Summary of ultraviolet (UV) effects on seed and seedling performance.

Species	UV applied	Effects described	Reference
Lactuca sativa	UV-C	Enhanced NaCl stress tolerance.	Ouhibi et al., 2014
Phaseolus vulgaris	UV-C	Increased germination rate. Increased accumulation concentration of bioactive molecules in seed coats.	Guajardo-Flores et al., 2014
Vigna radiata	UV-C; UV-A	Increased germination rate and seedling vigor. Seedlings with reduced susceptibility to root infecting fungi.	Hamid and Jawaid, 2011; Siddiqui et al., 2011
Arachis hypogaea	UV-C	Increased germination rate and seedling vigor. Seedlings with reduced susceptibility to root infecting fungi.	Siddiqui et al., 2011
Vigna mungo	UV-B	Exposure of hydrated seeds significantly reduced germination, suppressed the synthesis of photosynthetic pigments, as well as, root, and shoot development. Curling and twisting of the seedlings.	Shaukat et al., 2013
Carthamus tinctorius	UV-B	Enhanced germination rate but subsequent growth of the seeedlings is hampered.	Farokh et al., 2010
