“…The quantitative effect of irradiation is shown by the inverse relation between pollen tube growth and dosage observed by PFAHLER (1971) for maize pollen, as well as by us for apple and pear pollen (Fig . 1) .…”

Apple and pear pollen was irradiated with doses of 0, 50, 100, 250 and 500 krad (gamma rays) and stored at 4°C and 0-10 % r .h. From the in-vitro germination percentages an average LD50 dose of about 220 krad was estimated . For both irradiated and untreated pollen a close and corresponding lineair relationship existed between germination percentage and pollen tube growth .Irradiated pollen was much more sensitive to dry storage conditions than untreated pollen, resulting in less germination and more bursting . Apparently, irradiation caused the pollen cell membrane to lose its flexibility faster than normal . Rehydration of dry-stored, irradiated pollen in water-saturated air restored germination percentages up to their initial levels . The importance of this procedure in germination trials is stressed .

“…This increased metabolic activity may be the reason for stimulation of tube elongation. Conversely, radiation-induced inhibition of tube elongation is the indication of damaged cell membrane (Brewbaker and Emery 1962, Pfahler 1971, Visser and Oost 1981. Compared to control, the frequency of relatively long pollen tubes was more in pollen given 10-50 Gy radiation.…”

“…Earlier BREWBAKER & EMERY (1962) determined for 20 species that pollen germination was only inhibited by X-ray doses of 220 kr or higher. In contrast, PFAHLER (1971) found an average LD50 at only 0.5 kGy in maize. The lethal dose varied considerably with the genotype (PFHALER, 1971).…”
