Establishment of Environmental Factors and Cultivation Conditions for Rapid Generation Advancement of Carthamus tinctorius L.

다국어 초록 (Multilingual Abstract)

Abstract - This study aimed to improve domestic safflower (Carthamus tinctorius L.) productivity by shortening the cultivation period and enhancing breeding efficiency. The experiment was conducted with four main groups: 1) a control group cultivated in an environment similar to a greenhouse, 2) photoperiod treatments (15 h, 18 h), 3) photoperiod + temperature (30°C) treatments, and 4) photoperiod + temperature + nutrient solution treatments. The groups were evaluated based on days to flowering (DTF), plant height (PH), leaf length (LL), leaf width (LW), number of branches (NB), and number of seeds (NS). As a result, it was confirmed that the group treated with a 15 hour photoperiod, 30°C temperature, and nutrient solution showed a shortened cultivation period and superior growth characteristics. These findings are expected to contribute to safflower generation advancement and productivity improvement, positively impacting stable and efficient safflower production in domestic agriculture.
