The physiological and biochemical responses of three ecotypes of Artemisia absinthium L. from Iran were evaluated under salinity conditions. Salinity treatments were made by NaCl with EC of 0, 5, 10 and 15 dS/m.   Physiological and biochemical attributes were measured 30 days after the salt treatments imposed. Highest reduction in the shoot and root fresh weights was observed in the ecotypes of...

Cumin (Cuminum cyminum L.) is one of the most important herbs and medicinal plants that allocate main part of medicinal plant export in Iran. This investigation was conducted to study the effects of drought stress on important agronomic traits of different cumin ecotypes from the major cumin cultivation of the country. Forty-nine ecotypes from different regions of Iran were planted in a simple ...

chamomile is a medicinal plant with high economic value. in this research, 20 chamomile ecotypes collected from different regions of iran were evaluated for genetic and chemical diversity. dna was extracted by ctab and polymerase chain reaction was performed using 13 rapd markers. essential oils extraction was performed by water distillation using clevenger system. components of the essential o...

fennel is one of the oldest herbs and possesses appealing flavor and beneficial medicinal effects. fennel(foeniculum vulgare mill.) belongs to the apiaceae family and its essential oil and seeds are used to flavor foods including meats, ice cream, candy, baked goods and condiments. the increasing commercial value of fennel necessitates the need to develop elite ecotypes with high essential oil ...

jujube (ziziphus jujuba mill.) is a valuable medicinal plant which is important in iranian traditional medicines. although the regional plants such as jujube play an important role in our economy, but they are forgotten in research and technology. considering the economic and medicinal importance of jujube, the first step in breeding programs is determination of the genetic diversity among the ...

identifying and selecting superior genotypes in native germplasm is one method for breeding fruit trees. five different ecotypes of jujube (ziziphus jujuba mill.) were collected from different regions of isfahan province, iran, for evaluation of their morphological and pomological traits during 2011-13. results showed that quantitative traits were more significant within ecotypes. ‘‘najafabad’ ...

seed dormancy has a critical role in ecological adaptation of wild plant species such as hordeum spontaneum, a wild relative of barley. in this study, 192 ecotypes of hordeum spontaneum maintained in national plant gene bank of iran (npgbi) originating from different climatic zones of the country were evaluated. morphological, phenological and physiological traits were recorded in the field. af...
