Title: Effects of Duration of Shading on Growth and Development of Flowering Pot Plants
Abstract: Abstract Rosa hybrida and Saintpaulia ionantha were grown under three shading durations with set points of 200, 350 and 500 W m−2 and with a shade factor of 76%. The shading screens were closed approximately 46% at the longest duration and 22% at the shortest duration of the daily light period. The number of inflorescences and flower buds of R. hybrida increased with decreasing duration. In S. ionantha increasing duration increased number of leaves and improved leaf colour; however, leaf colour did not reach a commercially acceptable level. Canopy temperature was measured on Ficus pumila L., plants and significant differences between canopy temperature were obtained when the screens in three durations were closed. The water vapour pressure differences was significantly higher for the shortest duration when the shading screens was closed in the three durations.
