Summary

The genusFlaveria contains C3- as well as C4- and C3–C4 intermediate photosynthesis species. This makes it an interesting genus for studies of the evolution of the C4-pathway of photosynthesis. Hybrids between species offer the possibility for studies of the inheritance of C4 traits. Four such cross combinations are described with regard to their morphology, leaf anatomy and CO2 gas exchange properties.

Zusammenfassung

In der GattungFlaveria kommen C3-, C4- und C3–C4-intermediäre Arten bezüglich des Photosynthesetyps vor. Das macht die Gattung interessant für Untersuchungen zur Evolution des C4-Weges der Photosynthese. Arthybriden eröffnen die Möglichkeit zur Untersuchung der Erblichkeit von C4-Merkmalen. 4 Arthybriden werden in bezug auf Morphologie, Blattanatomie und CO2-Gaswechsel beschrieben.

Краткое содержание

В родеFlaveria встречаются промежуточные виды, имеющие фотосинтез типа C3-, C4- и C3–C4-растений. Тем самым, ¶rt;тот род представляет интерес для исследования ¶rt;волюции пути фотосинтеза у C4-растений. Межвидовые гибриды дают возможность исследовать наследование признаков у растений типа C4. Описывается 4 межвидовых гибрида на основе морфологии, анатомии листа и газообмена CO2.
