a field experiment was conducted at the seed and plant improvement institute research field station in karaj, iran, during the 2009-10 and 2010-11 growing seasons to estimate genetic progress and the variation in penological and agronomic characteristics in 13 irrigated facultative/winter bread wheat (triticum aestivum l.) cultivars released in iran between 1943 and 2011. trends of temporal var...

فرجی, ابوالفضل,

In the area with terminal heat and drought stress such as Gonbad, allocation of produced dry matter to reproductive organs is of great importance. In order to evaluate the effect of different temperature and moisture regimes on dry matter distribution and harvest index ofcanola an experiment wasconducted at Agricultural Research Station of Gonbad during 2005-2007. The experiment was a RCBD arra...

Elevated CO2 often increases grain yield in wheat by enhancing grain number per ear, which can result from an increase in the potential number of florets or a reduction in the death of developed florets. The hypotheses that elevated CO2 reduces floret death rather than increases floret development, and that grain size in a genotype with more grains per unit area is limited by the rate of grain ...

In order to investigate the seed vigor of corn hybrid 704 after maternal plant foliar application with methanol, some micro and macro-nutrients an experiment was conducted in a factorial form based on RCBD with three replications during growing seasons of 2010-2011. Treatments were four growth stages (the 8-10 leaves, the tasseling, the seed-filling, all the stages), seven levels of foliar appl...

plant photosynthetate partitioning is important in seed yield formation. in this research, in order to study grain filling procedure of chickpea in the presense of drought stress and nitrogen (n) fertilizer on remobilization rate, final grain weight and grain yield were measured. experiment was performed in an split-factorial using randomized complete block design with three replications. droug...

In areas with high rainfall distribution, proper irrigation management, including complementary irrigation, is one of the effective strategies to increase crop production. In order to investigate the effect of supplementary irrigation in different growth stages on the yield and water productivity of Autumn rapeseed, an experiment in the form of a complete randomized block design with five irrig...

A substantial increase in grain yield potential is required, along with better use of water and fertilizer, to ensure food security and environmental protection in future decades. For improvements in photosynthetic capacity to result in additional wheat yield, extra assimilates must be partitioned to developing spikes and grains and/or potential grain weight increased to accommodate the extra a...

MAIZE grain yield is shaped by source-sink relationships during filling. Such relations are driven complex metabolic changes, responsive to N availability and not fully understood. Here, the impact of limited sufficient fertilization on interconversions in ear leaf a new maize field-grown hybrid (Tzi8 × Mo17) its critical transition from assimilation remobilization were chronologically investig...
