Modelling olive phenological response to weather and topography

摘要: Abstract A detailed analysis was made of the response olive floral phenology to climate and topography in southern Spain. Field phenological, topographical meteorological data collected at 12 sampling sites province Cordoba over a 17-year period (1996–2012) were statistically analyzed used model local phenological behaviour. The study sought determine: (1) optimal frequency during reproductive period; (2) major parameters governing phenology; (3) most influential variables. Findings for Sign test indicated that weekly yielded accurate results. Correlation multiple linear regression revealed altitude percentage eastward slope factors; positive correlation detected between delays phenophases onset increased orientation. partial least square identified air temperature, rainfall, crop evapotranspiration solar radiation as weather factors influencing phenology.
