The germination of Cola acuminata (P. Beauv.) Schott and Endl






Acta Horticulturae (49): 75-83

The germination of Cola acuminata (P. Beauv.) Schott and Endl

A study of factors influencing germination of Cola acuminata nuts showed that percentage germination and speed of germination rose with increase in nut size and increase in number of cotyledons. Nuts sown with the radicle facing upwards gave higher germination than those sown in other positions.

The two parental species and the hybrid all had 2n = 40. Meiosis was normal in C. acuminata but some chromosome pairing abnormalities were observed in C. nitida and in the hybrid (occurrence of univalents and trivalents). The parental species diff...

Polyacrylamide gel electrophoresis was employed to study the isoenzyme vari...
