This study was designed to compare leaf water potential (LWP) and grain yield responses to drought imposed during the grain-filling stage in several Japonica dryland (upland) and wetland (paddy) rice...
Effects of Ear Removal on Photosynthesis of the Flag Leaf during Grain Filling in Wheat
CO2 fixation system Ear removal Photochemical system Photosynthesis Ribulose-1
2009/8/5
In order to clarify the response of crops to sink restriction, we examined the effects of ear removal on photosynthesis of the flag leaf in wheat. For 11 days there was no difference in CO2 exchange r...
