Abstract

The research was to determine the best combination of Chrysanthemum explant and concentrations of BAP (6 - benzyl amino purine), the effect of the explant material and the effect concentrations of BAP (6 - benzyl amino purine) in vitro culture by Murashige and Skoog medium. The experimental methode was Completely Randomizes Design (CRD) which consisted of two factors. The first factor is the explant material, consisting of three standards are: P1 = node, P2 = shoots, P3 = leaf. The second factor is the concentration of BAP which consists of four levels, namely: B1 = 0.5 ppm, 1.0 ppm = B2, B3 = 1.5 ppm, B4 = 2.0 ppm. The results showed there were significant interaction on fresh weight, dry weight, number of shoots and length of shoots. The treatment combination between bud explants with BAP 0.5 ppm, showed the best results on fresh weight, number of shoots and long shoots. Use of explant shoots, can accelerate the current growth of shoots, expanding the number and length of root buds. The addition of plant growth regulators BAP 0.5 ppm in the tissue culture medium, can spur the rapid growth of shoots, root number and length of root best.Key words : in vitro, chrysanthemum, kinds of eksplant, the concentration of BAP

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

Aims of, the research were to discover the influence the legin (legume) inoculation and the manure dosage to the growth and yield of the mug beans. The research was conducted at the research station at Wedomartani, District of Sleman, the Special Region of Yogyakarta. From June up to August 2018. Field experiment was arranged on the Randomized Complete Block Design with two factors, and repeated for three times. The first factor was legin application consisted of three levels, 9 g of legin/kg seeds, 12 g of legin/kg seeds, 15 g of legin/kg seeds. The second factor was cow manure dosage application consisted of five, dosage levels 0 ton/ha, 5 tons/ha, 10 tons/ha, 15 tons/ha, 20 tons/ha. The results of the research showed that the dosage of the manure had influence to the plant’s height and the leave’s chlorophyll. The best dosage of the manure is 10 tons/ha. The dosage of legin had influence on the plant’s height, leave’s chlorophyll, number of nodules, number of pods per plant, weight of sun dried seeds per plant, weight of sun dried seeds per plot, weight of 100 seeds and weight of sun dried seeds in ton/ha. The best dosage of the legin wais 15 g legin/kg seeds. The damage level of the plant did not influenced by the dosage of manure and legin. There was no interaction between the dosage of manure and legin in all observed parameters.Keyword: Mug beans, legin, cow manure.

Abstract

Chrysanthemum cultivation in medium height plains is still facing obstacles where the agronomic properties are not as good as in the highlands. It is important to find cultivation techniques that can improve agronomic properties of chrysanthemum. The setting of additional lighting technique remains to be learned then applied at planting chrysanthemum plain medium. The research purpose is to determine the best additional length of radiation for the improvement of agronomic properties of chrysanthemum. In addition to determining the best chrysanthemum varieties to be developed in the medium height plain as Hargobinangun. The research has been conducted in Hargobinangun, Sleman in April-August 2011 in two stages. The first stage is to determine the length of the addition of irradiation to improve the agronomic properties of chrysanthemum, namely 2,3,4 and 5 hours in the evening starting at 22:00 pm. While the second stage is to look at various kinds of flower faselife varieties, namely Sakuntala, Snow white, Wastu kania, Shamrock, Puspita Nusantara, Padmabuana and Tirta ayuni. The results was showing that cultivation techniques with the addition of irradiation for 5 hours will improve agronomic traits such as chrysanthemum plant height, stem diameter, flower diameter, flower number and brightness of flower color ribbon. While the flower varieties that have good prospects to be developed in the plain medium Hargobinangun because it has a much longer period of flower freshness is Puspita Nusantara, Sakuntala and Snow White.Key words: chrysanthemum, additional lighting, faselife of flowers
