Phragmites australis is a cosmopolitan grass and often the dominant species in the
ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P …

The frequency and intensity of droughts have increased in recent decades, and climate
change is a major driver of global droughts. Among abiotic stress factors, drought is one of …

Aloe vera L. is one of the most important medicinal plants in the world. In order to determine
the effects of light intensity and water deficit stress on chlorophyll (Chl) fluorescence and …

Abstract γ-Aminobutyric acid (GABA) has high physiological activity in plant stress
physiology. This study showed that the application of exogenous GABA by root drenching to …

In recent decades, increasing human pressure has caused the gradual deterioration of the
physical and chemical properties of water and soil. Salinity is an important factor influencing …

Drought stress has multiple effects on the photosynthetic system. Here, we show that a
decrease of the relative contribution of the I‐P phase, ΔVIP=− VI=(FM− FI)/(FM− Fo), to the …

Accurate estimation of terrestrial gross primary productivity (GPP) remains a challenge
despite its importance in the global carbon cycle. Chlorophyll fluorescence (ChlF) has been …

Plant growth promoting bacteria (PGPB) endophytes that express 1-aminocyclopropane-1-
carboxylate (ACC) deaminase reportedly confer plant tolerance to abiotic stresses such as …

Detrimental effects of NaCl and NaHCO3 stress on tomato plants were compared. With
increasing stress intensity, accumulation of biomass in tomato shoots and roots significantly …

Plant growth, K and Na concentration, gas exchange, chlorophyll fluorescence parameters
and antioxidant enzymes activities were investigated in non-grafted, self-grafted and …
