Far-Red Supplementation Alters Leaf Morphology and Biomass Allocation in Greenhouse Tomato

Supplemental far-red radiation was applied to greenhouse tomato during the winter production season to assess morphological and yield responses. Treated plants exhibited longer internodes and larger individual leaves compared with...

Blue Light Fraction Modulates Anthocyanin Accumulation in Red Leaf Lettuce

Red leaf lettuce was grown under lighting treatments differing only in their proportion of blue photons. Pigment concentrations were quantified at multiple harvest points using spectrophotometric analysis. Anthocyanin content increased...

Daily Light Integral Requirements for Uniform Tomato Seedling Propagation

Tomato seedlings were propagated across a range of daily light integrals to establish targets for uniform, transplant-ready material. Growth uniformity was assessed using stem diameter, hypocotyl length and dry weight...
