Other claims from this paper (12)
- Intervention effect Reflectors initially increased TNC concentration in all vegetative tissues of soybean.
- Intervention effect After reflectors were removed, TNC concentration in pods and stems + petioles was lower in reflector-treated than in control soybean plants.
- Observation TNC concentration of pods and stems + petioles declined during seed development in soybean.
- Observation Leaf blades of soybean showed relatively little decline in TNC concentration during seed development.
- Observation Senescent leaf blades of soybean contained 9% or more TNC.
- Intervention effect Increasing reproductive load by 30% had little effect on leaf blade TNC in soybean.
- Mechanism Pods, stems and petioles act as major sources of stored carbohydrate for developing soybean seeds.
- Mechanism Stored carbohydrate in soybean leaf blades is relatively unavailable for supporting seed development.
- Observation From the standpoint of TNC content, the soybean plant appears capable of maintaining higher reproductive loads.
- Method / resource The hydrolytic enzyme extraction and ferricyanide analysis of soybean carbohydrates had superior precision, accuracy and recovery.
- Intervention effect Height, number of nodes and leaf blade dry weight were similar in control and reflector-treated soybean plants.
- Intervention effect Stem and petiole dry weight were similar in control and reflector-treated soybean plants.
