AbstractEvaluates the effects of a new technology for long-day lighting on flowering of Rudbeckia hirta and Coreopsis grandiflora under commercial production. The new technology uses a stationary high-pressure sodium (HPS) lamp with an oscillating aluminum parabolic reflector. The HPS lamp can be used to efficiently deliver long-day, but flowering time was delayed and flower number reduced in some species when the maximum night interruption light intensity was less than 2.4 mu mol.m(-2).s(-1).
