Other claims from this paper (11)
- Observation T. integrifolia had a diploid chromosome number of 28.
- Observation T. chantrieri had a diploid chromosome number of 22.
- Observation T. plantaginea had a centromeric formula of 22m+6sm.
- Observation T. chantrieri had a centromeric formula of 18m+4sm.
- Observation T. integrifolia had a centromeric formula of 28m.
- Observation Some T. chantrieri cells had four to eight additional small chromosomes, suggesting B chromosomes.
- Observation A satellite pair occurred on the short arms of chromosome pair VI in T. integrifolia and showed GC-rich staining.
- Observation The three Tacca species had a wide range of CMA- and DAPI-positive chromosome bands.
- Observation DAPI-fluoresced chromosomes were frequent in all three Tacca species.
- Observation The three Tacca species showed unique RAPD bands useful as species markers.
- Observation Karyotype and RAPD evidence indicated T. integrifolia is distantly related to T. plantaginea and T. chantrieri.
