P fertilizer. The treatments were designed in a completely randomized experiment with 5 replications. In the first experiment, the plants were harvested at the maximum vegetative growth for measurement of plant growth components and P uptake. In the second experiment, the plants were harvested at optimum grain maturity for seed yield and P efficiency measurements. The results showed that the application of fast dissolved-P fertilizer improved plant growth, seed yield and P uptake efficiency. Fast dissolved-P fertilizer was optimum at a dose of 100 kg/ha which was applied in a split application method at 0, 15, and 30 days after planting. However further field research is necessary to confirm the results.

Abstract

Indonesia produces a large amount of oil palm empty fruit bunch (EFB) that has potency used as media for mushroom cultivation. The research emphasized the use of EFB to grow oyster mushrooms as an alternative for delignification without chemicals. This research aimed to study the growth of oyster mushroom (Pleurotus ostreatus) at EFB based growing media treatments. The media consisted of a mixture of EFB and sawdust at the composition of 0%, 25%, 50%, 75%, and 100%. The media were also supplemented with rice bran, CaCO3, and TSP fertilizer. The data were collected on the mycelium growth and the mushroom weight. During cultivation in baglog, there was no difference in mycelium growth rate. The EFB composition of 25% showed faster growth among the other compositions, followed by the EFB composition of 50%, 75%, and 0%. The highest Biological Efficiency Ratio (BER) at 56.25% was obtained at media composition of 50%. The EFB contained in baglog also showed biodelignification process. Biodelignification has the benefit which can reduce the use of chemicals in the delignification process to convert EFB into cellulose. The highest lignin reduction (40.12%) occurred in 75% of EFB media composition, while hemicellulose (49.56%) occurred in 100% EFB media composition.

Abstract

Sclerotium rolfsii is a soil-borne pathogen causing stem and root rot disease with concomitant reduction in growth and yield of cowpea. Therefore, this study evaluated pathogenicity of S. rolfsii isolates and the management of root and stem rot disease using Trichoderma species. The isolates were obtained from cowpea rhizosphere and pathogenicity was determined using a susceptible cowpea genotype ITI0K–815-5 in an experiment arranged in a completely randomized design with four replications. In vitro and in vivo trials of Trichoderma spp. against a selected virulent isolate Sclerotium rolfsii (SR06) were conducted in the laboratory and screenhouse, respectively. All nine S. rolfsii isolates were pathogenic to the cowpea genotype, while isolate SR 06 was the most virulent with 85.56% infectivity rate. Treatments with T. virens and T. atroviride application reduced the disease incidences to 22.2% and 25.3%, respectively, compared to synthetic funguforce fungicide. Plants that were inoculated and treated with T. atroviride had significantly higher yield of 435 kg/ha than other treatments (p<0.037). Findings from this research encourages the incorporation of Trichoderma species in the integrated management of S. rolfsii pathogen and the incidence of stem and root rot disease in cowpea.

Abstract

Ferulic acid is a potent antioxidant in rice. The objective of this study was to evaluate the variations in ferulic acid and antioxidant capacity among landrace rice genotypes. The experiment is conducted under paddy field conditions in two locations. It uses a randomized complete block design with three replications, and the treatments consist of 24 landrace rice genotypes. Data are collected for yield and yield components, ferulic acid, and antioxidant capacity. Rice genotypes are significantly different for plant height, number of panicles per plant, number of seeds per panicle, 1,000 - seed weight and grain yield. Grain yields of 24 rice genotypes ranged from 1,476.9 to 4,348.1 kg/ha, and G24 is a good source for high grain yield. Variations in ferulic acid content and antioxidant capacity are found among genotypes. Ferulic acid contents range from 11.56 to 45.68 mg/100 g seed, and antioxidant capacity determined by the DPPH method ranged from 15.46 to 86.26%. G6 has the highest ferulic acid content and antioxidant capacity. These two genotypes are promising for parents in breeding programs targeting improved ferulic acid content, antioxidant capacity, and yield.

Abstract

The application of antagonist microbes to control significant diseases on crops is an essential issue in the eco-friendly and sustainable agriculture of the chrysanthemum production system. The application of antagonist consortiums is expected to synergistically suppress the pathogen more effectively than a single microbe, thus increasing the marketable flower yield. The research is carried out to evaluate the single and combined application of antagonists C. ladosporioides and PGPRs, B. subtilis, and P. flourescens to control white rust in Chrysanthemum. The results show that there is no cumulative effect from the combination of biofungicide and the PGPR on disease suppression, disease incidence, and plant growth improvement than single antagonist treatments. Compared to synthetic fungicide, biofungicide and the PGPR treatments give higher parasitism intensity, though the values were negligible among the treatments. The lowest disease intensity is recorded from synthetic fungicide treatment. The improvement of flower quality due to biofungicide, PGPR, and synthetic fungicide treatments was found only on the longer vase life than untreated plants. Observation on the compatibility of antagonists with PGPRs are still needed to increase the effectiveness in controlling white rust in Chrysanthemum.

Abstract

We examined the effect of watering and shading treatments on eugenol productivity of clove seedlings in order to provide the information of the suitable site conditions for eugenol production. After a six-month experiment growing clove seedlings under twelve treatments (3 shading treatments (0%, 60% and 80%) x 4 watering treatments (1.0, 0.75, 0.5 and 0.25 l/m2/day), the total leaf mass per tree (LM), the eugenol content per unit leaf mass (EL) and the eugenol yield per tree (EY) were measured and compared between treatments. As the results, the low watering rates reduced LM slightly; however, this effect was counteracted by the drastically increased EL under the same conditions, resulting in the highest EY in the least watered treatment (0.25 l/m2/day). Heavy shading consistently reduced LM and EL, resulting in the lowest LY under the 80% shading treatment. The relatively dryer site condition where moderate water stress is likely to occur is more suitable for planting clove trees from the aspect of the for long-term high productivity of eugenol, and that the high tree density which may cause a severe competition and a heavy mutual shading among clove trees should be avoided to maintain long term high productivity.
