Response of Ervatamia coronaria to plant growth regulators and chemical fertilization

Abstract The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) their interactions on growth, flowering, composition Ervatamia coronaria plants. plants were fertilized monthly with NPK at rate 2, 4 6 g pot-1, in addition control Plants received treatments sprayed either Kinetin NAA 50, 100 ppm for each one, while tap water. As general, results indicated that within level fertilizer treatments, treating different concentrations NAA) resulted significant increase tested vegetative (in terms height, number branches plant-1, leaf area, leaves stem diameter, root length, fresh dry weights leaves, stems roots), flowering parameters (Viz flowers/ plant, flowers), chlorophylls content, total carbohydrates, N, P , K%, indoles phenols, gibberellins, auxins cytokinins compared control, superiority particularly highest (100 ppm) . Under same raising caused a gradual all control. Based results, it can be recommended quality coronaria, could combined pot-1 NPK.
