SSR-based DNA fingerprints reveal the genetic diversity of Sicilian olive (Olea europaeaL.) germplasm

2005

Twelve published simple sequence repeat (SSR; microsatellite) markers, belonging to the ssrOeUA-DCA, GAPU and UDO series, were tested in a panel of 46 accessions of olive germplasm belonging to 30 unique cultivars collected in seven Provinces of Sicily. Four well-known reference olive cultivars were also added. The analysis was carried out on an automatic capillary sequencer using fluorescent dyes, and fragment sizes were determined using internal standards. The results allowed us to rank the SSRs assayed according to their information content and reproducibility. Up to 115 alleles were identified (119, if those unique to sport mutations were included), the frequency of which allowed geneti…

Improvement of FAO-56 Model to Estimate Transpiration Fluxes of Drought Tolerant Crops under Soil Water Deficit: Application for Olive Groves

2014

[EN] Agro-hydrological models are considered an economic and simple tool for quantifying crop water requirements. In the last two decades, agro-hydrological physically based models have been developed to simulate mass and energy exchange processes in the soil-plant-atmosphere system. Although very reliable, because of the high number of required variables, simplified models have been proposed to quantify crop water consumes. The main aim of this paper is to propose an amendment of the Food and Agricultural Organization (FAO) of the United Nations FAO-56 spreadsheet program to introduce a more realistic shape of the stress function, valid for mature olive orchards (Olea europaea L.). The mod…
