CONTROLLING SHOOT ELONGATION OF POTTED ALSTROEMERIA |
| Authors: | W. Healy, S. Klick |
| Abstract:
Although the alstroemeria cultivars available for containerized production are 50% sh orter than fresh cut cultivars, the plant height is still excessive for most markets. When planted on a monthly basis, plant height showed a cyclic pattern with the tallest plants developing during the spring and summer while the shortest plants developed during the winter. Spray treatments of Arest, Cycocel or B-Nine were only moderately effective in controlling plant height while Bonzi was the most effective. The number of days to flower was increased by up to 5 days when Bonzi was applied. The number of generative shoots was not affected by the growth regulator treatments, Plant height was reduced when plants were grown under 13+ hour photoperiods. The number of generative shoots was not affected by photoperiod. The number of vegetative shoots was related inversely to the length of the photoperiod. The number of days to flower decreased as photoperiod increased. | |
