Turmeric (Curcuma longa L.) is a perennial rhizomatous plant from the family of Zingibraceae, native in South Asia. The main components of turmeric are curcuminoids and essential oil which are responsible for turmeric characteristic such as odor and taste. Due to the large areas of saline land in Iran and less information related to cultivation of turmeric, in this research, the effect of salin...

Two biochemical compounds of hydrogen peroxide and 24-epibrassinosteroid have significant biological effects on plant growth. In the present study, the effects of drought and its interaction with H2O2 and 24-epibrassinosteroid on the protein, sugars, essential oil percentage, photosynthetic pigments, phenols and flavonoids were investigated. For this purpose, a factorial experiment in a complet...

Carum copticum L. is a medicinal plant of the Apiaceae family with medicinal properties. In this study, the effects of UV-B radiation on the photosynthetic pigments and essential oils as well as phenols and anthocyanin of the seedling and callus of C. copticum were investigated under in vitro conditions. For this purpose, the experiment was set up in a completely randomized design, with three r...

Thymus daenensis is a medicinal plant endemic to semi-arid regions of Iran. A field experiment using a randomized complete block design with four replications was conducted to evaluate the effect of 20, 50 and 80% soil water depletion on morpho-physiological traits, essential oil content and composition and water use efficiency of T. daenensis during 2010-2011. Water stress reduced growth, ...

The objective of this study was to compare the influence of: genotype, environmental conditions and processing methods on levels of tocochromanols carotenoids and chlorophyll after maturation and harvesting in flaxseed oil from four varieties (Altess, Biltstar, Niagara and Oliwin). Oils were produced by cold pressing of dry seeds and seeds that were heated for 30 min at 60 °C. Temperature, suns...
