Blankovskaya T. F., Kirilenko N. A.
Morphometric Analysis of Zygote during Its Maturation in Wheat and Rye
Cytology and Genetics 2002, v 36, number 3, 12-16
The size of cell, nucleus, and nucleolus was measured and the nucleus-to-nucleolus ratio was determined during zygote maturation in durum and soft wheat and rye under intravarietal pollination as well as under crossing of durum wheat with soft wheat and rye. The fluctuations of cell, nucleus, and nucleolus volumes during zygote maturation were observed. The curves percent ratio of these volumes to corresponding volume of egg cell have two peaks. There are differences between hybrid zygotes and parental forms in these indices.
