ABSTRACT: We analyzed plant production such as olive, grape and fig in several
Palestinian Occupied Territories, and studied the correlation analyses between
productions and climatic, bioclimatic features in the territory. This work
examines the following climate factors: average temperature, precipitation,
soil water reserve and water deficit; and bioclimatic parameters such as
compensated thermicity index, ombrothermic index and continentally index. The
data used were from nine meteorological stations of the Palestinian
Meteorological Department. The study was based on the correlation analyses
between olive, grape and fig production in nine plots: Hebron, Ramallah,
Nablus, Jenin, Jericho, Bethlehem, Jerusalem and Tulkarem over fourteen years. The analysis of variance revealed
a significant influence of the variables temperature and compensated thermicity
index on the production of olive and fig, and a low influence on grape
production. When we applied canonical correspondence analysis (CCA), the
Nablus, Jenin, Jericho and Gaza plots were most affected by the climate factors
as temperature, and bioclimate factors as compensated thermicity index,
whereas, the Hebron, Bethlehem, Jerusalem, Tulkarem and Ramallah plots showed
the influence of ombrothermic index, continentally index, precipitation, water
deficit and soil water reserve.
