To evaluate the effect of water-deficit stress on the yield, antioxidant activity, and physiological traits of four Iranian melon genotypes (“Khatooni,” “Suski-Sabz,” “Zarde-Tabriz,” and “Shiari”), an experiment was conducted. The irrigation levels were: (1) control (100%ETc); (2) deficit irrigation 66% (66%ETc); and (3) deficit irrigation 33% (33%ETc). The results showed that the yield and rel...

Crop wild relatives adaptively diversified for environmental stresses are valuable resources for crop breeding especially for climate change scenarios, supposedly worsening drought and heat conditions. In this study, genetic variation of 54 barley genotypes comprised of 47 H. vulgare spp. spontaneum genotypes collected from west of Iran along with Reyhan cultivar and six F1 hybrids resulted fro...

Because of many small florets and protandry, cross pollination in onion which is a biennial plant, by using polycross method for breeding is suitable and easy. To produce polycross seed, bulbs of 9 self onion genotypes were planted in the shape of equilibrium lattice design for 9 treatments with 10 replications on May 2002. To study some agronomical characteristicss, the polycross seeds produ...

In order to study the effect of different levels of salinity and nitrogen (N) on physiological and biochemical reactions of two wheat genotypes at anthesis stage, a factorial experiment was performed as completely randomized design with three replications, in Research Greenhouse of Agricultural, Medical and Industrial Research School of Karaj‎‎ in 2011.‎ Treatments were two wheat cu...

  Quantitative traits and the response of 20 genotypes of soybean to water deficit stress were evaluated at Agricultural Research Station of Gorgan in 2010 and 2011. Therefore, 3 separate experiments were conducted, each experiment as randomized complete block design, in 3 replications. In the first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from evaporation pan...
