The present study reports, In vitro cultivation of the Jatropha curcas (Linn.) plant cells for evaluation of growth kinetics and total fatty acid content. Plant cells were cultivated in three major synthetic media components in triplicates. Four growth measurement parameters were selected and the data was analyzed using analysis of variance followed by Tukey's honestly significant difference (P...

Medicinal plants are rich sources of secondary metabolites. Lepidium sativum possess active compounds and secondary metabolites, including polyphenol, anthocyanin, flavonoid compounds, which are of special pharmaceutical and economic importance. Melatonin as bio-stimulator compound has a regulatory role on the amount of secondary metabolites and plant tolerance to environmental stresses. In thi...

This experiment was conducted to evaluate the effects of foliar application of different K:Ca ratios (0, 0.5, 1 and 1.5) on growth parameters, yield and fruit quality of strawberry 'Selva' in greenhouse conditions based on completely randomized design with three replicates. Based on the results, spray application showed significant effects on the photosynthetic capacity, enzymatic and non-enzym...

Drought is one of the most common stresses experienced by plants and limits plant growth throughout the world, especially in the arid and semi-arid areas. In this research, the effect of vermicompost on olive (Olea europaea L. cv. Zard) morpho-physiological traits and drought tolerance was investigated. A factorial experiment was conducted in completely randomized design with two factors, inclu...

Copper is an essential micronutrient for plant growth which is involved in many metabolic processes. However excessive amounts of copper may cause environmental pollution. With an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. The effects of heavy metals on the growth parameter...

The studies on growth regulation in black gram cv. ADT (Aduthurai) 5 exhibited significant changes in growth, physiology and yield due to chemicals and plant growth regulators. Foliar application of NAA @ 40ppm at pre-flowering stage influenced growth characteristics by showing increased plant height, more number of branches, higher leaf area index and leaf area duration. But, with regard to ph...

Dynamic root growth simulation is an important tool when analysing the mechanisms within the rhizosphere. The concentration of nutrients in the soil as well as water content is strongly dependent on the root structure. On the other hand root growth is effected by the nutrient concentration and water supply as well as other soil parameters. As a result realistic root growth models are often coup...
