Abstract

Banana is one of the most important global agriculture commodities. Asia accounts for the production of bananas amounted to 56.4% of total banana in the world and Indonesia is one of the banana-producing countries in Asia. The demand for bananas increased need is anticipated with good cultivation techniques to meet domestic and international market demand. Plant regeneration in vitro tissue culture techniques or can be used to produce propagules true-to-type in large quantities in a relatively short period and free from disease. This research aims to study the influence of various concentrations of BA (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 mg/l) against the growth and reproduction of Cavendish banana propagules in vitro. Time appears buds, propagules length and the number of propagules per explant, and the number of primary roots of plants per explant observed after eight weeks of culture. The experiment results show that after explant grown for eight weeks on the media's treatment shows the different response. The increased concentration of BA can increase the number of shoots. The increased concentration of BA from 0.5 mg/l be 1-3 mg/l increased the number of propagules, but the number of propagules will decrease in the concentration of BA more 3.5 or 4 mg/l. In addition to BA concentration 0.5, 1 and 1.5 mg/l MS media into producing shoot buds appear faster time high, highest propagules and root amount more on banana propagules Cavendish, but the number of shoots is fewer. The best of BA concentrations to induce propagules plant bananas Cavendish is 3.0 mg/l.

Abstract

Dendrobium Gradita 31 has superior characteristics that are in demand by the market in Indonesia, so seeds with sameness quality, the same characteristics as the parent and in large quantities are needed. Tissue culture is one solution to support the availability of seeds in large quantities and have a high level of sameness quality. The process of regulating the type of ZPT and concentration in the culture media does not always produce the same regeneration pathway. This research aims to determine the regeneration pathway and to obtain the best type and concentration of cytokinin to support its regeneration pathway. This study used a completely randomized design with 3 replications. The first factor is the type of cytokinin, BA and Tdz. The second factor is the concentration of Benzyladenine and Thidiazuron, 1, 2 and 3 mg/l.. The data was analyzed using analysis of variance, and mean value was tested using tukey test 5%. The results of this study indicate that the regeneration pathway in the formation of adventitious shoots was indirect embryogenesis. The use of Tdz 3 mg/l was able to produce the highest percentage of somatic embryo formation and the highest number of somatic embryos. The fastest shoot formation time, shoot formation percentage and the highest number of shoots per clump were found BA 2 mg/l.

Abstract

Potassium is really needed by melon plants to increase the sweet taste of the fruit. The element potassium can improve the size and quality of fruit during the plant's generative period and can add a sweet taste to the fruit. Meanwhile, phosphorus functions in the process of forming plant flowers and fruit as well as increasing fruit production and ripening. The aims of the research were to study interaction between the concentration and time application of MKP fertilizer on the production and quality of melon (Cucumis melo L.) and the effect of concentration and time application of MKP fertilization on the production and quality of melon (Cucumis melo L.). This experiment used Randomized Complete Block Design, which consist 2 factors, first factor was concentration of MKP fertilizer. Second factor was time application of MKP fertilizer. Data obtained were analyzed with F test, and were continued with HSD at 5 percent when significant. Results showed that there is an interaction between the concentration of MKP fertilizer and the time of application of MKP fertilizer for melon production and quality on the parameters of fruit weight, fruit diameter and total soluble solids. Providing MKP fertilizer with a concentration of 9 g.l-1 and application time of MKP fertilizer 42 and 49 days after planting is a good combination for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total dissolved solids (13.73 °brix). Providing MKP fertilizer with a concentration of 9 g.l-1 is the best fertilizer concentration for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix). MKP fertilizer application time of 42 and 49 HST is the best time for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix).

Abstract

Orchids are the largest type of flower in the Orchidaceae family of ornamental plants, and this ornamental plant has high economic value. The problem in cultivating orchids is that orchid plants tend to grow slowly. The aim of this research was to determine the most effective concentration of Growmore leaf fertilizer (32-10-10); the best type of planting medium for orchid growth; and to find out the best combination of Growmore foliar fertilizer (32-10-10) with the type of planting medium. This research was carried out using a factorial randomized block design (RBD) with 2 factors and repeated 3 times. The first factor is concentration of Growmore leaf fertilizer (32-10-10) with concentrations of 1 g.l-1 (P1), 2 g.l-1 (P2), 3 g.l-1 (P3), and 4 g.l-1 (P4). The second factor is the type of planting medium consisting of a mixture of wood charcoal and cocopeat (M1), ferns with wood charcoal (M2), and ferns with cocopeat (M3). The results of study showed that the effectiveness of giving Growmore leaf fertilizer (32-10-10) at concentrations of 2 g.l-1, 3 g.l-1, and 4 g.l-1 it showed better results on the observed variables of plant height, increase in number of leaves, and longest leaf length compared to 1 g.l-1.  The use of fern + wood charcoal planting media showed better results in the longest root length observation variable. There is no best combination between Growmore foliar fertilizer (32-10-10) and the type of planting media for the growth of Dendrobium Airey Peach x Dendrobium discolor orchids.
