Abstract

Callus Induction and Multiplication of Eucalyptus sp. on Various Media Callus Induction Medium (CIM) In Vitro. Callus induction in vitro can be done by planting specific part of plant such as leaf, root, stem, etc in aseptic condition by using medium that contains 2,4-D, a plat regulator for promoting callus formation. One of the objectives of callus production in vitro is to form secondary metabolites, because eucalyptus is known as a producer of essential oils. This research is an initial study for in vitro production of secondary metabolites for further research. The aim of this study was to determine the most suitable callus induction medium for callus formation and callus multiplication for Eucalyptus grown in vitro. This research was designed as a Completely Randomized Design (CRD), five treatments, repeated five times. Woody Plant Medium (WPM) was used as the basic media. Several Callus induction Medium (CIM) were used as treatments, i.e. CIM1 = 1 ppm 2,4-D; CIM2 = 1,5 ppm 2,4-D; CIM3 = 2 ppm 2,4-D; CIM4 = 1 ppm NAA+1 ppm BAP; and CIM5 = 2 ppm NAA+ 2 ppm BAP. Variables observed were the time of curly leaf formation, time of the emerging callus, colour and texture of the callus, callus’s weight, callus surface area, the weight of callus after multiplication. The result showed that CIM4 and CIM5 had the fastest emerging callus (7 days after planting), CIM1 and CIM2 formed green and crumb texture of callus, CIM1 produced the highest of callus’s weight, and CIM2 resulted in the highest of callus’s surface area. In conclusion, the most suitable CIM for callus induction was CIM1, while for callus multiplication was CM2.

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

Abstract

Tangerines (Citrus reticulata var. Tejakula) were destroyed in 1984 by CVPD, allegedly because the use of chemicals was too intensive, resulting in land degradation. Since ten years ago, these oranges have been successfully cultivated again using healthy organic cultivation, but farmers have difficulty getting organic fertilizer. This research aimed to identify and isolate the Arbuscular Mycorrhizal Fungi (AMF) on tangerines cv. Tejakula, their colonization of the roots and effect on soil fertility. Exploration was conducted by collecting root and soil samples in tangerine cv. Tejakula production centers are in the Tejakula District, Buleleng Regency. Spore isolation was conducted using wet filtration and centrifugation techniques, while root colonization by AMF was carried out using the staining method with trypan blue. The isolated spores are composited into AMF biofertilizer using volcanic sand as a carrier medium. The biofertilizer was then tested for its effect on soil fertility with three treatment levels of AMF spore doses (0, 20, and 40 spores/50 g of carrier media per plant). The results of exploration, isolation, and identification showed that three genera and six species of AMF were found. The spore density ranged from 17 to 32 per 100 g of soil (mean 24.17 ± 2.02 spores). The average root colonization by AMF was very high, ranging from 90 to 100%, and the application of AMF biofertilizer at a dose of 20 and 40 spores per plant provided soil fertility was much better than the control (0 AMF spores per plant).

Abstract

Badung River, a primary irrigation source for the subak system in South Denpasar, has been reported to contain excessive levels of heavy metals, exceeding the standard quality for irrigation water. Corn cultivated on subak systems irrigated by this irrigation source had heavy metal residues in its roots and kernels. Long-term consumption of corn containing heavy metals such as Pb, Cd, Cu, Cr, and Hg will cause toxicity to plant tissues and the human body. This study examined the content of heavy metals in soil and corn plants in subak systems in South Denpasar, which are irrigated with water from the Badung River. Remediation of the soils contaminated by heavy metals was conducted using rice straw and husk biochar (Br), coconut coir and shell biochar (Bc), vegetable and fruit waste biochar (Bw), and lignohumic biochar (Bl). The study also evaluated the effect of applying biochar on growth and yield of corn grown on soils contaminated by heavy metals. The results of this study showed that the heavy metal contents in the soil and irrigation exceeded the threshold for soil and water quality standards. The application of Bl yielded the highest biomass fresh weight and seed weight at 14% moisture content compared to other treatments. The Bl treatment also resulted in the best performance in binding and translocating heavy metals based on the bioaccumulation and translocation values ??of the biochar types. Hence, it can be concluded that the most suitable biochar for the remediation of heavy metal-contaminated paddy soils in subak systems is lignohumic biochar.
