辣椒(Capsicum annuum L.)用水杨酸(SA)喷洒植物，分别用6.1、5.8和5.7Wm(-2)的UV-A(320~390 nm)、UV-B(312 Nm)和UV-C(254 Nm)进行处理。UV显著降低了叶绿素(Chl)a和b以及类胡萝卜素(Car)的含量。SA处理减缓了UV-B和UV-C处理植株的Chl和CAR的减少。UV-B、UV-C和SA处理显著增加了植物体内的安替蓝蛋白、黄酮类、芦丁和紫外吸收化合物的含量。叶面喷施SA对辣椒的紫外线效应有一定的拮抗作用。
Pepper (Capsicum annuum L.) plants were sprayed with salicylic acid (SA) and treated with ultraviolet radiation UV-A (320-390 nm), UV-B (312 nm), and UV-C (254 nm) of 6.1, 5.8, and 5.7 W m(-2), respectively. UV significantly reduced contents of chlorophyll (Chl) a and b, and carotenoids (Car). SA treatment moderated Chl and Car reduction in plants treated with UV-B and UV-C. The quantity of antocyanins, flavonoids, rutin, and UV-absorbing compounds in plants that were treated with UV-B, UV-C, and SA were significantly increased. Foliar spray of SA counteracted the UV effects on pepper.
