Abstract

The Effect of Trichoderma spp. on Growth, Yield, and Presence of the Diseases in Peanut (Arachis hypogaea L.). The consumption of peanuts is increasing together with increasing population, increasing nutrition, food diversification and increasing the capacity of the food and animal feed industry. However, the supply of peanuts in Indonesia is continues decline due to low soil nutrients and leaf rust attacks. The efforts can be made to increase peanut productions by applying Trichoderma spp. in peanut seeds. The purpose of this study was to determine the effect of Trichoderma spp. on the growth and yield of peanut plants, identifying the effect of Trichoderma spp. on the resistance of peanut plants to disease and know the best type of Trichoderma spp. for peanut plants. The design used in this study was a randomized block design (RCBD) with the treatment of a single factor type Tricoderma spp. which consists of 7 levels, namely: control, T. koningii, T. viride, T.asperellum, T. harzianum, T. ressei and T. asperellum Bedugul Bali. The treatment was repeated 4 times. The experimental results showed that the treatment of Trichoderma spp. significant until very significant effect on most of the observation variables. The best Trichoderma spp. is T. asperellum which has a very significant effect on the total number of pods (24.25 pods), weight of pods contained/plant (62.43 g), number of seeds/plant (62.75 seeds), and lowest leaf rust intensity (34,51%).

Abstract

Influence of Mica Packaging Container Sizes on Quality and ShelfLife of Strawberry (Fragaria sp.). This study aimed to determine the effect of plastic mica container size with a total of 15 pieces of packaging and determined the best treatment for the shelf life of strawberries (Fragaria sp). This study useds a complete randomized design methodology (CRD) with one treatment, namely the type of plastic mica container size with various types of packaging types as follows: type 1 (K1), type 2 (K2), type 3 (K3) and number 15 fruit packs. The observed variables were weight loss, hardness level, shelf life, organoleptic test, respiration rate and vitamin C. The size of the packaging containers affected the physico-chemical changes in the strawberries. The treatment influenced the physico-chemical changes in the strawberries, such as the rate of respiration and vitamin C levels. The best packaging size was the smallest size (K1 ) K2 and K3 packaging container sizes. This is indicated by the lowest weight loss variable, with the value of 0.20%, the lowest value of respiration rate (20.61 CO2/ kg/hour), the highest vitamin C content (72.89 mg/100g), while in the organoleptic test, the smallest container size resulted in the highest score in fruit colour, container size has a score highest in the observation of fruit color, fruit appearance and fruit aroma. Observation of the shelf life of strawberries showed that the container size of K1 (the smallest) had an average shelf life better than K2 and K3. K1 container size produced a shelf life average of 4 days while K2 container size produce a shelf life average of 3,4 days. The shortest shelf life average was recorded in the K3 container size with a value of 3,2 days. It is concluded that the shelf life of strawberries in a packaging container at a temperature of 28-30ºC can be as long as 4 days.

Abstract

Response of Growth and Yield of Sweet Corn to Dosage of Spores of Indigenous Endomycorrhizae. Endomycorrhizae is a form of mutualism association between fungi (myces) and roots (rhiza) of higher plants. The symbiotic relationship that occurs at the roots is mutually beneficial. Plants can provide carbon organic compounds for fungal growth, whereas fungi benefit plants by increasing nutrient uptake, water, producing enzymes, antibiotics and other compounds given to host plants. The study was conducted to know the effect of dosage of spores of endomycorrhizae indigenous to growth and yield of sweet corn. The experiments were carried out in laboratories and greenhouses. The design used was a completely randomized design with one factor namely the dose of spores of endomycorrhizae consisting of three levels, i.e. D0 = without inoculation of endomycorrhizae, D1 = 75 spores of endomycorrhizae/plant, and D2 = 150 spores of endomycorrhizae/plants. The results showed that dose of spores of endomycorrhizae treatment had a significant effect on growth and yield of sweet corn. The highest fresh weight of cob was obtained at a dose of 150 spores/plant, namely 181.33 g / plant. Based on the results of this study, it is necessary to conduct research in the field using a dose of 150 spores of endomycorrhizae per plant.

Abstract

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

Abstract

Agrobacterium tumefaciens Mediated Genetic Transformation of acvB Gene in Potato (Solanum tuberosum L.). Genetic transformations are now routinely applied to plant mediated by Agrobacterium tumefaciens as the most convenient technique. This study aimed to prove the success of A. tumefaciens mediated genetic transformation in potato. A. tumefaciens LBA (pBI 121) and explant of potato shoot were used in this study. Explants were grown in vitro on Murashige and Skoog media. Transformation was implemented using smear technique by smearing A. tumefaciens to injured explant. Experimental groups consisted of two groups: control group which did not receive transformation treatment and treatment group receiving transformation treatment. Explant growth was observed through the presence of shoots, branches and the shoot height. Explants in the treatment group resulted in a higher number of shoots, branches, and shoot heights compared to control. Phenol compounds appear in explant epidermal tissue, indicating the wounds produced by A. tumefaciens infection, thus the gene predicted to be transformed. Identification by PCR is needed to prove the existence of the acvB gene in potato plants genome, using acvB specific PCR primer as the marker, such as (5?-CCCT CTAG AGAC CCGC GCCA AGGCG-3?) and (5?CGCG TCGA CCTT GTCG GAAAG -3?) with 540-bp in base pair size produced.

Abstract

Determination of Harvest Time for Quality Seed Production of Long Bean Plants (Vigna sinensis L.). Seed maturity generally occurs at the same time as fruit maturity. When the fruit reaches its physiological level, it is the best time to get seeds with high quantity and best quality. Early harvest before physiological maturity many seeds have not been completely filled so that they will produce low quality seeds because many seeds are wrinkled. Meanwhile, when harvested after physiological maturity, the seeds experience weather conditions so that many seeds experience physical and physiological quality deterioration. The research aimed to get the right harvest time in the production of quality seeds of long bean plants. This study used a randomized block design with 6 treatments at harvest pods after blooming and 4 replications. The six treatments were harvest age 14, 17, 20, 23, 26, and 29 days after the flowers bloom. The results showed that the right time to harvest pods for the production of long bean seeds was 26 days after blooming, the color of the pods has changed from green to yellow, the seeds have the highest dry weight (7,56 g), the best germination capacity (100%), and maximum vigor (88,78%).
