Other claims from this paper (19)
- Observation Most Bignoniaceae taxa are diploid with 2n = 40.
- Observation Dolichandra unguis-cati and Handroanthus chrysotrichus were polyploid with 2n = 80.
- Observation Tribes Jacarandeae (Jacaranda) and Tecomeae (Tecoma) had unusual chromosome numbers with 2n = 36.
- Observation Podranea ricasoliana had 2n = 38.
- Observation The basic number x = 20 is proposed for the Bignoniaceae family.
- Observation The average haploid karyotype length was 28.13 m.
- Observation Dolichandra cynanchoides had the shortest haploid karyotype, 18.63.
- Observation Dolichandra unguis-cati had the longest haploid karyotype, 37.63.
- Observation Type m chromosomes were the most common chromosome type.
- Observation One to five sm chromosome pairs were found in 16 species.
- Observation One st chromosome pair was found in Cuspidaria convoluta and Podranea ricasoliana.
- Observation The karyotypes of the Bignoniaceae species are symmetrical.
- Observation Asymmetry index A1 ranged from 0.11 to 0.23.
- Observation Asymmetry index A2 ranged from 0.14 to 0.22.
- Observation The karyotypes of Podranea ricasoliana and Cuspidaria convoluta are the most asymmetrical.
