Poinsettias for holiday trade: Henrietta ecke variety produces high quality blooms on schedule when grown under high light intensity
by Anton M. Kofranek
pp3-10, doi#10.3733/ca.v008n12p3
Abstract
Abstract not Available – first paragraph follows: The Henrietta Ecke double-type poin-settia–the most popular poinsettia pot plant variety in southern California– has the undesirable characteristic of losing the center bracts just about the time the plants are to be sold for the holiday trade. However, experiments have shown that the bract abscission can be prevented at this critical time if the grower takes proper precautions.
