Determination of zones of different plum growing period length in Serbia

Abstract

Zoning of Serbia territory was performed according to the length of active period of photosynthesis for plum cv. Pozegaca. Relations between thermal indicators of location and plum growing period length are examined. It was found that the length of growing period is of great extent, determined by the length of frost-free period, as well as by the mean annual air temperature and the mean air temperature for the growing period. The study was carried out using data from 55 phenological and 26 climatological stations in Serbia for the period from 1961 to 1995.
