Reactive oxygen species (ROS) are produced as a normal product of plant cellular
metabolism. Various environmental stresses lead to excessive production of ROS causing …

Flooding is detrimental for nearly all higher plants, including crops. The compound stress
elicited by slow gas exchange and low light levels under water is responsible for both a …

Global food production relies on irrigation, especially in low rainfall areas such as South
Africa. The study was conducted to determine the effect of drought stress on growth, yield …

Oxidative stress is induced by a wide range of environmental factors including UV stress,

Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was
carried out to investigate the effect of drought stress on proline content, chlorophyll content …

Effect of long term soil salinity was studied in wheat cvs, Kharchia 65 (tolerant) and KRL 19
(moderately tolerant) under control and two levels of salinity (ECe= 5.4 and 10.6 dS m− 1) …

Ascorbic acid (vitamin C) is an abundant component of plants. It reaches a concentration of
over 20 m M in chloroplasts and occurs in all cell compartments, including the cell wall. It …

Ascorbate is a major metabolite in plants. It is an antioxidant and, in association with other
components of the antioxidant system, protects plants against oxidative damage resulting …

Overall, drought and unfavourable temperatures are the major climatic limitations for coffee
production. These limitations are expected to become increasingly important in several …

Recent measurements of ozone levels have led to concern that the stratospheric ozone
layer is being depleted as a result of contamination with man-made chlorofluorocarbons …
