摘要

The prepared cultures can be used for plant protection. According to the method, parts of apple leaves - which have undergone winter hybernation - are washed and attached to the internal surface of the lid of Petri dish, the openings of the perithecias facing down. After the ascospores burst, the dish lid is pressed to the bottom and set to revolve for an hour at a speed of 2.5 rpm in the clockwise direction.
