Abstract

Effects of shading on growth and flowering of zygocactus 'orange' was studied. The four levels, 0, 50%, 75% and 2 – layer of 50% shading were used for growing zygocactus. It was found that light intensity had effects on height, number of node, branching number, total leaves, flowering, flower size and shelf life. However, it showed no effect on number of flowers per plant. Growing zygocactus under 2 – layer of 50% shading yielded the greatest chlorophyll concentration and the least sugar concentration whereas those without shading tended to have greater starch concentration than others.
