The PnET-Day model was independently parameterized to compare with estimated eddy covariance gross ecosystem production (GEP; gC m 2 day ) in a mature mixed hardwood and a mature red pine (Pinus resinosa) forest in Northern Wisconsin during the growing season of 2002 and 2003. The mature hardwood forest was dominated by Populus tremuloides, Populus grandidentata, Betula papyrifera, Quercus rubr...

for different agronomic traits in sunflower (helianthus annuus l.) inbred lines were estimated using “line × tester” analysis method. six new restorer lines were crossed with four cms lines as tester in 2006 growing season. the 24 f1 single cross combinations were planted in complete randomized block design with four replications in khoy field research station in 2007 growing season. there were...
