    Sterols of male and female compound inflorescences of Zea mays L. (1976)
    Springer
    Planta 133 (1976), S. 89-93 
    Details
    ISSN: 1432-2048
    Schlagwort(e): Zea mays ; Inflorescences ; Male ; Female ; Sterols

    Thema: Biologie
    Notizen: Abstract A comparison has been made between the sterols of male and female inflorescences and of pollen from Zea mays. The female inflorescence was shown to contain cholesterol, 24-methylcholesterol, 24-ethyl-5,22-cholestadien-3β-ol, 24-ethylcholesterol and (28Z)-24-ethylidenecholesterol. Themale inflorescence contained the same five compounds together with 24-methylenecholesterol. Pollen contained 24-methylenecholesterol as its main sterol together with lesser amounts of cholesterol, 24-ethylcholesterol, (28Z)-24-ethylidenecholesterol, 24-methylene-5α-cholest-7-en-3β-ol and 4α-methyl-24-methylene-5α-cholest-7-en-3β-ol.

    Sterols of male and female flowers of Cucumis sativus (1977)
    Springer
    Planta 134 (1977), S. 115-117 
    Details
    ISSN: 1432-2048
    Schlagwort(e): Female ; Flowers ; Male ; Meiosis ; Sterols
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Sterols of male and female flowers of Cucumis sativus L. were similar in composition. The principal compound was 24ξ-ethyl-5α-cholesta-7,22-dien-3β-ol. Five other 5α-Δ7 were detected: 24ξ-methyl-7-ene, 24ξ-ethyl-7-ene, 24-ethyl-7,24(28)Z-diene, 24ξ-ethyl-7,25-diene and 24ξ-ethyl-7,22,25-triene. Small amounts of Δ5 (cholesterol, 24ξ-methylcholesterol and 24ξ-ethylcholesterol) were detected. The possible significance of these sterols is discussed.

    A case of unusually early postpartum resumption of estrous cycling in a young female chimpanzee in the wild (1986)
    Springer
    Primates 27 (1986), S. 517-519 
    Details
    ISSN: 0032-8332
    Schlagwort(e): Pan troglodytes schweinfurthii ; Chimpanzee ; Female ; Estrus ; Lactational amenorrhea

    Thema: Biologie
    Notizen: Abstract A case of unusually early postpartum resumption of estrous cycling (〈7 months) was recorded for a young, presumably primiparous female in the M group of chimpanzees (Pan troglodytes schweinfurthii) in the Mahale Mountains National Park, western Tanzania. The female showed estrous cycling while lactating her infant, and mated with young and low-ranking males as well as with the alpha male.
