Abstrakt: Abstract: InEquisetum arvense, apogamous sporophytes were produced on medium containing 510−6–510−8 g/ml kinetin. NAA, IAA, GA3, glucose and saccharose were ineffective for the induction of apogamy. On medium containing 510−7–510−8 g/ml kinetin, the gametophytes passed into sporophytic structures directly. On medium containing 510−6 g/ml kinetin, some gametophytes passed into sporophytic structures directly, and others became a callus-like cell mass from which an apogamoun shoot arose. The results of the morphological observations on them were reported and compared with the sexually produced sporophyes. The apogamous sporophytes induced by 510−7 g/ml kinetin were haploid in their nuclear phase and some of those induced by 510−6 g/ml kinetin had a tendency to become diploid.
