Аннотация: The aim is to study the amount of phenological variability in northern marginal stands and the effect of annual temperature sums of the previous two years on the timing of flowering and on amount of pollen production. The geographical adaptability of the generative cycle to local climate. The efficiency of two temperature sum systems, a linear and curvilinear one was compared with simple calendar time as delineators of generative development.
