Photosynthetic system parameters in STWs, their diploid parents and NTW under either NN or LN conditions after 30 days of treatment.

This dataset contains raw experimental measurements and calculated relative indices (RC) related to Photosynthetic system parameters ,including chlorophyll a (Chla), chlorophyll b (Chlb), Car, net photosynthetic rate (Pn), intercellular CO₂ concentration (Ci), stomatal conductance (Gs), and transpiration rate (Tr) of all lines under NN and LN stress, sampled at 30 days after LN treatment initiation (LN-30d).Statistical significance of genotypic differences was evaluated via one-way analysis of variance (ANOVA) followed by Tukey HSD tests.

Genotypes with significantly different mean values (P < 0.05) within the same treatment and time point are marked with distinct lowercase letters in the associated visualization files.
