Other claims from this paper (8)
- Observation Peach shoots and leaves expanded sigmoidally at all measured nodes.
- Observation The 12th leaf node reached half expansion relatively earlier than the sixth and 16th nodes.
- Observation Young peach leaves had low carbon dioxide assimilation rates reflected in chlorophyll concentration.
- Observation Net daily carbon dioxide assimilation was negative in young expanding peach leaves.
- Observation The peach leaf sink-to-source transition preceded full leaf expansion.
- Observation The 12th peach leaf changed from import to export after about 7-9 days at 38% to 52% expansion.
- Observation The 16th peach leaf changed from import to export after 9-10 days at 32% to 38% expansion.
- Mechanism Leaves below 30% to 50% expansion may themselves be sinks and may not meet sink demand.
