Pre-Symptomatic Detection of Viral Infection in Tobacco Leaves Using PAM Fluorometry

open access: yesPlants, 2021
Chlorophyll fluorescence imaging was used to study potato virus X (PVX) infection of Nicotiana benthamiana. Infection-induced changes in chlorophyll fluorescence parameters (quantum yield of photosystem II photochemistry (ΦPSII) and non-photochemical ...

Estimation of Chlorophyll Fluorescence at Different Scales: A Review

open access: yesSensors, 2019
Measuring chlorophyll fluorescence is a direct and non-destructive way to monitor vegetation. In this paper, the fluorescence retrieval methods from multiple scales, ranging from near the ground to the use of space-borne sensors, are analyzed and ...

Led induced chlorophyll fluorescence transient imager for measurements of health and stress status of whole plants [PDF]

open access: yes, 2011
We have developed LED (light emitting diode) induced fluorescence transient imaging instrumentation to image the plant health/stress status by calculation of two images: Fv/Fm (variable fluorescence over saturation level of fluorescence) and the time ...

Physiological Responses of Some Rootstocks and Interspecific Hybrids of Pistachio to Cold Stress under Greenhouse Conditions [PDF]

open access: yesJournal of Nuts, 2019
Cold is an environmental factor limiting the growth and yield of agricultural crops. To find cold-tolerant pistachio rootstocks, a factorial experiment was conducted at Pistachio Research Center (PRC), Rafsanjan, Iran during 2017-2018.
