The aim of the present work was to develop a method for the remote assessment of the impact of fire and drought stress on Mediterranean forest species such as the cork oak (Quercus suber) and maritime pine (Pinus pinaster). The proposed method is based on laser induced fluorescence (LIF): chlorophyll fluorescence is remotely excited by frequency-doubled YAG:Nd laser radiation pulses and collected and analyzed using a telescope and a gated high sensitivity spectrometer. The plant health…

Effects of Glyphosate-Based Herbicide on Primary Production and Physiological Fitness of the Macroalgae Ulva lactuca

The use of glyphosate-based herbicides (GBHs) worldwide has increased exponentially over the last two decades increasing the environmental risk to marine and coastal habitats. The present study

Monitoring Photosynthesis by In Vivo Chlorophyll Fluorescence: Application to High-Throughput Plant Phenotyping

In spite of the decrease in the rate of population growth, world population is expected to rise from the current figure (slightly above to 7.2 billion) to reach 9.6 billion in 2050. There is

Photosynthetic pigment laser-induced fluorescence indicators for the detection of changes associated with trace element stress in the diatom model species Phaeodactylum tricornutum

F685/F735 ratio and the deviations in wavelength emission maxima are clearly shown as adequate trace element stress indicators and P. tricornutum is shown as a promising biomonitor model species.

Making Sense of Light: The Use of Optical Spectroscopy Techniques in Plant Sciences and Agriculture

: As a result of the development of non-invasive optical spectroscopy, the number of prospective technologies of plant monitoring is growing. Being implemented in devices with different functions and

Laser induced fluorescence technique for environmental applications

We discuss the development of laser induced fluorescence sensors and their application in the evaluation of water pollution and physiological status of higher plants and algae. The sensors were built

Application of Laser-Induced Fluorescence in Functional Studies of Photosynthetic Biofilms

Biofilms are a ubiquitous form of life for microorganisms. Photosynthetic biofilms such as microphytobenthos (MPB) and biological soil crusts (BSC) play a relevant ecological role in aquatic and



Effects of drought on photosynthesis in Mediterranean plants grown under enhanced UV-B radiation.

It is predicted that increasing UV-B due to future stratospheric ozone depletion is unlikely to have any significant impact on the photosynthetic productivity of olive, lavender and rosemary in the field.

A rapid, non-invasive procedure for quantitative assessment of drought survival using chlorophyll fluorescence

The method presented here allows the acquisition of quantitative numerical estimates of Arabidopsis drought survival times that are amenable to statistical analysis and may complement detailed physiological and water relations studies.

Remote Probing of Plant Photosynthetic Apparatus by Measuring Laser-Induced Fluorescence

The method of lidar probing can be used for identifying tree species and assessing the condition of leaf and needle canopies and a persistent directly proportional dependence was found between the measured fluorescence signals and the chlorophyll content.

Photosynthesis in the water-stressed C4 grass Setaria sphacelata is mainly limited by stomata with both rapidly and slowly imposed water deficits

Results suggests that, although intrinsic mesophyll metabolic inhibitions occur, stomatal limitation to CO 2 diffusion is the main reason for the decrease in photosynthesis.

Photosynthetic responses of three C4 grasses of different metabolic subtypes to water deficit.

C4 plants are considered to be less sensitive to drought than C3 plants because of their CO2 concentrating mechanism. The C4 grasses, Paspalum dilatatum Poiret (NADP-ME), Cynodon dactylon (L.) Pers

Photosynthesis by six Portuguese maize cultivars during drought stress and recovery

The variation found among the cultivars tested suggests the existence of valuable genetic resources for crop improvement in relation to drought tolerance, and the most tolerant and the least tolerant cultivars to water stress were tested.

Laser-induced fluorescence of green plants. 1: A technique for the remote detection of plant stress and species differentiation.

These studies indicate that LIF measurements of plants offer the potential for remotely detecting certain types of stress condition and also for differentiating plant species.

Use of in vivo chlorophyll a fluorescence to quantify short-term variations in the productive biomass of intertidal microphytobenthos

A significant proportion of the hourly and fortnightly variability in the community photosynthetic light response was explained solely by variations in F0 associated with movements of microalgae, identifying migratory rhythms as the main cause for short-term variability in intertidal benthic primary productivity.
