This article analyses the organogenesis and flowering transition phases in Cerasus, Microcerasus, and Amygdalus. There are five phases identified for Cerasus fruticosa, C.vulgaris, C avium, Microcerasus tomentosa, and Amygdalus nana.

This article analyses the storage conditions for hybrid lily bulbs in the course of forcing. The authors come to the conclusion that taller plants are obtained after a three week storage at a constant low temperature. The time span between planting and flowering is 60—75 days. The optimal temperature for plant storage during forcing rages from 18 to 20 °С.
