Earlier quantification of rice blast impact via instantaneous chlorophyll fluorescence [PDF]

open access: yesPlant Methods
Background Rice blast, one of the major diseases causing significant rice yield loss, downregulates the photosynthetic activity and induces aggressive spread of cell death causing food security concerns.

Chlorophyll fluorescence—a practical guide [PDF]

open access: yesJournal of Experimental Botany, 2000
Chlorophyll fluorescence analysis has become one of the most powerful and widely used techniques available to plant physiologists and ecophysiologists. This review aims to provide an introduction for the novice into the methodology and applications of chlorophyll fluorescence. After a brief introduction into the theoretical background of the technique,

Quantitative imaging of chlorophyll fluorescence [PDF]

open access: yesNew Phytologist, 1995
summaryA computer‐controlled video system is described where images of chlorophyll fluorescence from oat (Arena saliva L.) leaves are captured throughout an induction curve. The fluorescence parameters φ11 and ΔFm/F'm which represent photosystem II photochemical efficiency and non‐photochemical quenching respectively are calculated from images taken ...
