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.

β-Cyclodextrin-Based Nitrosoglutathione Improves the Storage Quality of Peach by Regulating the Metabolism of Endogenous Nitric Oxide, Hydrogen Sulfide, and Phenylpropane
Chen Chen, Shuhua Zhu
Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1091-1107, 2023, DOI:10.32604/phyton.2023.026331

Abstract Nitrosoglutathione (GSNO) and β-cyclodextrin (β-CD) exhibit positive roles in regulating fruit quality. However, there are few reports about the effects of GSNO and β-CD on enhancing storability and boosting nitric oxide (NO), hydrogen sulfide (H₂S), and phenylpropane metabolism in fruits during storage. “Xintaihong” peach were treated with 0.5, 1.0, 1.5 mmol L⁻¹ GSNO in 0.5% (w/v) β-CD solution (GSNO/β-CD). The effects of GSNO/β-CD on endogenous NO, H₂S, and phenylpropane metabolism were investigated. Treatment with GSNO/β-CD increased the color difference of peach and inhibited the increase of respiratory intensity, weight loss, and relative conductivity. Treatment with 1.0 mmol L⁻¹ GSNO/β-CD increased… More >

Response of Tomato Sugar and Acid Metabolism and Fruit Quality under Different High Temperature and Relative Humidity Conditions
Yanjiao Zheng, Zaiqiang Yang, Tingting Wei, Heli Zhao
Phyton-International Journal of Experimental Botany, Vol.91, No.9, pp. 2033-2054, 2022, DOI:10.32604/phyton.2022.019468

Abstract The combined stress of high temperature and high relative air humidity is one of the most serious agrometeorological disasters that restricts the production capacity of protected agriculture. However, there is little information about the precise interaction between them on tomato fruit quality. The objectives of this study were to explore the effects of the combined stress of high temperature and relative humidity on the sugar and acid metabolism and fruit quality of tomato fruits, and to determine the best relative air humidity for fruit quality under high temperature environments. Four temperature treatments (32°C, 35°C, 38°C, 41°C), three relative air humidity… More >
