Abstract
The cytological effects induced by the water extract from Cicuta virosa L. on the meiotic divisions in A. victorialis L. subsp. platyphyllum Hultén have been studied.
The most outstanding noxious effect on this water extract is occurredce of stickiness and clumping of chromosomes in meiotic divisions.
The sticky bridge, lagging and fragmentation of chromosomes at 1st and 2nd anaphase were found. And also, the alveolation at interkinesis could be observed (periods of treatment: 20 hrs.).
A. victorialis L. subsp. platyphyllum Hultén was strong and rapid.
