Abstract
Commercial-quality cut roses were produced in a single-stem production system from single node cuttings. About 1800 rose cuttings in seven sequential crops were identified from 7500 cuttings grown from Feb. through May, 1995. More than 70% of the cut stems harvested from these cuttings were 46 to 75 cm long. Longer stem roses had significantly more nodes and grew from lower, older nodes than shorter rose stems. Longer stem roses required significantly more days to flower harvest because the number of days to axillary bud break was longer than for shorter rose stems. The number of days for rooting, days from axillary bud break to visible bud, and days from visible bud to flower harvest were similar in longer and shorter rose stems. Axillary buds began to grow before rooting in shorter stems and began to grow a mean of 8 days after rooting in the longest rose stems.
