Morphology of artificial hybrids of Vriesea splendens x Tillandsia cyanea and V-splendens x Guzmania lingulata (Bromeliaceae)

摘要

lntergeneric hybrids Vriesea splendens x Tillandsia cyanea and V. splendens x Guzmania lingulata within the subfamily Tillandsioideae of Bromeliaceae were studied. Multivariate analysis of flower morphology and leaf and bract color place the intergeneric hybrids in relation to their parents, although the bract color resembled more that of the paternal parent. Other characteristics such as petal color and offshoot formation were not intermediate. Important flower characteristics for bromeliad taxonomy such as stigma type, petal appendages and pollen are discussed in relation to their parents. Pollen of the intergeneric hybrids was completely sterile.
