| Περίληψη: | Salvia hispanica L. (chia) microgreens are recognized as nutrient-dense crops suitable for controlled-environment agriculture but never been tested for space-related applications. Elucidating the physiological and biochemical responses of plants to ionizing radiation is essential for crop selection in space agriculture. Ground-based studies, employing irradiation of seeds with heavy ions as components of Galactic Cosmic Rays, are needed to identify radiation-tolerant crops suitable for long-duration missions. This study aimed to evaluate the effects of carbon (12C) and iron (56Fe) ions, on the morphological, anatomical, and biochemical traits of chia microgreens, as a candidate, emerging crop, for space cultivation. Dry seeds were irradiated with five doses (0.3, 1, 10, 20, and 25 Gy) of each ion type, and responses were assessed at the seedling stage. Distinct ion-specific and dose-dependent responses were observed across multiple functional traits. Iron irradiation promoted shoot elongation, photosynthetic pigment and soluble protein contents, whereas carbon ions increased seedling transpiration, nutrient accumulation (K, Mg, Ca), and polyphenol content, accompanied by notable anatomical adjustments in leaf tissues. Despite these structural and biochemical adjustments, net photosynthesis remained unaffected by irradiation treatments. However, P (Copyright © 2026 The Authors. Published by Elsevier Masson SAS..
