O.A. Gavrilova, O.A. Tikhonova. Diversity of pollen grain shapes, and their distribution across some grossulariaceae species and hybrids // Transactions of Karelian Research Centre of Russian Academy of Science. No 3. Experimental biology. 2013. Pp. 82-92
Keywords: pollen; apertures; exine; morphological type; hybrid; Grossulariaceae; Ribes
Pollen grains of 16 samples of 4 species and 2 tetraploid hybrids of the Grossulariaceae family were studied by light and scanning electron microscopy. Two morphological types of pollen were described and illustrated: 1st – 4-5-colpo-8-10-porate in genus Grossularia, and 2nd – 6-10-pororate in genus Ribes, as well as transitional forms of pollen grains found in species and hybrids. No increase in the pollen size was detected in tetraploid hybrids, but small-sized grains were present alongside with normal grains. All transitional pollen aperturate forms from meridionocolporate (gooseberry) to pantoporate (currants) were present in hybrids. Palynomorphological data support the isolation of the family Grossulariaceae DC and the subdivision of the genera Ribes L. and Grossularia Hill within the family.
