Other claims from this paper (13)

Intervention effect Shading side leaflets during pod filling significantly increased photosynthesis in unshaded centre leaflets.
Association Higher photosynthesis under shading was associated with higher stomatal and mesophyll conductance.
Intervention effect The increased photosynthetic rates reversed within 2 days of shade removal.
Association Higher photosynthesis under side-leaflet shading was not associated with reduced low-oxygen enhancement.
Intervention effect Continuous side-leaflet shading reduced seed weight per soybean plant by 37%.
Intervention effect Shading only during the second half of pod filling reduced seed weight per plant by 28%.
Intervention effect Removing shades during the second half of pod filling reduced seed yield by 19%.
Intervention effect Shade removal delayed leaf senescence.
Intervention effect Continuous shading reduced seed number but left individual seed weight similar to controls.
Intervention effect Shading in the second half of pod filling significantly reduced individual seed weight while seed number was unchanged.
Intervention effect Shade removal in the second half of pod filling increased seed weight relative to continuous shading while seed number remained similar.
Observation Yield reduction under shading was less than proportional to the 63% loss of leaf area available for photosynthesis.
Mechanism Higher centre-leaflet photosynthesis and stem and lower-leaflet-surface photosynthesis contributed to whole-leaflet photosynthesis under shading.

Observation Nodules depended much less on fertilizer nitrogen than other soybean organs.
Observation The lower fertilizer nitrogen dependence of nodules was more evident in control plants.
Observation Soybean roots accumulated a higher percentage of fertilizer-derived than atmospherically fixed nitrogen regardless of salinity.
Association Fertilizer-derived nitrogen accumulation decreased as soybean plants matured.
Association Soybean pod accumulation of fertilizer-derived nitrogen increased toward maturity.
Intervention effect Soybean pod accumulation of both nitrogen sources was lower under salt stress, particularly at filling.
Intervention effect Salt stress decreased protein and free amino acid content in soybean pods.
Intervention effect Salt stress decreased sucrose and starch content in soybean pods.
