Abstract

Munkánkban összehasonlító vizsgálatokat végeztünk az őszi árpa fejlődési szakasza¬inak klimatikus igényeiről. A becsült meteorológiai jellemzők átlagosan nem mutatnak nagy változást a közeljövőre – jóllehet a század végére már igen –, de eloszlásuk alakulása a mezőgazdaságban komoly következményekkel járhat. A növény szempontjából azonban az éves és havi átlaghőmérséklet, illetve csapadékösszegek elemzése helyett sokkal több információhoz juthatunk, ha a növény fejlődési szakaszait külön-külön vizsgáljuk. Végigkövetve a növény fejlődési szakaszait megállapítható, hogy az őszi árpa klimatikus igényei várhatóan a jövőben is teljesülnek, jóllehet a termésbiztonság ezzel együtt romlani fog. ---------------------------------------- This paper covers comparative studies on the climatic needs of autumn barley in its individual development stages. The estimated average meteorology characteristics are not expected to change greatly in the near future – not until the end of the century - but changes in their distribution may have serious consequences for agriculture. For many plants, examining its needs in the various development stages separately is much more informative than examining its needs in terms of annual and monthly average temperature and precipitation levels. Monitoring the development stages of autumn barley leads to the conclusion that its climatic needs will most probably be still met in the future, although reliability of crop production will be compromised.
