in order to study the effect of foliar zinc spraying on photosynthetic pigments and yield of chickpea under water stress conditions, a factorial experiment carried out based on randomized completely block design (rcbd) with three replications in university of mohaghegh ardabili agricultural research station in 2012. the treatments consisted of three levels of irrigation (irrigated at planting, ...
The present investigation envisages the in vivo measured laser induced chlorophyll florescence spectra of EMS (Ethyl methane sulphonate) treated safflower leaves. Seeds of safflower were treated with 0.5% EMS for three treatment durations (3h, 5h and 7h) to raise the populations. The effect of EMS treatment on chlorophyll content in the leaves was assessed using laser induced chlorophyll fluore...
Cyanobacteria are ecologically important photosynthetic prokaryotes that also serve as popular model organisms for studies of photosynthesis and gene regulation. Both molecular and ecological studies of cyanobacteria benefit from real-time information on photosynthesis and acclimation. Monitoring in vivo chlorophyll fluorescence can provide noninvasive measures of photosynthetic physiology in a...
In order to evaluate the effect of deficit irrigation and different types of potassium fertilizers on improving the photosynthetic pigments content and chlorophyll florescence parameters in rice (cv. Tarom Hashemi), two field experiments were conducted in the Rice Research Institute (Amol) and model farm located in Savadkouh in a split plot based randomized complete block design with three repl...
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Heterotrophic bacterioplankton abundance and production were determined along vertical (down to bathypelagic layers) and latitudinal (from 4.9 • E to 32.7 • E) gradients across the Mediterranean Sea in early sum...
Fluorometers are widely used in ecosystem observing to monitor fluorescence signals from organic compounds, as well as to infer geophysical parameters such as chlorophyll or CDOM concentration, but measurements are susceptible to variation caused by biofouling, instrument design, sensor drift, operating environment, and calibration rigor. To collect high quality data, such sensors need frequent...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
