[Development of pollen tubes in self-fertile and self-sterile lines of sugar beets in isolation].
Studies in pollen germination on stigmas of isolated plants showed a great difference in this process in different forms. A rapid and steady growth of pollen tubes, their accumulation near the micropyle and penetration in it are observed in self-fertile plants. Pollen tubes grow slowly, often forming thickenings and swellings in self-sterile forms. Some of them penetrate deeper, reaching sometimes the seedbud but turn back without penetrating into it.
