Abstract

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

冠状病毒Ervatamia对植物生长调节剂和化学施肥的反应

摘要本试验测定了化学施肥量和叶面施用植物生长调节剂PGRs（Kinetin或萘乙酸（NAA））及其相互作用对Ervatamia coronaria植物生长、开花和化学成分的影响。除对照植物外，每月用NPK以2、4和6 g pot-1的速率对植物进行施肥。接受施肥处理的植物每月喷洒50，100ppm的Kinetin或NAA，而对照植物则喷洒自来水。总体而言，结果表明，在每一水平的肥料处理中，用不同浓度的PGRs（Kinetin或NAA）处理植物会显著增加测试的营养生长（就株高、分枝数、叶面积、叶片数、茎直径、根长度、叶片、茎和根的鲜重和干重而言），与对照相比，开花参数（花/株的Viz数、花的鲜重和干重）、叶绿素含量、总碳水化合物、N、P、K%、总吲哚和总酚、赤霉素、生长素和细胞分裂素，其中NAA的优势尤其是最高浓度（100ppm）。在相同水平的PGRs下，与对照相比，提高施肥率导致所有测试参数逐渐显著增加。基于这些结果，可以建议，为了获得最高质量的新冠Ervatamia生长和开花参数，可以用100ppm的NAA和6g pot-1 NPK对植物进行喷雾。
