Abstract/Contents:"Positive effects of UV-C radiation on plants were documented in previous literature with most about extending shelf life and reducing disease development. However, its effect on growth habits is scarcely reported in turfgrass. Here we provide evidence that the effect is dose-dependent, with lower UV-C doses (6 seconds and 1 minute daily) improving the performance of seashore paspalum (Paspalum vaginatum), as manifested by higher tiller density, reduced clipping yields as well as greater photochemical efficiency compared to control while higher doses (30 minutes, 6minutes daily) resulting in severe damages. Furthermore, the decline in seashore paspalums growth triggered by 1-minute UV-C radiation was probably associated with the decreased content of salicylic acid. Similarly, reduced clipping yields under 1-minute UV-C light were also seen in bermudagrass [Cynodon spp. (L.) Pers.]. However, this is probably mainly due to a decline in photosynthesis capacity, as reflected by decreased photosynthesis rate and percent green cover, plus an increase in jasmonic acid. Conclusions drawn from this project could offer a new perspective of the use of low dose of UV-C in turfgrass management."
