Light curve parametrization of three rice (<i>Oryza sativa</i> L.) cultivars based on mechanistic models.

ABSTRACT: This study aimed to assess variations in leaf gas-exchange characteristics, leaf pigment contents, and some intrinsic traits of photosynthetic pigment molecules in three rice cultivars (cv. JR3015, Wufengyou3015, and Jifengyou3015) using mechanistic models. The findings revealed that chlorophyll content varied significantly among the three cultivars, but not maximum electron transport rate. JR3015 had lower chlorophyll content but the highest eigen-absorption cross-section (σ_ik) and the lowest minimum average life-time of photosynthetic pigment molecules in the excited state (τ_min). Our results suggested that the highest σ_ik and the lowest τ_min in JR3015 facilitated its electron transport rate despite its lower leaf chlorophyll content. Furthermo
