Effects of temperature during flower bud initiation and development in spray chrysanthemums grown with shading

, : Effects of temperature during flower bud initiation and development in spray chrysanthemums grown with shading. Research Bulletin of the Aichi ken Agricultural Research Center (20): 285-292

Various day/night temperatures were compared in a series of trials with cut-flower chrysanthemums grown in greenhouses with shades When the temperature exceeded 30 degrees C during the dark periods for short-day flower initiation, both initiation and flowering were delayed and there was an increase in the number of incomplete leaves without lateral buds. Both lateral shoots and internodes were longer than normal, flower formation was adversely affected and cut-flower quality was poor.
