this research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. effect of peanut shells composts on the growth of viola tricolor and marigold was investigated during seven months. peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. plant g...

a pot experiment was conducted to evaluate the effect of foliar spray of salicylic acid (0, 50, 100 ppm), ascorbic acid (0, 100, 200 ppm) and thiamine (0, 50, 100 ppm) on vegetative growth, flowering and photosynthetic pigments of marigold (calendula officinalis l.) plants at greenhouse of sb university of kerman, iran. results showed that application of salicylic acid and thiamine increased nu...

African marigold, being tall enough and producing large flowers suitable for preparing garlands, is the most cultivated cultivar of marigold in Nepal. Besides, pinching other improved cultural techniques, a number chemicals, hormones phyto-hormones are tested found to impart varying response marigold. This review has its importance standardizing type concentration plant growth regulators Online...

Arthropod community composition in agricultural landscapes is dependent on habitat characteristics, such as plant composition, landscape homogeneity and the presence of key resources, which are usually absent in monocultures. Manipulating agroecosystems through the insertion of in-field floral resources is a useful technique to reduce the deleterious effects of habitat simplification. Food web ...

In 2008 the efficacy of three environmentally friendly substances against apple aphid (Aphis pomi) was tested. The selected substances were cinnamic acid and two plant extracts, namely glicolic extract of comfrey (Symphytum officinale) and fluid extract of marigold (Calendula officinalis). All of the substances were tested at 0.5, 1 and 5 % concentrations. The individuals of apple aphids were c...

Bacteria have evolved numerous defences against antimicrobial agent and drug resistance in pathogen is on rise. This is due to rapid development of multi-drug resistance, limited anti-bacterial spectrum and adverse effects of available anti-microbial agents. This necessitates the search for new antimicrobials with diverse structures and novel mechanism of action. Flowers are mostly used for orn...

In the current investigation, karyotype analysis and chromosome characteristics of six populations of Calendula officinalis L.(pot marigold) from Iran are studied. Results showed that all populations were diploid (2n= 2x= 32), and had symmetrical karyotypes composing mainly of metacentric and submetacentric chromosomes. The mean chromosome length ranged from 1.05 in Karaj to 1.50 μm in...
