Effects of gamma irradiation on in vitro pollen germination of different Cucumis species

Pollen grains of 14 Cucumis accessions were irradiated with 0, 1, 2, 3 or 4 kGy acute gamma rays and germinated in vitro directly afterwards. Pollen germination was significantly reduced by increasing irradiation dose for all species, except C. melo var. agrestis . Pollen tube growth was generally r...

Zusammenfassung:Pollen grains of 14 Cucumis accessions were irradiated with 0, 1, 2, 3 or 4 kGy acute gamma rays and germinated in vitro directly afterwards. Pollen germination was significantly reduced by increasing irradiation dose for all species, except C. melo var. agrestis . Pollen tube growth was generally reduced likewise. Pollen of two C. anguria subspecies was most sensitive to irradiation. Results show that the examined Cucumis species, especially C. melo var. agrestis , are sufficiently resistant to irradiation to be used as donor species for in vivo egg cell transformation of the cucumber.
