Abstract
We investigated a method of repairing inclined peduncles of next-to-top flower buds when the top flower buds were lost in cut-flower-growing of large-flowering chrysanthemum (Dendranthema grandiflorum (Ramat.) Kitamura). When the top flower buds were pinched in July, lateral buds near the top produced some leaves and then flowered in ‘Fukashinotakumi’. Peduncles of next-to-top flower buds inclined at 24.5-34.2° when leaves and tissues of the nodes were removed at the bottom of peduncles in the pinched plants. The inclination was reduced at 9.1-15.2° by removing leaves and tissues at the nodes that attached the next-to-top flower buds, by removing the remaining peduncles of the top flower buds. Combination of the two removal treatments effectively reduced the inclination. Removal time did not affect the degree of the inclination reduced by the combination of the two removal treatments. in ‘Madobe’ and ‘Seiun’.
As a result, it is possible to repair inclined peduncles of next-to-top flower buds by removing leaves and tissues at the nodes that attached the next-to-top flower buds, by removing the remaining peduncles of the top flower in large-flowering chrysanthemums.
