Vegetative
The Vegetative phase in Chickpea represents the developmental period from Emergence to EndJuvenille. This phase covers the early vegetative growth period before the plant becomes responsive to photoperiod for floral initiation.
Overview
The GenericPhase model simulates the time between the Emergence and EndJuvenille stages.
- This phase starts at Emergence and ends at EndJuvenille, when the juvenile phase is complete
- The model uses daily Thermal Time, retrieved from the
[Phenology].ThermalTimefunction - The Target thermal time is cultivar-specific and represents the duration of the juvenile period
Juvenile Phase
The juvenile phase in chickpea is the period during which the plant is insensitive to photoperiod for the induction of flowering. During this phase:
- The plant focuses on vegetative growth
- Leaf area development is rapid
- Root system establishment occurs
- The plant is not yet responsive to day length cues
Only after completing the juvenile phase does the plant become sensitive to photoperiod, which then influences the transition to reproductive development.
