Abstract

The purpose of this study was to determine the effect of sengon breed stock and mycorrhiza in increasing plant height and stem diameter. This research was conducted from April 2019 to September 2019 at the Center for Research and Development of Biotechnology and Forest Plant Development in Yogyakarta. Two-factor complete randomized design with 3 replications were used in this study. First factor is seed source, namely I1 = 1-1-63-1, I2 = 1-8-77-4, I3 = Malang (Bulk), and I4 = Solomon (Bulk) and second factor is the dose of mycorrhiza, namely M0 = without mycorrhiza, M 1 = mycorrhiza 5 g/plant, M2 = mycorrhiza 10 g/plant, M3 = mycorrhiza 15 g/plant. Plant height and stem diameter were collected for data. Variance analysis (ANOVA) were used at α level 5% and continued with Duncan's Multiple Range Test (DMRT) at α level 5%. The results of the study showed interactions on combinations that were in line with mycorrhiza doses on plants height and stem diameter of 8 week after planting. Parent 1- 8-77-4 gives the best results on plants height. Seed source 1-8-77-4, 1-1-63-1, and Solomon (Bulk) gives the best stem diameter results. Mycorrhizae can increase plant growth in terms of plant height and diameter.Keyword: mycorrhizae, gall rust disease, Sengon.

Abstract

Oligo chitosan is a supplement that can increase growth, accelerate flowering, and increase productivity in several types of agricultural crops, rice and horticultural commodities. The findings of this study, encourage the authors, to further test the Oligo chitosan on the initial growth of the bulbs of Iles-iles. It is known, that Iles-iles (Amorphophallus muelleri Blume) or "Porang" is one type of tuber whose life cycle is quite long, has a slow-growing bulbil, especially in the dry season. This growth delay is caused in addition to genetic traits, also dry environmental conditions come into effect, so if entering the rainy season at a certain time span will soon show a good appearance of growth. Bulbil as a planting material, in order to grow immediately, it is necessary to strive to accelerate its growth, one of which is to use Oligo chitosan. In the cultivation of iles-iles the use of Oligo chitosan to accelerate bulbil growth has never been done. Technological innovations produced by BATAN, have the opportunity to be used in the development of crop cultivation made from tubers. This study aims to test Oligo chitosan to encourage the realization of early growth of bulbil, through the treatment of immersion time and the concentration of Oligo chitosan which is higher than previous experiments that the authors have done. The experiment was conducted in the rainy season of 2019/2020 in the experimental farm of the UPN "Veteran" Yogyakarta Wedomartani Faculty of Agriculture under a tree stand, using a Split Plot Randomized Completely Block Design (RCBD) with three replications. As the main plot is the soaking time of Oligo chitosan solution, consisting of three kinds, namely 2.5 hours (L1), 5 hours (L2), and 7.5 Hours (L3), and as a sub plot is the concentration of the solution consists of 3 stages, namely (5.0 ‰ (K1), 10 ‰ (K2), and 15 ‰ (K3) and one control (without Oligo chitosan). The data obtained were analyzed by Variance Analysis with 95% confidence level, and for the difference test the Duncan Multiple Range Test (DMRT) was used at the 5% level and the Orthogonal Contrast Test The results showed that soaking Oligo chitosan for 2.5 hours (L1) was sufficient to provide a better initial growth effect for Ilesiles bulbil, with a fairly high concentration of 15 ‰ (K3).Keywords: Oligochitosan, Iles-iles or Porang, bulbil, soaking and concentration

Abstract

Arrowroot (Maranta arundinacea L.) is a type of forest tuber plant that potentially developed as a local food crop. Arrowroot tubers can be processed as chips and starches. The difficulty of getting superior varieties and seeds in relatively large quantities and uniform can be overcome by in vitro techniques. The success of tissue culture depends on the planting media, PGR, vitamins and plant genetics. The purpose of this study was to determine the effect of giving 2.4 D and BA on the growth of arrowroot explants, as well as getting the proper concentrations of 2.4 D and BA to stimulate the growth of arrowroot tubers in vitro. The study wa conducted in a laboratory with two factors Complete Random Design Method. The first factor is the 2.4 D concentration which consists of three levels, namely: 0.5 mg / L (D1), 1 mg / L (D2) and 1.5 mg / L (D3). The second factor is the concentration of BA consisting of three levels, namely: 1 mg / L (B1), 2 mg / L (B2) and 3 mg / L (B3). Variance analysis were done at 5% level. To find out there is a real difference between treatments, Duncan Multiple Range Test (DMRT) at 5% level were conducted. The results showed that the 2.4 D treatment concentration of 1 mg / L produced a greater percentage of shoot life than other treatments. Giving 2.4 D concentrations of 1 mg / L and BA 2 mg / L stimulated quicker emergence of shoots and higher shoot lengths compared to other treatments.Keyword: 2,4 D, Benzyl adenine, Maranta arundinacea, in vitro

Abstract

The productivity of chili in terms of both quality and quantity is suppressed by the attacks of anthracnose disease caused by Colletotrichum spp. Pesticides is commonly used to control the disease. Researched was conducted to determine the antagonistic fungi and the effective dose in inhibiting the growth of the Colletotrichum spp. Antagonistic tests were performed in vivo using the direct method with three replicates. Inhibition test was arranged in a Complete Randomized Block Design (RCBD) with 7 treatments: Control, Gliocladium sp (150, 250, and 350 mL/plant) and T. harzianum (150, 250, and 350 mL/plant) with four replicates and three samples out of 20 plants per treatment. The results showed that the percentage of inhibition of T. harzianum against Colletotrichum sp. is 55% while Gliocladium sp. is 70.33% in antagonistic test. The mean of disease intensity at 11 up to 32 DAI on control is 5.61 ± 0.71% up to 20.30 ± 1.35 % respectively. It is significantly higher than Gliocladium sp. 350 mL/Plant (1.94 ± 0.45 % up to 11.15 ± 0.87 %), T. harzianum 350 mL/Plant (1.10 ± 0.58 % up to 8.68 ± 0.91 %), and T. harzianum 250 mL/Plant (2.28 ± 0.43 % up to 8.75 ± 0.79 %). No significant different is observed on mean of fresh weight of red chili fruit yield per plant. T. harzianum and Gliocladium sp. fungi are effective in controlling the attack of anthracnose disease in chili. The most efficient dose to control anthracnose disease is the application of T. Harzianum or Gliocladium sp at the dose of 250 mL/plant.Key Words: Chilli, Anthracnose, Gliocladium, Trichoderma, Colletotrichum.
