A Study of the Flower Biology of Different Rye Genotypes (S. cereale L., S. montanum Guss.)

摘要

In this study, the pollen germination rate, pollen viability, pollen size, pollen production and anther length of rye (S. cereale L.) and the diploid and tetraploid of perennial rye (S. montanum Guss.) populations were examined. The highest pollen germination rate was obtained in 30 % sucrose, 5 ppm boric acid and 10 ppm calcium nitrate solution with all specimens. Furthermore, the lowest pollen size (length: 18.92 m m; width: 15.26 m m), pollen production per anther (19982) and anther length (7.39 mm), but the highest pollen germination rate (40.48 %) and pollen viability (94.93 %) were observed in diploid perennial rye.
