Mechanical strength and anatomical structure of the peduncles of rose (Rosa x hybrida) flowers.

The anatomical differences between the strong flower peduncles of the rose cv. Mercedes and the weak peduncles of cv. Nubia were investigated. More supporting cells with thicker cell walls were found in the xylem elements and phloem fibres of Mercedes peduncles than in those of Nubia. Secondary growth was observed in the proximal zone of the peduncles of both cultivars. A complete ring of secondary thickening developed in the peduncles of Mercedes, whereas, in Nubia, the ring was incomplete due to the lack of interfascicular cambium. These differences were correlated with the postharvest tendency of peduncle bending in these 2 cultivars.
