Abstract: (125 Views)
This study investigated changes in biochemical characteristics of four ecotypes of milk thistle plants (Isfahan, Kohgiluyeh and Boyer Ahmad, Khuzestan-Umidiyeh, and Hungary) in response to three moisture levels (40, 60, and 80% of the maximum allowable depletion of available soil moisture) and five planting dates (September 27th, October 17th, November 6th, November 26th, and March 10th). The experiment was carried out at the research farm of Isfahan University of Technology, Iran, using a split-plot design and a randomized complete block design with three replications. Results showed that changes in planting date and irrigation regime caused significant effects on relative water content and the contents of proline, malondialdehyde, chlorophyll a and b, and carotenoids and the activities of antioxidant enzymes (catalase, ascorbate peroxidase, and guaiacol peroxidase) in milk thistle leaves. Ecotypes reacted differently to these changes, indicating varying sensitivities to environmental conditions. "Isfahan" and "Kohgiluyeh and Boyer Ahmad" ecotypes had the highest biological yield (11.5 kg/m2). Having the highest chlorophyll a, carotenoid, relative leaf water content, and quantum efficiency of photosystem II (Fv/Fm), "Kohgiluyeh and Boyer Ahmad" ecotype is recommended to be used in breeding programs to develop cultivars compatible with the country's climate. This research demonstrates that optimizing planting date and irrigation regime can enhance milk thistle crop yield, particularly under enhanced irrigation water demand caused by changing climate. Examining the relationship between plant biochemical characteristics and planting conditions highlights the potential value of these correlations for improving crop production management.
