“…Garlic is a sterile crop and is reproduced vegetatively using cloves. Despite the lack of sexual reproduction, a long history of cultivation coupled with its environmental adaptation capacity and phenotypic plasticity resulted in a wide range of ecotypes through spontaneous mutations [ 14 ]. Vegetative propagation reduces breeding possibilities, giving more importance to physiological characterization for cultivar selection [ 15 ].…”

The impacts of global climate change and a rapid increase in population have emerged as major concerns threatening global food security. Environmental abiotic stress, such as drought, severely impairs plants’ morphology, physiology, growth, and yield more than many other environmental factors. Plants use a complex set of physiological, biochemical, and molecular mechanisms to combat the negative effects caused by drought-induced stress. The aim of this study was to investigate morphological, spectral, physiological, and biochemical changes occurring in 30 garlic accessions exposed to short-term drought stress in a greenhouse setting and to identify potential early drought-induced stress markers. The results showed that, on average, garlic plants exposed to drought conditions exhibited a decrease in assimilation, transpiration, and stomatal conductance of 39%, 52%, and 50%, respectively, and an average increase in dry matter and proline content of 10.13% and 14.29%, respectively. Nevertheless, a significant interaction between the treatment and accessions was observed in the investigated photosynthetic and biochemical parameters. The plants’ early response to drought ranged from mild to strong depending on garlic accession. Multivariate analysis showed that accessions with a mild early drought response were characterized by higher values of assimilation, transpiration, and stomatal conductance compared to plants with moderate or strong early drought response. Additionally, accessions with strong early drought response were characterized by higher proline content, lipid peroxidation, and antioxidant capacity as measured by FRAP compared to accessions with mild-to-moderate early drought response.

This paper offers an insight on present status of on-farm conservation of landrace diversity in the European Union. The review initially examines the types of materials that are the object of on-farm conservation, assesses the current status of maintenance and reproduction within farms and gardens, explores the motivations that drive ongoing conservation efforts as a foundation for future enhancement and identifies the key actors involved and their respective roles. Secondarily, it reviews European Union policies and their provisions supporting the conservation of crop diversity in the fields, with a particular focus on regulations pertaining to the commercialization of landrace seeds. Given that the availability of propagation material remains a primary constraint to the widespread dissemination of landraces, the review also includes current achievements and identifies constraints that could be mitigated. The discussion highlights how to continue and intensify the development and implementation of agro-environmental and seed policies as well as how further collection, documentation, study and promotion of the traditional farmers’ knowledge ̶ associated with the development, production and utilization of the traditional local products ̶ can improve the present situation. It is hoped that the model applied in the European Union could be also useful in other regions of the world.
