Meiotic behaviour and morpho-phenological variation in cut stock (Matthiola incana L.) flower
Morpho-phenological and meiotic studies were performed in twelve cultivars of Matthiola incana. All of the cultivars were diploid (2n = 2x = 14) with basic chromosome number x = 7.

Cytomixis in Pollen Mother Cells of Polygonum tomentosum Schrank.
Cytomixis, representing the migration of chromatic material from one cell to another, was observed in PMC's of Polygonum tomentosum Schrank. Cytomixis was observed at all stages of meiosis, but became less frequent in the later stages of meiosis. Direct nuclear fusion and cytoplasmic connections between cells were noted, so that a series of PMC's were ...

Cytomixis in Pollen Mother Cells of Spearmint (Mentha spicata L.).
Cytomixis was recorded during microsporogenesis in a tetraploid (2n=4x=48) genotype of spearmint (Mentha spicata L.), an aromatic plant of the family Lamiaceae. The phenomenon of cytomixis was observed in leptotene to pachytene stages of the first meiotic prophase. The migration of nuclear content involved all the chromosomes or part of the chromosomes
