Abstract

The article presents research results of Siberian larch microsporogenesis and microgametophytegenesis in the northern boreal forests (taiga) subzone. Duration of discrete microsporocytes meiosis stages has been ascertained,  disruptions during microsporogenesis were revealed. The microgametophytegenesis processes during pollen-grain formation are described. The pollen development abnormalities and experimental results of larch pollen sprouting   in vitro  are presented.
