LateGrainFilling
The LateGrainFilling phase in Chickpea represents the developmental period from LateGrainFilling to EndGrainFill. This phase represents the final portion of the grain filling period when seeds approach their maximum dry weight.
Overview
The GenericPhase model simulates the time between LateGrainFilling and EndGrainFill stages.
- This phase starts at LateGrainFilling and ends at EndGrainFill
- The model uses daily Thermal Time, retrieved from the
[Phenology].ThermalTimefunction - The Target thermal time is cultivar-specific
Late Grain Filling Process
During late grain filling:
- Grain filling rate declines as seeds approach maximum weight
- Seeds undergo final stages of reserve accumulation
- Moisture content in seeds begins to decline
- Most leaves have senesced
- The crop is approaching physiological maturity
