Cytological characteristics of birch and alder pollen (different breeding forms) used in hybridization
Abstract Hybrids of some species of birch trees form completely sterile seeds (laboratory germination is zero in some hybrids, such as Karelian birch × Chinese white birch of inbred and outbred origin). It was noted analyzing the size distribution of birch pollen. Six size classes of pollen grains w...
