in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...

studies manipulating the source-sink relationships during post anthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sinkor source-limited. the aim of this study was to determine source limitation degree of 36 iranian wheat cultivars andto investigate their intrinsic compensatory mechanism in response to source size reduction. a split plot design based o...

in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

source limitation during grain filling is important for both management and breeding strategies of grain crops. there is little information on the sensitivity of grain yield to various source-sink ratios in various wheat (triticum aestivum) cultivars. the objective of the current study was to evaluate the response of grain yield as well as yield components to different source-sink ratios during...
