Special Issue Information

Dear Colleagues,

The current global climate change trend has had a substantial impact on the growth, yield, and quality of horticulture produce. The alterations in climate patterns and human activities give rise to diverse environmental conditions, such as heat, cold, drought, salinity, sodic and alkaline conditions, and heavy metal pollution. These conditions can significantly affect the productivity of horticultural crops. Various horticultural crops exhibit varying responses to abiotic stressors and are particularly vulnerable to abiotic stress, mainly during the early growth of seedlings, vegetative phases, reproductive stages (such as seed formation, blooming, and fruiting), and leaf senescence. Additionally, biotic stressors, such as nematodes, bacteria, insects, fungus, vectors, and viruses significantly impede the strength and production of horticultural crops.

The study of biostimulants compounds, hormones, new chemicals, and microbes in agriculture has shown that they may improve the ability of agricultural plants to withstand abiotic and biotic challenges, resulting in greater production in horticulture crops. Recent research has revealed that the novel phytochemicals, secondary metabolites, and antimicrobial peptides reduce the harmful effects of biotic and abiotic stresses by increasing the activity of antioxidants, both enzymatic and non-enzymatic, interacting with phytohormones, activating defense genes, and promoting systemic resistance.

In this context, we propose a research topic that will consist of original research, reviews, and methods articles. This compilation aims to provide a comprehensive understanding of the morpho-physiological, biochemical, and molecular mechanisms that enable horticultural crops to tolerate abiotic and biotic factors.

Momordica charantia (bitter cucumber) is a tropical and subtropical plant with a long history of use in traditional medicine. Salinity is a major problem that limits plant growth and biomass production. The aim of this work was to determine the salinity tolerance of bitter cucumber, through the spectral analyses of some metabolites involved in their response to abiotic stress factors. To carry out the experiment, two varieties of bitter cucumber and three experimental lines were subjected to saline stress by applying treatments with saline solutions in different concentrations (control—0 mM NaCl; V1—100 mM NaCl; and V2—200 mM NaCl). After applying the treatments, analyses were carried out on the amount of free proline (Pro), ascorbic acid, and aromatic amino acids. For proline and ascorbic acid, the tendency was for their concentration to decrease in the variants treated with saline solutions" with "the tendency was for their absorbance to decrease in the variants treated with saline solutions. The differences between the controls and the treated variants, as well as between the studied genotypes, highlight their capacity for resistance and adaptation to saline stress. Full article
