Summary
Hemp (Cannabis sativa) has re-emerged as a high-value multifunctional crop due to its agricultural versatility, industrial utility, and growing interest in medicinal and functional plant products. Recent regulatory changes and technological advances have accelerated hemp cultivation and utilization worldwide. However, sustainable expansion of hemp production requires deeper understanding of plant physiology, stress adaptation mechanisms, disease resistance, and the biosynthesis of bioactive compounds under diverse environmental conditions.
The aim of this Special Issue is to provide a comprehensive platform for presenting recent advances in experimental and applied hemp research, in alignment with the scope of Phyton – International Journal of Experimental Botany. This issue will highlight both fundamental and translational studies that improve our understanding of hemp growth, stress responses, and functional traits, while supporting sustainable agricultural and industrial applications.
The scope of this Special Issue includes, but is not limited to, the following themes: hemp physiology and development; abiotic and biotic stress responses; plant–pathogen interactions and disease management; metabolic pathways and bioactive compound biosynthesis; greenhouse and controlled-environment cultivation; functional plant materials and nutraceutical applications; breeding and genetic improvement; and smart agriculture technologies for hemp production.
By integrating experimental botany with applied crop science, this Special Issue aims to foster interdisciplinary collaboration and promote high-impact research in the global hemp research community.
