Plant management of greenhouse roses. Flower cutting procedure

Flower-cutting technique of roses affects the production of succeeding crops. A comparison of different techniques was made using various cultivars. The principle factor affecting flower production was cane length. More flowers were produced from longer canes than are usually available with the method of cutting above the second 5-leaflet leaf. A second factor was cane-age. Cutting flowers below the flower joint with the carrying cane (“underhook cut”) resulted in decreased flower production when compared to an equal bud position of a younger cane. There were significant differences among cultivars in their response.
