Abstract

Applications of Extracts of Fermented Immature Corn Seed and BambooSprout For Improvement of Table grape Quality of Vitis vinifera L. var.Alphonso Lavallee. The objective of the research was to determine the effect ofapplication of extracts of fermented immature corn seed and bamboo sprout for improvementof table grape quality. The research was designed as Completely Randomized Block Design,with five treatments and ten replications. The treatments were K0 (control), J50 (extract offermented immature seed of corn with concentration of 50%)), J100 (extract of fermentedimmature seed of corn with concentration of 100%), R50 (extract of fermented bamboo sproutwith concentration of 50%) and R100 (extract of fermented bamboo sprout with concentrationof 100%). The results showed that all of the treatments improved sugar content of the fruit.However, the treatment of J100 resulted in the greatest increase of berry number per-bunchand the lowest number of seed per-berry. In conclusion, for improvement of the table grapequality, the treatment of J100 was the most appropriate among other treatments used in thecurrent research.

Abstract

Vanilla (Vanilla planifolia Andrews) is a plants that has fruit with high economic value. The purpose of this study was to determine the concentration of Rootone F, types of growing media, and their combination to increase the success of one segment propagation of vanilla. This research was conducted from December 2020 to March 2021, located in Melinggih Kelod Village, Payangan, Gianyar. This study used a factorial randomized block design (RBD). Factor I: concentration of Rootone F which consists of concentrations 0 ppm (R0), 750 ppm (R1), 1.500 ppm (R2), and 2.250 ppm (R3), factor II: type of planting medium consisting of soil (T), soil + husk charcoal (TA), soil + cocopeat (TC), and soil + compost (TK) which was repeated 3 times. The concentration of Rootone F 2.250 ppm caused the highest total dry weight (4,30 g) or 49,31% higher than the 0 ppm treatment. The type of planting media soil + compost media caused the highest total dry weight (4,06 g) or 28,07% higher than the soil treatment. The combination of 2.250 ppm Rootone F with soil media + compos caused the highest total fresh weight of 85,07 g or 95,20% higher than 0 ppm Rootone F with soil media.

Abstract

Effect of H2SO4 Concentration and Soaking Time On Dormancy Breaking of Arabica Coffee (Coffea arabica L.) Kopyol Varieties This study aims to determine the effect of H2SO4 concentration and soaking time on breaking the dormancy of Kopyol Arabica coffee. The experimental design used was a factorial randomized block design with two factors. The first factor is the concentration of H2SO4, which consists of four levels, namely 0%, 10%, 20% and 30%, while the second factor is the immersion time, which consists of three levels, namely 10 minutes, 20 minutes and 30 minutes. The research was conducted at Mengani Village, Kintamani District, Bangli Regency, from August 2021 to October 2021. The results showed the interaction of H2SO4 concentration treatment and immersion time had a significant effect on the germination variable (%), maximum growth potential (%), dormancy intensity (%) and synchronous growth (%) and had no significant effect on the growth speed (%/etmal) variable. The best treatment for accelerating the breaking of dormancy is the treatment with 20% H2SO4 concentration and 20 minutes of soaking time, which breaks dormancy at 25 days after sowing and has a germination value of 91.11%, a maximum growth potential of 97.78%, a dormancy intensity of 2.22% and synchronous growth of 86.67% compared to the control, which broke dormancy at 35 days after sowing and had a germination value of 57.78%, a maximum growth potential of 64.44%, a dormancy intensity of 35.56% and synchronous growth of 53.33%.

Abstract

Effect of Number of Fruits and Type of Packaging on Physical, Chemical Properties and Shelf Life of Tomato Fruit (Lycopersicum esculentum Mill.) The demand for tomatoes increases along with the increase in economic growth and population. Efforts to maintain the quality of tomatoes are to delay ripening using various plastic packaging. This study aims to determine the effect of the right amount of fruit in the packaging and determine the suitable packaging in maintaining the physical, chemical and shelf life of tomatoes. The research was carried out from December 2020 to January 2021 at the Plant Breeding and Seed Laboratory, Faculty of Agriculture, Udayana University, Jl. PB. Sudirman, Denpasar. The experimental design used was a factorial completely randomized design (CRD) with 4 replications and 2 treatment factors so that 24 experimental units were obtained. The 2 treatment factors were as follows: packaging treatment (K) consisted of three treatments K0 = Control (without packaging), K1 = Polypropylene (PP) packaging, K2 = Polyethylene (PE) packaging and number of fruit (T) consisted of two treatments T1 = 3 pieces in a pack, T2 = 4 pieces in a pack. The results showed that the use of polypropylene packaging (K1) and the use of 3 packaged pieces (T1) were able to extend the shelf life of up to 22.75 days, compared to the polyethylene packaging type (K2). The smallest weight loss was found in the treatment of polypropylene packaging type (K1) at 4 Hsp which reached 0.05%. Treatment of the type of polypropylene packaging (K1) showed a low respiration rate at 4 Hsp which reached 22.88 mg CO2/kg/hour. The treatment of polypropylene packaging type (K1) showed the highest hardness level at 4 Hsp, namely 8.40 mm/100/gram/second. The results showed that the number of fruits per package had an effect on weight loss, respiration rate, and shelf life of tomatoes.

Abstract

The Discovery of the Content of Giberellin Acid (GA3) in Extracts of Several Plant Spesies. Several studies have found that the application of growth regulator Giberellin can induce seedless in seeded varieties and also improve fruit quality in non-seeded varieties of grapes. It is also directly responsible for cell division and is used in horticulture to promote seed germination. The high price makes it unaffordable for farmers, especially in Indonesia, so it is necessary to look for other sources of GA3 which comes from extracts of plant species in Indonesia. The aims of this study were: To detect the content of gibberellin acid (GA3) in several plant species; The research was conducted at the Agronomy & Horticulture Laboratory, Faculty of Agriculture, Udayana University. The results of the study found that fresh corn kernels (Zea mays L.), young bamboo shoots (Bambusa sp.), fern leaves (Diplazium esculentum), spinach leaves (Amaranthus spp) and shallot bulbs (Allium cepa), contained as much as 215 µg GA3 mL-1, 257 µg GA3 mL-1, 260 µg GA3 mL-1, 154 µg GA3 mL-1 and 227 µg GA3 mL-1 respectively. It can be concluded that extracts of plant materials contain GA3 and can be used as a substitute for synthetic GA3.

Abstract

Tomatoes are one of the daily necessities for people. In general, consumers favor tomatoes with few seeds. Therefore, there must be efforts made to improve the quality of tomatoes, one of which is to reduce the number of seeds, even if it is possible to make tomatoes without seeds (seedlessness). By applying Gibberellic acid (GA) during the growth phase of tomato plants, it is possible to enhance tomato quality through technology. The application of GA to certain plants can reduce the number of tomato seeds and increase their sweetness. It is necessary to discover a way to use GA-containing natural ingredients to prepare for the high cost of synthetic GA. Onions are one of the natural ingredients that contain GA. Thus, this study aimed to examine the effect of applying onion extract as a source of GA to obtain the optimum concentration of onion extract that can improve the quality of tomato fruit. The experimental design utilized Randomized-Group Design with five different treatments: no spraying, spraying with 25%, 50%, 75%, and 100% onion extract. According to the findings, the application of onion extract improved the quality of tomato fruit. This condition is reflected by a decrease in the number and weight of seeds per fruit and an increase in the fruit's vitamin C content. Therefore, it is essential to conduct this research to produce inexpensive, high-quality tomatoes to sustain the economy and increase farmers' income
