drought stress is the most important environmental constraint contributing to grain yield instability of maize(zea mays l.). evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. this study was conducted to estimate grain yield stability of maize hybrids and to identify hybrids th...

The aim of this study was to compare the number of inactivated-influenza vaccine-related spontaneous abortion and stillbirth (SB) reports in the Vaccine Adverse Event Reporting System (VAERS) database during three consecutive flu seasons beginning 2008/2009 and assess the relative fetal death reports associated with the two-vaccine 2009/2010 season. The VAERS database was searched for reports o...

Respiratory syncytial virus group A strain variations of 28 isolates from The Netherlands collected during three consecutive seasons were studied by analyzing G protein sequences. Several lineages circulated repeatedly and simultaneously during the respective seasons. No relationships were found between lineages on the one hand and clinical severity or age on the other.

During the investigation of fungi associated with black (sooty) head mold of wheat and barley in different regions of Golestan, Alborz and Qazvin provinces (Iran) in growing seasons of 2014–15, several isolates with typical characteristics of the genus Harzia Costantin were collected. Based on the morphological characteristics, all isolates were identified as H. acremonioides (Harz) Costantin. 

Abstract Wheat is the major agricultural crop in Iran. Using reliable tools to estimate wheat grain yield may help regional planners and stakeholders employ proper cultivation approaches increase different regions. The process-based growth models are essential analytical for representing main interactions between environment, crop, resources, production. For these reasons, have been used as an ...

this study was conducted under ahvaz, iran environmental condition during 2012 and 2013 growing seasons in order to investigate the influence of foliar application of potassium on some physiological and biochemical characteristics of three olive cultivars including ‘mission’, ‘koroneiki’ and ‘dezfuli’. potassium sulfate in different concentrations of 0, 1, and 2 g l-1 was sprayed twice on selec...
