Abstract

In vitro conservation is recognized as one promising tool in conserving plant genetic resources like gladiolus when grown in the tropics. The study was conducted at the Indonesian Ornamental Crops Research Institute (IOCRI) from February 2016 to August 2018. A complete factorial experiment was set up to establish the combination of gladiolus cultivars and media compositions treatments for in vitro conservation. The results showed that the trends of plantlet survival rate and viability in every 4 months’ observation of both cultivars were similar. The highest plantlet death rate was detected during 12 – 16 months. After 24 months of storage, the differences in plantlet survival and viability were observed. Gladiolus ‘Nafa’ had higher plantlet survivals and viability than ‘Kaifa’. In respect to nutrient and sucrose concentration, full nutrient strength preserved 5% higher plantlet survival and viability than ½ MS. While media contained sucrose 90 g/l also supported plantlet survival and viability for more than 20% and 17%, respectively than lower sucrose media.

Abstract

This study used several methods to investigate the performance of aqueous extracts from some Thai weeds on antioxidants and atherosclerosis-related enzyme inhibitors. The inhibitory effect of aqueous extracts was expressed as the percentage of inhibition at a concentration of 500 μg/ml. GS-MS analysis was used to identify isolated compounds in sample extracts. The antioxidant activities were investigated using DPPH, ABTS, nitric oxide radical scavenging and oxidation of LDL. The results showed that the aqueous extract from the leaves of Bidens pilosa had greater inhibitory effects than others (71.23, 57.89 and 50.09%, respectively, except ABTS); however, B. pilosa had weaker inhibition than the positive controls. Pancreatic lipase and 15-lipoxygenase (15-LO) had inhibitory effects regarding atherosclerosis-related enzyme activities. The research found that Euphorbia hirta had stronger inhibitory activity against PL and 15-LO than other extracts (30.47 and 84.66%, respectively). Moreover, E. hirta had similar activity to quercetin against 15-LO (89.25%). Finally, isolated compounds were referred by GC-MC, the result presented more than 30 phenolic compounds and quite different characters, which might widely encouraged in antioxidants and inhibition of enzymatic activities. The results indicated that B. pilosa and E. hirta were the sources of bioactive compounds as antioxidants and anti-atherosclerosis, respectively.

Abstract

Water stress is one of the adverse factors affecting growth, development and productivity of rice. It is crucial to explore the drought tolerant rice varieties and improve their quality for sustainable production for droughtprone environments. The aim of this study was to know the ability of selected landraces (Aapjhutta, Kartika, Aanadi and Jhapamansuli) and improved varieties (Khumal-8, Khumal-10, Khumal-11 and Chainung-242) of rice to tolerate water-deficit stress in Nepal. The rice plants were grown in polyethylene pots. The pots were watered for the first two days of seedling transplantation and then watering was stopped. Survival and survival probability of seedlings were calculated. In addition, the concentration of an osmolyte (proline) was estimated after complete death of the plants in each variety. Two rice varieties, Jhapamansuli and Aapjhutta showed the highest seedling survival under water-deficit stress than the improved and other rice varieties. Results indicated that these two varieties have the ability to survive better than others under the stress by accumulating a high amount of proline as a compatible solute. Thus, these varieties can be preserved and utilized for breeding activities to develop drought tolerant and high yielding varieties.

Abstract

The plants surrounding rice field serve as a habitat and niche for entomophagous arthropods. This study aimed to identify the entomophagous arthropod species and to analyze their abundance and community in vegetables and refugia grown in the rice field. The field was surrounded by 4 species of refugia (Zinnia sp., Tagetes erecta, Cosmos caudatus, and Sesamum indicum) and 4 species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, and Luffa acutangula). The arthropod found were 67 species of predatory arthropods and 22 species of parasitoids. The predatory arthropods were mostly found in rice (51 species) followed by Zinnia sp. (15 species), and M. charantia (9 species). Parasitoid species were dominantly found in rice (19 species), Zinnia sp. (7 species), and M. charantia (6 species). The predatory arthropods mostly found were Tetragnatha javana, Tetragnatha virescens, and Paederus fuscipes, while the dominant parasitoids were Cardiochiles sp., Elasmus sp., and Snellenius sp. The parasitoid species composition in rice was more similar to those in bitter melon and zinnia. The composition of predatory arthropod species in rice was similar to those in all vegetables and refugia, except in cowpea. Zinnia sp. and M. charantia were the most chosen habitat by entomophagous arthropods.

Abstract

Water yam (Dioscorea alata L.) is an important tuber crop containing essential nutrition as an alternative food source. This study aimed to analyze the biochemical composition and nutritional value of fresh tuber of fifteen local accessions of water yam from East Java and followed by the accession selection for the recommendation of accession with the best nutritional value. Results showed that the nutritional value of proximates including moisture, carbohydrate and fiber were significantly different; except in protein, fat, and ash, with the range of moisture (65.47-82.46%), carbohydrate (17.10-29.37%), protein (1.29- 3.00%), fat (0.00-0.29%), fiber (6.70-11.62%) and ash (0.85-1.44%). The ranges of mineral contents (mg/100g) were K (224.54-483.21), Ca (15.63-61.97), Mg (16.75-43.06), Fe (1.40-13.40), Zn (0.43-2.83) and P (329.37-699.91); Na mostly not detected. The anti-nutritions contents (mg/100g) comprised tannin (63.36-167.68) and oxalic acid (12.73-44.92). Analysis through HCA showed three clusters with a range of similarity from 67% to 96%; through PCA scatter biplot clearly illustrated the variation and correlation pattern among local accessions. Six promising accessions are recommended for further breeding and development i.e. Uwi Perti/30, Uwi Bangkulit/36, Uwi Bangkulit/42, Uwi Bangkulit/43, Uwi Biru/58 and Uwi Legi/66, based on their highest carbohydrates and protein content, and the lowest fat content.

Abstract

Rhizoctonia solani is one of the harmful pathogens on mungbean, which is very challenging to be controlled. T. virens has been studied intensively and has great potency to control R. solani through mycoparasitism. Seven strains of T. virens isolated from various rhizospheres were tested for their mycoparasitic potential by observing their hyperparasitism and the production of hydrolytic enzymes. All strains showed the ability to suppress the growth of R. solani on dual culture assay as well as on culture filtrate test with the inhibition ability from 43.8 to 68.6% on the dual culture assay and from 22.2 to 71.1% on the culture filtrate assay. Inter-fungal interaction, which was observed by an electron microscope, showed hyperparasitic action of T. virens against R. solani involved the formation of the knob-like structure followed by the growth of Trichoderma hyphae inside host mycelia, coiling, lysed cell wall, and swollen of mycelial tips. Mycoparasitism of T. virens also correlated with the synthesis of hydrolytic enzymes, such as cellulase and chitinase, which influenced the overall hyperparasitic ability of T. virens against the pathogen. Based on in vitro assay, the Tv3 strain proposed as a promising strain to control R. solani due to its high growth inhibition and relatively high cellulase and chitinase productionse.

Abstract

The aim of this study was to investigate the effects of music on lettuce and alfalfa seed germination and seedling growth. Nine music treatments were used: Control (no music); Gregorian Chant; Baroque; Classical; Jazz; Rock; Nature sound; New-age; Waltz. For the duration of the study, music was played for 12 hours each day for seven days. Results showed that a significantly lower number of alfalfa seeds germinated in the rock music treatment. In contrast, the highest percentage of alfalfa seeds germinated in treatments with music was those in the classical, nature sound, and waltz treatments. In lettuce seedlings, significantly longer radicles were observed in the Gregorian chant, new-age, and waltz treatments compared to the control, whereas no such effects were evident in alfalfa seedlings. Significantly longer lettuce hypocotyls were found in Gregorian chant, jazz, nature sound, new-age, and waltz music treatments. Of these, although exposure to jazz and nature sound significantly promoted the growth of lettuce hypocotyls, the growth of alfalfa hypocotyls was inhibited under identical conditions. Lettuce seedlings grown in Gregorian chant, new-age, and waltz music produced both significantly longer radicles and hypocotyls, and are suitable to be used as an alternative method to improve seedling growth and development.

Abstract

Air temperature is an important microclimate parameter in a greenhouse as it influences root growth and controls plant growth and development. Thus, the precise monitor and model temperature under greenhouse is needed to maintain the plants in optimal conditions. This research aims to model the temperature under a greenhouse using energy balance model. The study monitored the temperature inside and outside the greenhouse in a humid tropical environment. Based on the data, heat exchange constants of greenhouse components were derived, they were: 0.0029 (solar radiation), 0.8 (air) and 0.01 (heat exchange from greenhouse component). The calibrated model enables the calculation of temperature inside a greenhouse based on its outside air temperature, wind speed, and solar radiation. Testing the model against an independent time series showed the high accuracy of the model with an R2 value of 0.99, RMSE = 0.0085 and model efficiency Ef = 0.99. Based on the results, most advantageous strategies for air temperature control inside the greenhouse include the control of air ventilation.

Abstract

Lepidopteran pests such as S. litura might cause yield losses in many crops especially during pest outbreak. The combinations of microbial and botanical insecticides were expected to increase the effectivity in controlling the respected insect pest. This research aimed to evaluate the combination of plant extracts and B. bassiana to control S. litura. The compatibility of B. bassiana with different plant extracts such as Neem, Chinaberry, Mexican Sunflower and Lantana leaves was studied in the laboratory. The compatibility was evaluated based on B. bassiana colony growth, conidia density, conidia viability, and mortality of S. litura larvae. After 12 days after application (DAA), colony growth of B. bassiana was reduced by all plant extract treatments. For the mortality of S. litura, the combined mixture of B. bassiana and 0.25% Chinaberry extract resulted the maximum mortality rate (44%). After 12 and 15 DAA, the 0.25% Chinaberry showed the highest colony growth (3.93 and 4.37 cm). The most suitable treatment was B. bassiana with 0.25% Chinaberry that had the conidial density at 1.77 x 108 conidia/ml and conidial viability of 75.63% and can enhanced the mortality of S. litura larvae.

Abstract

In the assumption of oil palm breeders, virescens oil palm type has no real economic value. Therefore, the nigrescens is more considered. However, the virescens gives a visual cue that fruits are ripe without waiting to detach. In 2010, Indonesian Oil Palm Research Institute (IOPRI) successfully planted an open-pollinated population of Cameroon oil palm. The population was characterized for virescens type frequency, as well as the bunch components, quantity and quality of crude palm oil. The virescens frequency per accession was sufficiently wide, ranging from 3.33-65.71%, and was affected by the parent type, nigrescens or virescens. Most of the virescens’s fruit form is observed to be of dura, except one sample, which was observed to be tenera. The mesocarp to fruit (MF) and industrial extraction ratio (IER) percentage are similar to the nigrescens dura, namely 37.7% and 9.5%, respectively. Its oil quality is better than nigrescens, and it has total carotene ranging from 155-1246 ppm. The oleic fatty acid is higher than 50%, and the palmitic is lower than 40%. Due to the ease of determining mature fruits, as well as the higher oil quality, virescens oil palm type is recommended to be introgressed in a breeding program.
