摘要

Perilla (Perilla frutescens Britt.) plants with red colored leaves were grown under ultraviolet-B radiation (UV-B) of 0, 0.21, and 0.88 W m-2 at a constant photosynthetic photon flux of 200 micro mol m-2 s-1 provided by UV-B and fluorescent lamps, and an irradiation period of 16 h d-1. The leaf dry weight and leaf area of the plants were 19-23% and 14-19% smaller, and the concentration of anthocyanin (mg g-1 leaf DW) was 17-18% lower with UV-B than without, respectively. The concentrations of perillaldehyde and limonene (mg g-1 leaf DW), and the number of true leaves were not affected by the UV-B. The UV-B suppressed the growth and anthocyanin production, but had no effect on the concentrations of essential oil components in leaves of the plants.
