Chlorophyll Fluorescence Analyzer

叶绿素荧光仪

Stress often damages photosystem II before any visible symptom appears, which is why breeders and stress researchers rely on PAM fluorescence. This analyzer reports Fv/Fm, F0, Fm, NPQ and Y(II) using a 620 nm modulated LED and saturating pulses to 3000 µmol/m²/s. Plan for at least 20 min dark adaptation, and ask about the imaging option for whole-leaf maps.

Product Description 产品描述

Stress often damages photosystem II before any visible symptom appears, which is why breeders and stress researchers rely on PAM fluorescence. This analyzer reports Fv/Fm, F0, Fm, NPQ and Y(II) using a 620 nm modulated LED and saturating pulses to 3000 µmol/m²/s. Plan for at least 20 min dark adaptation, and ask about the imaging option for whole-leaf maps.

Highlights

  • Fv/Fm, F0, Fm, NPQ and Y(II) in one protocol
  • Fv/Fm resolved to 0.001 for subtle stress differences
  • Saturating pulse up to 3000 µmol/m²/s
  • Imaging add-on shows stress patterns over whole leaves or canopies

Applications

  • Drought, heat and cold stress research
  • Breeding for stress tolerance
  • Herbicide and pollutant effect studies
  • Post-harvest quality and storage trials
