Abstract

This research aims to study and determine the technique of breaking the dormancy of Jatropha seeds by giving gibberellins (GA3) and various planting positions on the growth of Jatropha seeds in the nursery. The research was carried out from June-August 2020. The experimental design used was a simple randomized block design with a combination of GA3 concentrations and seed positions with 18 treatment combinations. Each was repeated two times. The results showed that giving gibberellin concentration at different planting positions did not have an effect on germination parameters, but it did affect growth parameters. All concentrations of GA3 had no effect on seed germination, seed growth rate and vigor index, but the concentration of 500 mg L-1 at various planting positions had a better effect on plant height, number of leaves, stem diameter, fresh weight and plant dry weight Jatropha in the nursery.

Abstract

ABSTRACTOrchid plants are one of the ornamental plant commodities that have no foodreserves in their seeds and have very fine and small seed sizes making it difficult to propagate naturally. One alternative for the propagation of this plant is to carry out vegetative propagation in vitro or tissue culture. The success of plant tissue culture can not be separated from the role of media composition used. Leaf fertilizer is one of the alternative media that can be used as media material in orchid plant tissue culture because leaf fertilizers contain macro and micro nutrients that can provide nutrient intake to explants to support the growth and development of these explants. Propagation of Dian Agrihorti Dendrobium orchid plant in vitro through callus proliferation using different brands of leaf fertilizer media namely leaf fertilizer hyponex brand and growmore brand. The results of the observation showed that the most proliferative Embryogenic Callus and Proliferation Rate were produced from the treatment of adding 4 ppm growmore, namely 88.42% and 322.41%. For the best color callus parameters generated from the control treatment.

Abstract

ABSTRACTNutrients are an important factor in the cultivation of chrysanthemum cut plants.Availability of nutrients is needed during plant growth and in increasing cropproduction, therefore the addition of nutrients in the form of fertilizer is needed by cut chrysanthemum plants. The use of effective and efficient fertilizers is an indicator in the growth of chrysanthemum cut plants. The purpose of this research was to determine the optimal doses of cattle manure and biourine concentration for the growth of chrysanthemum cut plants. This research was designed with a Randomized Complete Block Design consisting of two factors. The first factor is cattle manure dose which consists of three levels, namely 2 kg per m2 (K1), 3 kg per m2 (K2), and 4 kg per m2 (K3). The second factor is the concentration of biourine which consists of 4 levels, namely 0 ml L-1 of water (B1), 250 ml L-1 of water (B2), 500 ml L-1 of water (B3), and 750 ml L-1 of water (B4). All treatments were repeated 4 times, so that a combination of 48 plots was obtained. Observation parameters included plant height, number ofleaves, stem diameter, leaf length, leaf width, chlorophyll number, flower initiation, flower diameter, flower stem diameter, and flower stalk length. The use of cattle manure at a dose of 2 kg per m2 without the addition of biourine has been able to become the optimal input for the growth of chrysanthemum cut plants.
