Resumo: Stone pine (Pinus pinea) has been increasing its importance in the Portuguese national forest sector, due to the high value of its pine nuts. A better understanding of the growth process from tree structures namely twigs, leaves and cones is the main objective of this study. The study was conducted in grafted umbrella pine trees subjected to four treatments: control, irrigation, fertigation and fertilization, two accompanied with higher intensity (control and fertigation). The growth in length and diameter of the twigs, needles growth, litter fall, and biomass allocation, were intensely monitored monthly between April and December. Leaf water potential, soil moisture were monitored to evaluate the impact of summer drought stress. There were clear indications of the periods with highest growth rates in tree structures: twigs during spring until May and cones until June. Leaves appear in May and grow until October. Effect from fertigation was only important in needles growth and litter fall rate. The late start of the treatment application might explain the lack of response from other tree structures
