- W2074305195 abstract "The effects of pollen grain irradiation on pollen-tube mitosis were investigated. The data were obtained from artificial culture. For irradiation gamma-rays were applied with 137Cs 6, 000c at a dose rate 55kr/hr. The doses ranged from 0.5 to 100kr.1) Inhibition of mitosis increased with increasing dose; namely the higher the dose, the more reduced was the frequency of nuclear division and the more delayed was the time of its occurrence.2) In Lilium auratum the generative nucleus remained mostly undivided in showing chromosome elements even at 5kr, while at 20kr a few nuclei consisted of chromatin masses or chromosomes. The pollen-tubes of Lilium did not grow smoothly on the media. In natural condition, therefore, their pollen-tube mitosis may be more radio-resistant.3) At 80kr irradiation of Camellia japonica pollen the mitotic division of the generative nucleus was almost completely inhibited.4) In Camellia sasanqua the generative nucleus did not divide into 2 sperm nuclei above 25kr, while relatively many generative nuclei with chromosomes were observed at 50kr.5) The pollen grains of Impatiens balsamina had the highest radio-resistance. At 50-80kr the generative nucleus underwent complete mitotic division.6) Radio-sensitivity of pollen grains varied widely according to the species. In general, their pollen-tube mitosis was much more radio-resistant than the meiosis in PMC's and mitosis in root tips." @default.
