wheat stem reserves can be an important contributor to grain particularly under decrease in the source strength through defoliation. the aim of this research was to study ability remobilization as important contribution on yield stability under drought conditions and to investigate their intrinsic compensatory mechanism in the wheat cultivars with different degrees of resource limitations under...

Increasing rice yield potential is essential to secure world food supply. The quantitative trait locus qTSN4 was reported to achieve yield increases by enhancing both source and sink capacity. Three greenhouse experiments and one field experiment in the Philippines were conducted to study near-isogenic lines (NILs) in two genetic backgrounds, subjected to treatments with restricted light resour...

Spring wheat cv. Minaret was grown under three carbon dioxide (C02) and two ozone (O3) concentrations from seedling emergence to maturity in open-top chambers. Under elevated CO2 concentrations, the green leaf area index of the main shoot was increased, largely due to an increase in green leaf area duration. Biomass increased linearly in response to increasing CO2 (ambient, 550 and 680 ppm). At...

in order to determine the effects of zinc foliar application on the vegetative characteristics, yield and fruit quality in strawberry (fragaria × ananassa duch) cv kordestan under salinity stress conditions, an experiment was carried out hydroponically in glasshouse as a controlled environment during 2009 through 2010. three levels of nacl (0, 15, 30 mm) and three levels of zn (0, 1.5, 3 g/l) w...

The pattern of senescence was studied by following the changes in chlorophyll and protein in the leaves and by measuring (32)P retention and export from source to sink during development of the rice plant (Oryza sativa L. cv. Jaya) subjected to different manipulative treatments. With the advance of reproductive development, the chronological sequence of leaf senescence was changed, so that the ...
