Abstract:BACKGROUND: After transplanting, the recent abnormal low temperature caused physiological disorders of pepper seedlings. This study was conducted to evaluate the effects of UV-A LED, a physical elicitor, on the chilling tolerance of pepper seedlings. METHODS AND RESULTS: Seedlings were continuously irradiated with 370 and 385 nm UV-A LEDs with 30 W•m-2 for 6 d. After that, seedlings were exposed to 4°C for 6 h and then recovered under the normal growing condition for 2 d. There were no significant differences … Show more
