Implication

Randomized trial evaluates photosynthetic traits in Cannabis sativa, suggesting A/Ci curves outperform faster methods.

Key Points

The study aims to compare the accuracy of different methods for estimating leaf photosynthetic traits, particularly Vc max, for process-based modeling.
Evaluated RACiR and OP methods against traditional A/Ci curve in a two-year field experiment.
Utilized four Cannabis sativa varieties grown under various irrigation regimes.
Integrated derived photosynthetic traits into a coupled A-gs model for assessment.
A/Ci curve provided the most accurate gs simulations with R2 values from 0.55 to 0.84.
RACiR and OP methods resulted in gs overestimations of 26.7% and 50.7%, respectively.
A/Ci curves remained the preferred method under Mediterranean conditions for high accuracy in Vc max estimation.
