Abstract
Abstract Chrysanthemum morifolium Ramat ‘Fred Shoesmith’ was grown in a soil medium previously used to grow Easter lilies, Lilium longiflorum Thunb. ‘Ace’, treated with single drenches of a-cyclopropyl-a-(p-methoxyphenyl)-5-pyrimidine methanol (ancymidol) in early February and harvested April 26. Enough ancymidol was retained in the medium after 76 days of lily growth and 52 surface-irrigations to significantly retard chrysanthemum growth. Plant height after 10.5 weeks was about 12 and 29% less in media from 0.25- and 0.50-mg (active ingredient) ancymidol drench treatments, respectively, than in untreated medium. However, chrysanthemums grown in a new soil medium in new clay pots were about the same height as plants in new soil medium in pots from the 0.50-mg treatment, indicating that not enough ancymidol to retard chrysanthemum growth was retained in the clay pots.
