| Zusammenfassung: | The authors have cultivated in vitro microsporangia of Encephalartos altensteinii Lehm, observing the microgametophytes up to spermatogenesis.
The spermatozoids of Encephalartos Lehm, have been observed for the first time; they are two per microgametophyte, have a diameter of 150-180 [Jim and a pole clothed with flagella.
The genus Encephalartos is the first genus of cycads in which microgametogenesis has been induced in vitro. |
