THE INFLUENCE OF CLIMATIC FACTORS AND TECHNOLOGY IN SOME POTATO VARIETIES GROWN ON SANDY SOILS
Less favorable conditions on sandy soils in southern Oltenia limited number of
species and varieties grown in the area. Drought and high temperatures in recent yearsÂ (maximum 430 C in air, ground 700 C) acted as dehydrating forces on plants, disruptingÂ their metabolism.
Very high air temperature in July and August at 30 to 38.40 C relative humidity decreasedÂ to 25%, high soil surface temperature and lack of rainfall during the growing season,Â producing an imbalance of the water balance of plants.
Excessive sweating can dehydrate plants leaf level, close osteolele and diminish gas
exchange in photosynthesis.
