title: [Specific features of microsporogenesis in the hemp of the Shu valley].
abstract: Specific features of microsporogenesis were studied in the narcotic drug containing hemp of the Shu valley. Nuclear divisions were investigated from the moment of appearance of the archesporial tissue until the formation of mature pollen grains. A special attention is paid to the detailed cytological analysis of meiosis and defects at all meiotic phases. The defects at anaphase 1 and anaphase 2 did not affect the karyotype constancy and their absence at the tetrad stage can be considered as an evidence of cytological stability of the studied material.
