Artichoke (Cynara scolymus) is peculiar among the vegetables due to its medicinal properties. Previous studies have been shown that Ultraviolet (UV) radiation stimulates the production of some secondary metabolites in the plants. In the present study, the effects of UV-A (360 nm) radiation on total phenolic content, total flavonoid content, antioxidant capacity, cynarin content and some morphop...

in order to investigate the effects of corm tunic, corm weight and drought stress on saffron (crocus sativus l.), an experiment was conducted at the greenhouse of ferdowsi university of mashhad, iran. treatment were combination of four corm weights range (2-4, 4-6, 6-8 and 8-10 g), two levels of water availability (100% field capacity and drought) and two levels of corm tunic (natural corm with...

Triacontanol (TRIA), a plant growth regulator that is effective in reducing the effects of abiotic stresses. In order to investigation the effects of interaction between arsenic and TRIA treatment on some physiological indicators of coriander the present study carried out  based on a factorial experiment in a completely randomized design with three replications. Factors of experiment inclu...

Effect of cobalt (Co) stress on morphological parameters and pigments of Arachis hypogaea L. were studied. Growth parameters such as, root and shoot length, number of nodules, total leaf area and root and shoot dry weights; photosynthetic pigments viz., chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll and carotenoid contents were analysed. Growth parameters and pigments have beneficial value...

To determine salinity-tolerant genotypes among the citrus germplasm present in Kotra collection, a greenhouse experiment was carried out as factorial, completely randomized design with three replications, at four levels of NaCl (0, 2, 4 and 6 dS/m) and 10 unknown genotypes, for 16 weeks. Cleopatra mandarin and Swingle Citromelo, as tolerant (control) and sensitive cultivars, respectively, were ...
