MARS: cereal crops not yet sufficiently prepare for frost. The agro-meteorological Institute of the Commission (MARS) has in its most recent monthly edition the climate data in Europe then evaluated, whether and to what extent are sufficiently Hardy cereal crops . This involves adaptation process of plants with increasing cold to convert starch into sugar, which lowers the freezing point in the juice of the plant cells. In this way, the young shoots are protected from freezing up to-10%, and for a short time up to a certain point-5. Nationwide climate data of the western part of Europe showing across Europe starting from the North-Western parts of Poland to France and Spain, the cereal crops as well as trained not hardiness . On the South-Eastern part of Poland, Belarus, vast areas of Central and southern Ukraine is a weak partial winter hardness up to determine. These regions are particularly vulnerable because a cold wave is expected up to-20 degrees C. MARS is firmly that it must have been already Dewinterizing damage. An existing snow cover in the Ukraine has melted so far, that no sufficient protection function is to expect more. A final result will only be visible in the spring. Is an advanced and fully trained hardiness for the central regions in the Central District, southern, as well as in the Volga district of Russia's determined. To expect an increasing reduction of temperatures the weather reports in the next few days and weeks. If the plants have enough time to adapt to slowly descending degrees of cold hardiness in the other areas will arise. A sufficiently high snow cover, which protects the plants from cold winds and the very low temperatures is necessary in the long term.
