Summary
Abiotic
stress includes all adverse conditions for plant growth such as extreme either
high or low temperature, radiation, salinity, humidity, drought, heavy metals
toxicity, or all other unaffordable environmental conditions. Many previous
works studied the influence of abiotic stress treatments on growth, production,
gene expression, secondary metabolites and antioxidant enzymes of fruits and vegetables
crops. However, limited works investigated the effects of abiotic stress
treatments on quality, postharvest behaviour, storage ability, molecular
response, antioxidants and bioactive compounds content of fresh fruits and vegetables
crops.
The
main quality parameters of fresh products are color, flavour, texture, and
nutritive value. Color is mainly related to natural pigments such as
chlorophylls, carotenoids, and anthocyanins. Additionally, there are some
compounds such as volatile and non-volatile compounds which are mainly
responsible for flavour besides the taste. Pectic substances (the main
components of cell wall structure) and turgor pressure of cell wall are the
main two factors responsible for the texture. Nutritive value contains several
important chemical compositions for human health including sugars, organic
acids, minerals, antioxidants, phenolic compounds, and vitamins.
This
special issue aims to present works that include the influence of abiotic
stress treatments on the quality, molecular responses, postharvest behaviour,
bio-chemical changes, senescence, and storability of fruits and vegetables
crops. We welcome novel original research papers, short communications and
reviews which are concentrated on the physiological and molecular responses of fruits
and vegetables crops against all abiotic stresses.
