Identification of drought-resistant genotypes is crucial in order to reduce the negative effects of drought, as one of the most important limiting factors of crop production in arid and semiarid regions. Thus, effects of three irrigation regimes (irrigation after 50 (I1), 100 (I2) and 150 (I3) mm evaporation from a class A pan), as the main plot were investigated. These effects were studied on ...
This study was conducted to determine the suitable irrigation dose (0, 40, 80 and 120 mm) to compansate yield and bread-making quality of four common wheat varieties under the Mediterranean ecological conditions for two years. Grain yields of Pamukova, Sagittario, Fiorino and Golia ranged between 2864 kg ha (Golia, 0 mm) and 6021 kg ha (Sagittario, 80 mm). The supplemental irrigation caused the...
Extended Abstract Introduction and Objective: Due to the very high diversity among the genotypes of quinoa (Chenopodium quinoa), it has shown a very high adaptability and stability in different climates. Therefore, this experiment was performed to investigate the morphological and genetic diversity of 14 quinoa genotypes and compare them with the control genotype of the region (Titicaca). Ma...
genetic diversity is one of principle factors to succeed in breeding programs, so its determination is vital in the using of plant genetic resources. with the aim of evaluation of genetic diversity among safflower landraces, 20 lines (14 iranian and 6 foreign lines) were studied for phenotypic and genotypic variations using agro-morphological traits and rapd markers. field study was conducted i...
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...
This study aimed to evidence the best arrangement of plants according altitudes potentialize corn grain yield. An information survey was performed in 2019/20 harvest, using 144 producers responsible for production fields totaling 2,301.3 hectares environments Rio Grande do Sul. Within environments, 14 hybrids were arranged: DKB 240 PRO, DOW 2A620, AG 9045 PRO3, AS1555 AS1572 PRO2, AS1656, BIOGE...
To evaluate the effect of airborne dust on some physiological characteristics and yield of different wheat varieties, a field experiment was conducted at Research Farm of Razi University, Kermanshah, Iran in 2013. The evaluated treatments were washing and un-washing shoots of various wheat varieties including Pishgam, Zarin and Behrang. Measured traits were as relative water content (RWC), SPAD...
An experiment was conducted to study the effect of different methods of magnesium sulfate application and cultivar on yield and yield components of lentil (Lens culinaris Med.) under Khorramabad climatic condition. This experiment was a factorial based on a randomized complete block design with three replications performed at the Agricultural Collage of Lorestan University in 2008. Different me...
The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...
Heat stress causes morphological and physiological changes and reduces crop yield in rice (Oryza sativa). To investigate changes in phytohormones and their relationships with yield and other attributes under heat stress, four rice varieties (Nagina22, Huanghuazhan, Liangyoupeijiu, and Shanyou 63) were grown in pots and subjected to three high temperature treatments plus control in temperature-c...
