photoperiods and high light quantity (9–26 mol·m −2 ·d −1 ) only marginally improved flowering (0% to 15%) after 12 weeks of growth (B. Fausey and A.C. Cameron, unpublished data). Although growth at any temperature may result in flowering when given enough time

quantities that reached the French bean crop (DLI) were lowered by ≈1% and 11.5%, respectively, by the use of agronet covers. Covers block light as well as reduce the light quality ( Antignus and Ben-Yakir, 2004 ). The reduction in PAR and light quantity

vegetative growth in various crops ( Oren-Shamir et al., 2001 ; Shahak, 2008 ). In this study, shade nets modified light quantity (i.e., PAR ) received by bell pepper plants; the effect of shade net treatments on light quality was not measured. Black nets

50 estimates observed in Expt. 1 could be due to reduced light quantity and quality when the experiment was conducted (January for Expt. 1 vs. September for Expt. 2). In both experiments, LD 50 estimates were greater than GR 50 estimates, with GR

Higher plants respond to light quantity, quality, direction, and periodicity. There are numerous photoreceptors in plants, including chlorophylls, phtyochromes, cryptochromes, phototropins, and ones that react to green light ( Batschauer, 1999
