Other claims from this paper (15)
- Intervention effect Sink limitation delayed soybean leaf senescence and abscission and produced stay-green leaves.
- Intervention effect Sink limitation inhibited soybean net photosynthetic rate shortly after treatment.
- Intervention effect Sink limitation did not affect initial soybean carboxylation rate shortly after treatment.
- Mechanism The initial decrease in soybean net photosynthesis was mainly attributed to stomatal limitation.
- Intervention effect The inhibitory effect of sink limitation on soybean photosynthesis weakened with time and became promotive.
- Observation Stay-green soybean leaves retained higher initial carboxylation rate at late growth stages.
- Observation Stay-green soybean leaves retained higher SPS, SuSy and SAI activities at late growth stages.
- Observation Stay-green soybean leaves retained higher photosynthetic pigment and soluble sugar content at late growth stages.
- Observation Stay-green soybean leaves retained higher starch, sucrose and fructose content at late growth stages.
- Intervention effect Sink limitation shifted soybean photosynthetic products toward vegetative organs.
- Intervention effect Sink limitation stimulated soybean stems and leaves to act as new sinks.
- Intervention effect Removing all pods and injuring seeds reduced soybean photosynthetic performance and carbon metabolism more than removing half the pods.
- Association Greater sink limitation produced more severe soybean green retention.
- Intervention effect Sink limitation significantly affected soybean carbon metabolism.
- Intervention effect Sink limitation maintained higher photosynthetic and key carbon metabolism enzyme activities in soybean at late growth stages.
