Conteúdo: |
Pear trees grow irregularly in Brazil due to climatic conditions of mild winter. The main production area of temperate fruit crops in Brazil is located in the subtropical region, below 25°S, with high altitudes variation (from sea level to 1900 m), resulting in irregular dormancy adaptation phase. Variations in chilling accumulation are also observed throughout the years: less than 200 hours below 7.2°C during warmer years, or near 900 hours in colder years, in the same location. Low chilling cultivars required from 150 to 500 chilling hours below 7.2°C for flowering. If it occurs too early, such as in colder years, plants can be damaged by late frost resulting in large losses (near 100% depending on the cultivar). Research conducted under such conditions of mild winters indicates abnormal pattern of enzymatic activities, rootstock influences on dormancy progression, and morphological alterations in floral buds, necrosis, and abortion, resulting in productivity reduction. |
