Scott D., Boyle T. H., Han S. S., Floral Development and Flower Longevity in Rhipsalidopsis and Schlumbergera (Cactaceae), HortScience, 1994, 29(8):898-900, doi: 10.21273/HORTSCI.29.8.898
Comparison of flower development and longevity in eight Rhipsalidopsis and five Schlumbergera cultivars under common chamber conditions. Perianth position, firmness, colour and stigma were assessed. Cultivars differed in the interval from opening to the onset of senescence. The material included forms with known and unresolved parentage.
