Light Intensity and Air Movement Effects on Leaf Temperatures and Growth of Shade-requiring Greenhouse Crops1

Year: 1969

Type: article

Abstract: Five greenhouse-grown shade-requiring plants, Saintpaulia ionantha, Philodendron cordatum, Sansevieria trifasciata, Codiaeum variegatum cv. Aucubaefolium and Begonia semperflorens were grown in sunlight at wind velocities from 0 to 4.4 mph. Necrotic areas developed on Saintpaulia leaves in sunlight at all wind velocities, although injury decreased as air velocities increased. Codiaeum, Philodendron and Sansevieria were more compact at increased wind velocities than those at recommended light intensities. Leaves of those species also became smaller as air velocities declined. Abnormal variegation developed on newly formed Codiaeum leaves at lowest rates of air movement. Largest chlorophyll contents were found in plants receiving recommended light intensities. Chlorophyll contents of plants in sunlight generally increased as rates of air movement increased.
