Modulating the chlorophyll a (Chl-a) fluorescence by all-trans-ß-Carotene (ß-Car) in the polarity and non-polarity solutions was investigated. The fluorescence intensity of Chl-a decreased as the concentration of ß-Car increased. The excited electronic le... see more

The complex of invasive species of phytophagous insects that can adapt to novel living conditions is constantly increasing. The ecological effect of their vital activity in the new environment is almost impossible to predict. As a result, invasions u... see more

The objective of this study was to find a rapid determination of the freshness of tomato (Solanum lycopersicum L.) and pepper (Capsicum annuum L.)fruits using portable chlorophyll fluorescence imaging instrument. To assess the fresh quality of tomato and ... see more

This study was carried out in the General Commission for Scientific Agricultural Research (GCSAR), Syria, at Der EzZour Agricultural Research Center, from 2008-2010, to examine the effect of salt conditions on some growth attributes and chlorophyll fluore... see more

Water and nutrients are the most yield limiting factors in fruit crops. Many studies have shown the chlorophyll (Chl) ?uorescence parameters provide good indicators of nutrient deficiency and stress. The effect of four foliar nutritive fluids considered a... see more

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 ... see more

Paper description:Salinity is one of the most serious agricultural problems that adversely affects growth and productivity of pasture crops.The effects of salinity on some ecophysiological and biochemical criteria associated with salt tolerance were asses... see more

3D front-face fluorescence spectroscopy and principal component analysis (PCA) were used to differentiate between Extra Virgin Olive (EVOO) and Olive Oil (OO). The results show that 3D front-face fluorescence could be an effective tool to characterize EVO... see more

In order to investigate the effects of some plant growth regulators on photosynthetic pigments and growth of fennel plants, a greenhouse experiment was conducted based on the randomized complete block design with three replicates in 2017. Treatments were ... see more
