Use of pollen to identify cattail(Typha spp., Typhaceae) taxa inIndiana

摘要

Cattail (Typha spp.) hybridization in the U.S. has resulted in their large-scale proliferation in wetlands. Even though recent DNA fingerprinting methods have been developed to identify the taxa, the cost and time to identify them using microsatellite analysis has restricted widespread application of the technique. Pollen morphology can be used as a tool to identify cattail hybrids and the putative parents since the pollen forms are distinct for the species and hybrids. Monads are singular pollen shed during anthesis by T. angustifolia; T. latifolia sheds pollen in tetrads, which are units of four pollen.
