Chlorophyll fluorescence and hyperspectral reflectance were used to evaluate physiological responses to two common stressors in coastal environments. Chlorophyll content is one indicator of drought and salinity vegetation stress because of its direct role in the photosynthetic process and electron transport. Recent advances in fluorescence spectroscopy have led to the development of numerous re...

The use of traditional biocides to halt or reduce biodeterioration is increasingly deterred, due risks for human health and the environment, as well potential interference with stone materials. Alternative eco-friendly substances are needed limit these issues. Here we aim evaluate devitalization lichens by a new bio-based product: wood distillate (also known pyroligneous acid), by-product plant...

the use of chlorophyll fluorescence (chlf) technique was evaluated on nondestructive measurement of sugar content during fruit development. multivariate models, principal component analysis (pca), and partial least-squares regression (plsr), were developed for the classification and prediction of fructose, glucose, and sucrose in fig fruits. the results of this study showed a significant correl...

this study examined the phonetic characteristics of persian sentence stress produced by native mandarin chinese speakers. we compared the phonetic correlates of sentence stress, namely fundamental frequency (f0), vowel duration, and vowel intensity in the production of 8 mandarin chinese speakers and 8 native persian speakers. results indicated that mandarin chinese speakers of persian could di...

canopy temperature (ct) is used as a selection tool to improve crop adaptation to drought. the aim of this work was to investigate association of some photosynthetic characters with ct during grain filling in three cereal species. for this objective, a two-year study (2009-2011) was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, a...

in order to compare photosynthetic features of triticale, bread wheat, and barley under water deficit conditions, this experiment was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, and a new variety of barley were compared under well watered (ψsoil= -3 bars) and soil water deficit (ψsoil= -12 bars) conditions in a randomized compl...

Since chlorophyll fluorescence reflects the redox state of photosynthetic electron transport chain, monitoring of chlorophyll fluorescence has been successfully applied for the screening of photosynthesis-related genes. Here we report that the mutants having a defect in the regulation of photosystem stoichiometry could be identified through the simple comparison of the induction kinetics of chl...
