In order to investigate the effect of agrophysiologic traits of bread wheat cultivars to planting date, the present research was conducted on the basis of split plots experiment based on randomized complete blocks design with three replication during 2012-2013 at the research farm of Khuzestan Agriculture and Natural Resources Research Station. Three planting date mid-October, mid-November and ...
in order to determine traits which affected grain yield in optimal irrigation and terminal drought deficit conditions, a field experiments with 16 spring bread wheat genotypes as randomized complete block design with three replications conducted in neishabour during 2009-10 cropping seasons. results of combined analysis of variance showed, significant differences between many of traits vegetati...
To evaluate the grain-filling pattern, Chinese first super hybrid rice, Liangyoupeijiu was grown under tillage and establishment methods at a spacing of 20 cm × 20 cm with one seedling hill-1 and at a seeding rate of 22.5 kg ha-1 in Changsha, Hunan Province, China in 2012. Our results showed that, superior grain weight in TP had always higher than DS up to 24 DAH but at 36 DAH, grain weight had...
MicroRNAs (miRNAs) are upstream gene regulators of plant development and hormone homeostasis through their directed cleavage or translational repression of the target mRNAs, which may play crucial roles in rice grain filling and determining the final grain weight and yield. In this study, high-throughput sequencing was performed to survey the dynamic expressions of miRNAs and their correspondin...
in order to evaluation of nitrogen fertilizer application and seed inoculation by azotobacter and azosprillium on yield, rate and grain filling period of corn sc-500 cultivar, a factorial experiment was conducted based on randomized complete block design with three replications in farm of agriculture and natural resource research center of azarbaijan-e- shargi province in 2011. the factors were...
in order to study of effects of integrated biological and chemical fertilizers on fertilizer use efficiency, grain yield and related traits to grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...
It is well established that a high external NH(+) 4 concentration depresses many processes in plant development, but the underlying mechanisms are still not well understood. To determine whether the negative effects of high levels of NH(+) 4 are related to competitive cation uptake, wheat was grown in a field with moderate (18 g N m(-2)) and high (30 g N m(-2)) supplies of NH(+) 4 in the presen...
in order to evaluate plant density and cultivar effects on rate and process of grain filling, yield and yield components of three dry bean cultivars a factorial experiment (using r.c.b. design) was conducted in 1386 at agricultural and natural research center of east azarbaijan (tabriz). three cultivars (khomeyn, g-14088 and 11816) were planted at four densities (14, 20, 30 and 60 plants/m2) in...
The objective of this study was to estimate inheritance of the grain filling rate as indicator for heat tolerant genes. The minimum number of genes for the trait in bread wheat was also assessed by combining quantitative genetic estimates and SSR marker analyses. Two cultivars, Debra (heat-tolerant) and Yecora Rojo (heat-sensitive) crossed and F1 and F2 populations generated. The parents, F1 an...
