this research was conducted to study the effects of different salinity levels and exposure times on grain yield and yield components in a green-house experiment at gorgan university of agricultural science and natural resources during 2007- 2008 growing season. a factorial sand culture experiment with three completely randomized replications was used. salinity levels were -0.002, -0.25, -0.50, ...

there is little information available on morphological and agronomic traits, as well aschemical compositions of iranian mint landraces. this study was conducted to investigate themorphological, agronomic and oil content characteristics of iranian mint landraces using twelvelandraces, three of which belong to mentha longifolia, and the remaining, mentha spicata l, originatedfrom central regions ...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

The interactive effects of elevated [CO2] and drought on leaf photosynthesis, physiology yield in wheat (Triticum aestivum L.) are not well understood. This study evaluated the persistent stress (35–45% field water capacity) CO2 (ambient concentration + 200 ?mol mol–1) chlorophyll fluorescence, physiological indices, biomass, grain weight (in g m?2) two cultivars (large-spike cultivar Z175 mult...

an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...

     Triticum boeoticum wild wheat is a remarkable gene pool to environmental stress resistance. It is one of the most valuable species of the Triticeae tribe for improving wheat cultivars to moisture-stress. This research was carried out to assess the changes and responses of different traits of 10 accessions of Triticum boeoticum under non-stress and imposed moisture stress conditions in 2015...

evaluating of agronomic traits and their relationships with grain yield are important in plant breeding. in order to evaluate agronomic traits and their effects on grain yield, 76 durum wheat landraces as well as 4 local checks were studied in augmented design with 4 blocks under rainfed condition in maragheh and ardabil locations. the result showed that there is remarkable diversity among land...
