Why LAI is different?

[KeLiu7]

In my simulation settings, I ensured sufficient water and nitrogen for both varieties. While their phenology shows only slight differences, their LAI patterns differ significantly.

Why does the LAI fluctuate (Is it because photoperiod and vernalisation?) and remain constant in the Baudin simulation?

In APSIMX Wheat or Classic, there is no fluctuation in LAI..

Could you please explain what might be causing this? Many thanks @HamishBrownPFR @hut104 @hol353 @ekhaembah @RobZys

Barley cultivars:

Baudin
[Phenology].MinimumLeafNumber.FixedValue = 9
[Phenology].PpSensitivity.FixedValue = 3
[Phenology].VrnSensitivity.FixedValue = 0

Dash:
[Phenology].MinimumLeafNumber.FixedValue = 10.66
[Phenology].PpSensitivity.FixedValue = 1
[Phenology].VrnSensitivity.FixedValue = 2.33
