Postharvest investigations into chlorophyll fluorescence and low temperature injury in cut roses (Rosa hybrida L.) [PDF]

open access: yes, 2005
This is one of the first studies on the relationship between pre-harvest environmental conditions found in the Mediterranean and postharvest characteristics of cut roses (Rosa hybrida L. ).

Study of factors controlling the photoprotection capacity of the thylakoid membrane [PDF]

open access: yes, 2010
PhDPlants require light for the process of photosynthesis, but excess of light absorption can cause photooxidative damage. To avoid this damage, plants have evolved a photoprotective mechanism to dissipate excess light energy as heat in a process ...

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 ...

Deriving sun-induced chlorophyll fluorescence from airborne based spectrometer data [PDF]

open access: yes, 2010
Sun-induced chlorophyll fluorescence (Fs) is a promising parameter for remote measuring plant photosynthesis. It has been demonstrated that Fs at cell and leaf level is strongly related to photosynthesis.

Vertical distributions of chlorophyll in deep, warm monomictic lakes [PDF]

open access: yes, 2010
The factors affecting vertical distributions of chlorophyll fluorescence were examined in four temperate, warm monomictic lakes. Each of the lakes (maximum depth >80 m) was sampled over 2 years at intervals from monthly to seasonal.

Analysis of initial chlorophyll fluorescence induction kinetics in chloroplasts in terms of rate constants of donor side quenching release and electron trapping in photosystem II [PDF]

open access: yes, 2008
The fluorescence induction F(t) of dark-adapted chloroplasts has been studied in multi-turnover 1 s light flashes (MTFs). A theoretical expression for the initial fluorescence rise is derived from a set of rate equations that describes the sequence of ...

Can chlorophyll fluorescence imaging make the invisible visible?

open access: yes, 2021
Chlorophyll fluorescence has developed into a well-established noninvasive technique to study photosynthesis and by extension, the physiology of plants and algae.

CHLOROPHYLL a FLUORESCENCE ANALYSIS IN FORESTS

open access: yesAnnali di Botanica, 2016
A European-wide assessment of chlorophyll a fluorescence (ChlF, prompt fluorescence on dark-adapted samples) parameters in forest ecosystems was carried out in the years 2012-2013, within the 7FP FunDivEUROPE project. A total of 1596 trees growing in 209 stands distributed in six countries, from Mediterranean to boreal sites, were sampled.

Kinetic models of photosystem II should accommodate the effect of donor side quenching on variable chlorophyll a fluorescence in the microseconds time [PDF]

open access: yes, 2009
Quantitative data on laser flash-induced variable fluorescence in the 100 ns to 1 ms time range (Belyaeva et al. in Photosynth Res 98:105–119, 2008) confirming those of others (Steffen et al.
