In order to better understand crossing barriers, we can follow the development of pollen after fertilisation. This is done through microscopy. Besides this we also offer determination of pollen viability and can do research on, for example, the effect of storage conditions on pollen viability.

The DNA amount as determined by flow cytometry will not always give direct information about chromosome number of the plant, especially for hybrids from parents with different chromosome sizes.

In order to support the interpretation of FCM results Iribov offers the service of chromosome counting. Cells of root tips or other tissue in the metaphase stage are isolated, stained, and analysed by microscopy to determine the number of chromosomes.
