บทคัดย่อ (EN): Heat tolerance of five strawberry cultivars, which have been recently introduced in Northern Thailand, namely “DN 1”, “NO.329”, “Pharajchatan 60”, “Akihime” and “Sachinoka”, were evaluated. Rooted runner plants which had 5-6 leaves (10 weeks old) of all cultivars were grown in the plastic house at Maejo University, Chiangmai, Thaialand. Twenty plants of each cultivar were then transferred to either 25/25 °C (control) or 39/29°C (high temperature condition) for 7 days. Heat stress condition caused statistically significant photoinhibition and low level of transpiration rate (E), stomatal conductance (gs ), CO2 assimilation rate (A) in all strawberry cultivars as compared with those plants grown in control condition. Among strawberry cultivars grown under heat stress condition, “Parajchatan 60” had markedly the lowest leaf temperature and percentage of electrolyte leakage (EC) than those other remaining cultivars. This study was also revealed that there was a significant relationship between EC and maximum quantum efficiency of PSII photochemistry (FV/FM), and gs and E. Hence, EC together with other indices related to the process of photosynthesis could be highly used as an index for selection of heat tolerant strawberries because EC showed more positive relationship with photosynthesis.
