Abstract:
Plants being living organisms require nutrition for their growth, sustainability and development. The vital nutrient elements for plant growth are termed as essential nutrients or essential mineral elements. Essential nutrients are divided into two categories micronutrients and macronutrients. Among macronutrients Magnesium is a very important it is a key chlorophyll atom and plays a significant role in photosynthesis. Copper is a key element in the list of plant micronutrients. It is involved in various metabolic processes also functions in a variety of enzymes as a structural component. Plant growth and productivity are affected by abiotic stress. Mineral nutrients insufficiency or excess is one of these abiotic stresses which affect the plant growth. Plants have to cope with this stress for their survival. Pakistan has a most of the urban and rural community living on vegetables. Okra is a multipurpose crop due to its various uses of fresh leaves, buds, flowers pods, stems and seeds. The presentresearch was conducted to evaluate the effects of copper and magnesium salts on the morpho-anatomical characters of two hybrid Abelmoschus esculentus L. cultivars KIRAN and TARA F1. The experiment was designed in completely randomized design (CRD) with two factors (two hybrid Abelmoschus esculentus L. cultivars and three levels of Copper sulphate and Magnesium sulphate) and four replicates in each row. Morphological and anatomical parameters that were selected to study the effect of Copper and Magnesium salt shown that KIRAN Hybrid cultivar showed better growth in contrast to TARA FI under CuSO4 stress. Generally, root length, shoot length, leaf density, fresh and dry mass of KIRAN hybrid cultivar showed positive responses under copper stress as compared to TARA FI. Plants showed some anatomical adaptive strategies to cope with stress conditions like epidermal thickness, cortical thickness, endodermal cell area, metaxylem cell area, phloem thickness in root, stem and leaf is generally increased. Under MgSO4 KIRAN and TARA FI both were affected in terms their growth. Under CuSO4 + MgSO4 synergistic effect TARA F1 is better as compared to KIRAN and it showed positive response under synergistic stress in terms of its growth parameters.
