POST-HARVEST DEVELOPMENT OF CUT TULIP FLOWERS1)
The senescent characteristics of cut tulips at 23.5°C were studied. The data show that tulips vary in vase-life from as little as 3 to 4 days to more than 6 days. Also, the stems and perianth of tulips continued to elongate after cutting. It was found that the last internode of the stem accounted for the greatest part of the elongation. This is a highly undesirable trait. On the other hand, the elongation of the perianth is desirable. Flower shape varied between cultivars. The overall water uptake pattern of cut tulips was similar, but large differences existed in the quantity of water absorbed. A set of standards for evaluating cut tulips is proposed.
