In sugar beet (Beta vulgaris L.), taproot weight and sucrose content are the important determinants of yield and quality. However, high yield and low sucrose content are two tightly bound agronomic traits. The advances in next-generation sequencing technology and the publication of sugar beet genome have provided a method for the study of molecular mechanism underlying the regulation of these t...

Marine calanoid copepods colonize new habitats, and some become invasive. Their fitness, measured by intrinsic growth rate and net reproductive rate, is partially driven by biochemical processes. Thus, it is a function of ambient temperature. Biochemical processes may not be approximated well by yearly mean temperature alone when temperature cycles yearly, largely. Higher order moments may also...

in order to investigate the effects of single irrigation amounts at different stages of rapeseed growth on yield and the improvement of water use efficiency and water productivity indices, this experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 2002-2003 for rainfed spring rapeseed variety (pf.7015.91= sarigol) at maragheh...

in order to determine the best time of cotton irrigation in east of mazandaran province, an experiment, conducted for 3 successive years in agricultural research station of baykola. six treatments and four replications were carried out with randomized complete block designs for sahel variety. water treatments were carried out based on, i0: no irrigation, i1: once irrigation in boll opening stag...

chamomile (matricaria chamomilla l.) is one of the most important medicinal plants in iran. the main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. the experiment was conducted in the spring of 2010. the treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the aminol forte sprays (no spraying or contro...

Public agencies like the U.S. National Science Foundation (NSF) and the National Institutes of Health (NIH) award tens of billions of dollars in annual science funding. How can this money be distributed as efficiently as possible to best promote scientific innovation and productivity? The present system relies primarily on peer review of project proposals. In 2010 alone, NSF convened more than ...
