On the world stage, the increase in temperatures due to global warming is already a reality
that has become one of the main challenges faced by the scientific community. Since …

Crop yields need to be improved in a sustainable manner to meet the expected worldwide
increase in population over the coming decades as well as the effects of anticipated climate …

In this investigation, the effect of salt stress on Portulaca oleracea L. was monitored at
salinity levels of 100 and 300 mM NaCl. At a concentration of 100 mM NaCl there was a …

The present study was carried out to investigate the effect of individual drought, heat, and
combined drought and heat stress on tomato plants. Combined stress resulted in the higher …

Salinity stress deleteriously affects the growth and yield of many plants. Plant growth
promoting rhizobacteria (PGPR) and chitosan both play an important role in combating …

The aim of this study was to evaluate the validity of some chlorophyll (Chl) a fluorescence
parameters as early indicators of a particular abiotic stress and also to characterize the effect …

Silicon (Si) is known to alleviate the adverse impact of different abiotic and biotic stresses by
different mechanisms including morphological, physiological, and genetic changes …

Objectives Chlorophyll-a fluorescence is an efficient tool to determine the photosynthetic
capacity of plants and the health status of plants under normal or stress conditions including …

Water deficiency significantly affects photosynthetic characteristics. However, there is little
information about variations in antioxidant enzyme activities and photosynthetic …

The climate has drastically changed over the past two decades. Rising temperatures and
climate change may lead to increased evapotranspiration, specifically soil evaporation …
