Sink Removal and Leaf Senescence in Soybean. Cultivar Effects

Key Points

• Leaf senescence is significantly affected by sink removal in soybean cultivars, indicating distinct physiological responses.
• Cultivars show differing patterns in leaf senescence rates following sink removal, measured over the growing season.
• Observational analysis across various soybean cultivars highlights the impact of cultivar on nutrient allocation and biomass production.
• Results suggest that understanding these cultivar effects may enhance soybean yield management strategies.
