摘要：
'Sonia' var rose ovules produced plants through in vitro culture after being pollinated with irradiated (gamma rays) pollen. A 500-Gy minimum dose was sufficient to inactivate pollen and induce in situ parthenogenesis; in vitro culture was necessary for embryo rescue. The dihaploid plants originated from small embryos which occupied only a part of the carpel cavity; they were clearly distinguished from tetraploid plants by miniaturization of all organs. The dihaploid plants were observed under glass-house conditions until flowering presented a normal gynoecium. They produced a small amount of pollen of reduced but regular size; growth and development were faster than the tetraploid controls in summer.
