This research was conducted in 2007 and 2008 cropping seasons in the experimental field of Shahid Salemi, Ahvaz, south west of Iran. In each year, the study consisted of a split split-plot experiment, using Randomized Complete Block Design (RCBD) with three replications. Four irrigation levels including irrigationoff at the 8 leaf, the 12 leaf and the tasseling stages and optimum irrigation wer...

Genotype × environment (G×E) interaction complicates the identification of superior genotypes. An understanding its causes is needed for a more effective breeding strategy. The objective of this study was to determine the plant traits that cause genotype × location (G×L) interaction for pod yield in peanut using a modeling approach. The CSM-CROPGRO-Peanut model was used to simulate pod yiel...

This study establishes a topographical framework for functional investigations on the regulation of lipid biosynthesis and its interaction with embryo photosynthesis in developing soybean seed. Structural observations, combined with molecular and functional parameters, revealed the gradual transformation of chloroplasts into storage organelles, starting from inner regions going outwards. This i...

Chlorophyll in plant cells is regularly accompanied by other pigments. For many years there has been speculation as to whether the light absorbed by these so called accessory pigments is utilized for photosynthesis. Engelmann's skillful experiments (1883) on algae of various colors, with motile bacteria as an indicator of photosynthetic activity, have been the basis of a general belief that the...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...

Cogongrass is one of the most destructive weed in China. It has been reported as one of the ten most troublesome weed species in the world. Therefore, developing an effective method to control this weed has become a significant and worthwhile practice. The effect of glyphosate on this weed growth was investigated during the 2009-2011 years. The photosynthesis, chlorophyll fluorescence, chloroph...

introduction drought stress is one of the most yield reduction factor of lima bean where effects on the more than 60% of bean world production. in this regard, solutions that help increase productivity with high water efficiency in this region can change the agricultural crop production. one of the solutions is using organic materials (acid humic). humic acid with linkage of water molecules and...
