WebJan 17, 2024 · The proper control of mild soil drying in both rice and wheat during the later grain-filling period can enhance whole-plant senescence and the remobilization of carbon from vegetative tissues to grains, leading to better grain filling (Yang and Zhang, 2006). Therefore, it would be worthwhile practicing this method in the field using a variety ... WebMay 1, 2004 · Grain yield improvement of maize (Zea mays L.) hybrids has been associated with delayed leaf senescence.The objective of this study was to quantify the vertical profile of leaf senescence during the grain-filling period in an older hybrid (‘Pride 5’) and two more recent maize hybrids (‘Pioneer 3902’ and ‘Pioneer 3893’).
