Phytochemical constituents, such as total phenol, allicin and pyrovic acid as well as antioxidant activity of thirteen ecotypes of Allium hirtifolium Boiss. from different regions of Iran were evaluated. Average contents of total phenol, allicin and pyrovic acid of bulbs extracts per g fresh weight were 0.647 mg gallic acid equivalent (GAE), 2.127 mg and 84.412 µmol, respectively and antioxidan...

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 ...

in order to investigate the responses of sardari wheat ecotypes to drought stress, 12 spikes of sardari wheat were selected from different regions of kurdistan province and planted as head to row. in the second year, a split- plot factorial field experiment was conducted. in this experiment water stress and irrigation were considered as the levels of main factor and 12 sardari wheat ecotypes al...

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 ...

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...

selection of superior varieties of wide adaptability over diverse farming environments is of high importance, prior to any varietal recommendation. in order to study yield stability of alfalfa, 17 ecotypes were evaluated during 2004-2005 and 2005-2006 growing seasons at 10 research stations. each trial was carried out according to a completely randomized block design of 3 replications with fres...
