Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Plants are subject number of individual and combined stress factors. In response to stresses, changes are taking place in the organism aimed at reducing exposure and plant survival. The main mechanism of damage caused by abiotic stresses is the generation of reactive oxygen species such as superoxide radicals, hydrogen peroxide and hydroxyl radicals. Oxidative stress through increased ROS generation leads to oxidative damage in biological macromolecules. This review presents the eﬀects of high and low temperatures and drought on the morphological, physiological and cytological parameters of plants and oxidative stress as a result of stress factors.
