Table 1. Chlorophyll Contents, photosynthetic and chlorophyll fluorescence parameters in wild-type and yl1-1 mutant.
Pn (μmol CO2·m−2·s−1) | Gs (mol CO2·m−2·s−1) | Tr (mol CO2·m−2·s−1) | Fv/Fm | ΦII | |
---|---|---|---|---|---|
Wild type | 20.6 ± 0.41 | 0.79 ± 0.05 | 8.17 ± 0.28 | 0.78 ± 0.01 | 0.65 ± 0.01 |
yl1-1 | 17.3 ± 0.22** | 0.62 ± 0.08** | 6.99 ± 0.25** | 0.75 ± 0.01** | 0.60 ± 0.02** |
Data are presented as means ± SD (n = 6). The asterisk indicates significant difference between the wild type and yl1-1 mutant (Student’s t-test, *p < 0.05; **p < 0.01). Chl, chlorophyll; Pn, net photosynthetic rate; Gs, stomatal conductance; Tr, transpiration rate; Fv/Fm, maximum quantum yield of P SII; ΦII, effective quantum yield of PSII.
