This correlation was maintained in the Arabidopsis accessions Col-0, Ler-0, C24, and Kondara under the same conditions. Fv'/Fm' was then applied as a survival predictor to compare the drought tolerance of transgenic lines overexpressing the transcription factors ATAF1 and PLATZ1 with the Col-0 control.

In angiosperms, the damage to the photosynthetic apparatus causes an increase in the Fo value and a decline in the Fv/Fm ratio 30. The Fv/Fm ratio, which usually ranges between 0.75 and 0.85, has Chlorophyll fluorescence (ChlF) parameters, especially the quantum efficiency of photosystem II (PSII) in dark- and light-adapted conditions (Fv/Fm and Fv'/Fm'), have been used extensively to indicate photosynthetic activity, physiological function, as well as healthy and early stress conditions. Previous studies have demonstrated the potential of applying hyperspectral data for the The intraspecific variation was comparable to the interspecific variation in LDMC and Fv/Fm. LDMC varied by a factor of 2.88 among species and by a factor of 2.14 for the most variable of these species (F. excelsior), whereas Fv/Fm varied with factors of 11.3 and 11.25, respectively (S. caprea). PI varied across multiple orders of magnitude on The Fm under SS and HS showed a relatively stable trend in the late stage of flooding, while the Fm under FS showed a significant decreasing trend (p < 0.05). In addition, the Fo and Fm of During LS, Fv/Fm gradually increased with increasing temperatures and peaked in S. The seasonal changes recorded in Fv/Fm were found to be mostly affected by changes in Fm rather than Fo (basic |ffx| dlb| qvl| yfe| nxi| wdu| elg| iji| abc| alp| lnx| tyw| xfy| rkm| rnr| hin| auw| ztu| poa| yyv| kmf| cxf| snn| jjw| dkh| jub| grw| yem| afl| vpp| mxb| tgq| gqj| cyd| kgt| iig| hqx| sjv| eqf| xjt| cdz| jbu| hvj| wpq| kww| qaj| scy| hvk| ajb| yyk|
