Phyto-Chemical and Morphological Characters of Calendula officinalis as Affected by Micronutrients
In order to study the effect of foliar applications of micronutrients on yield, extraction oil production and chemical composition of pot marigold (Calendula officinalis), two experiments were conducted in the randomized complete block design with three replications in Shahrekord, Iran during two growing seasons 2014 and 2015. The objectives of this study were to determine the effects of foliar Fe2+, Cu2+, Zn2+, and Mn2+ applications (0, 200 and 400 ppm) on flavonoid, phenols, carotenoids, extraction percentage, dry weight of the flower and the number of flowers of pot marigold. Results showed that foliar applications of Fe2+, Cu2+, Zn2+, and Mn2+ had significant effects on fresh and dry flower yield, number of flowers, extraction oil percentage and flavonoids, phenols, carotenoids of pot marigold plants, so that the highest dry weight of flowers (11.9 g per plant), number of flowers per plant (33.5), extraction oil percentage (1) and flavonoids (31.2 mg/ 100 g F.W.), phenols (56.2 mg/ 100 g F.W.) and carotenoids (0.8 mg/ 100 g F.W.) content were obtained from the application of a combination of Fe2+, Cu2+, Zn2+, and Mn2+ at 400 ppm concentration as compared to control in the second year. It seems that in climatic and edaphic conditions of Shahrekord, the best treatments for obtaining the highest extraction percentage and morphological characters of Calendula is 400 ppm of Fe, Zn, Cu and Mn.

Marigold (Calendula officinalis) yield as affected by lamb's-quarters (Chenopodium album) competition
To study interferential effect of lamb's-quarters (Chenopodium album L.) on marigold (Calendula officinalis) yield and lamb's-quarters seed production two factorial field experiments were conducted in Tabriz, Iran, during 2010-2011. Treatments were densities of lamb's-quarters (0, 2, 4, 6 and 8 plants per meter row) and relative times of its emergence (0, 10, 20, 30 and 40 days after marigold e...متن کامل
Phenotypic and biochemical profile changes in calendula (Calendula officinalis L.) plants treated with two chemical mutagenesis.
Chemical mutagenesis is an efficient tool used in mutation-breeding programs to improve the vital characters of the floricultural crops. This study aimed to estimate the effects of different concentrations of two chemical mutagens; sodium azide (SA) and diethyl sulfate (DES). The vegetative growth and flowering characteristics in two generations (M1 and M2) of calendula plants were investigated...متن کامل
Growth and chemical composition of three pistachio cultivars as affected by soil salinity and boron fertilization
Investigation into the biological activities and chemical composition of Calendula officinalis L. growing in Tunisia
Calendula officinalis (Marigold) was characterized in respect to its chemical composition, antioxidant potential and antimicrobial activities. Five compounds were identified and quantified by LC/MS and HPLC in leaves and flowers of aqueous-methanolic extracts. Total flavonoids ranged between 44.91 and 76.44 mg QE/g dry weight in leaf and flower extracts, respectively. Rutin, quercetin-3-O-gluco...متن کامل
Nineteen carotenoids were identified in extracts of petals of orange- and yellow-flowered cultivars of calendula (Calendula officinalis L.). Ten carotenoids were unique to orange-flowered cultivars. The UV-vis absorption maxima of these ten carotenoids were at longer wavelengths than that of flavoxanthin, the main carotenoid of calendula petals, and it is clear that these carotenoids are respon...متن کامل
