Application of zinc can improve the tolerance and resistance of plants especially sunflower to environmental stresses and be effective on kernel set and yield. To investigate the effects of zinc oxide nanoparticles on the length, effective period, the rate of kernel filling and kernel weight in sunflower cultivars, a factorial experiment based on randomized complete block design with three repl...
In order to study the relationship between grain filling rate, duration and leaf relative water content (RWC) and yield, an experiment was conducted at Rice Research Institute of Iran, as a randomized block design in Split Plot with 3 replications, in 2006. 5 irrigation levels as main factor (Continuously flooded, days after water banishment, 5, 8 and 11 day intervals immediately after 10 days ...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...
an experiment was conducted in order to evaluate the effects of humic acid spraying on grain yield and yield components of wheat, in agricultural research and natural resources center of tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irriga...
due to extent of zinc (zn) deficiency in soils of iran and its deficiency in human diet, this study investigated the effect of zn sulfate foliar applications (non-foliar application, 0.5 g/l at stem elongation stage, 0.5 g/l at stem elongation and grain filling stages, 0.5 g/l at stem elongation and 2 g/l at grain filling stages) on yield and its components (farm sector) and influence of grain ...
an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
