Abstract

The morphologically unusual blind phenomenon which is found exclusively in Chrysanthemum morifolium Ramat. cv. Tenryu-no-asa widely grown for cut flowers, was shown to occur depending mainly on light intensity and duration of the vegetative growth phase.
With decrease of light intensity below 60% of full day light, almost all of the flower buds stopped their growth and become blind.
These results were peculiar to ‘Tenryu-no-asa’, and was not found in other cultivars tested.
