An investigation of the self- and inter-incompatibility of the olive cultivars 'Arbequina' and 'Koroneiki' in the Mediterranean climate of Sicily

In this investigation, the self-(in)compatibility of the Spanish cultivar Arbequina and the Greek cultivar Koroneiki was studied for the first time in Sicily, where these low vigour cultivars were recently introduced in super-intensive olive groves. Self- (S.P.) and openpollination (O.P.) tests, observation of fruit set and paternity test of seeds with microsatellite (SSR) markers, were performed to ascertain whether these cultivars were self-fertile and/or inter-compatible. For S.P. tests, branches with flowers at the balloon stage were bagged. For the O.P. tests, flowers were left to pollinate under natural conditions. Fruits from S.P. and O.P. were collected in November and fruit set was…

Modeling seasonal branch carbon dynamics in pistachio as a function of crop load

A simplified model for the prediction of carbon balance was developed to elucidate the seasonal trend of sink-source relationships in bearing and non-bearing pistachio (Pistacia vera L.) branches. Seasonal changes in growth rate of vegetative (leaf and shoot) and reproductive (infructescence) organs were monitored in branches of mature rainfed pistachio trees during the entire growing season (April–September). Simulations from the model were used to gain understanding of the implications of crop load on branch carbon (C) depletion and alternate bearing. Results showed that the pistachio branch was energetically able to sustain up to two infructescences (∼28 fruits) having a slightly positiv…

Histological studies on pistacio vegetative organs as related to fructification

Histological Studies on Pistachio Vegetative Organs as Related to Fructification Effects of fruiting on histological structure and histochemical characteristics of shoots, leaves and roots of pistachio (Pistacia vera L.) were microscopically examined on tissues sampled from trees with different crop-loads and carbohydrate reserves availability (bearing, non-bearing and trees subjected to inflorescence-bud removal twenty days before full bloom for four consecutive years). Differences in cambium activity and xylem and phloem structure in several developmental stages are reported. Starch content was higher in “deblossomed” than in non-bearing and bearing trees.

Growth, Phenology, Production and Oil quality of the Cultivar Arbequina in high-density hedgerow in four different areas of Italy

The success of the traditional olive-growing sector in EU countries – characterised by high production costs and a low selling price for the oil – was mainly determined by EU subsidies available for the sector. With the opening of the "free trade" area and a cut in subsidies in 2014, crucial changes in the sector are now needed. In order to increase the competitiveness of EU olive production, attention should be given to new high-yielding, mechanized cultivation systems. In the 90s, Spain introduced new high-density planting systems (1,200-2,000 plants/ha) using three low-vigour and early-fruiting cultivars (‘Arbequina’, ‘Arbosana’ and ‘Koroneiki’). Italian olive production lies in a geogra…

Intra-cultivar Diversity in sicilian and calabrian olive (olea europaea L.) Cultivars Depicted by Morphological Traits and SSR Markers

In this study, SSR analysis was performed on a large number of putative clones of the main olive cultivars from two Italian regions, Sicily and Calabria, in order to study the genetic relatedness, and to detect any degree of genetic diversity, which can be used to unambiguously identify possible superior clones. These putative clones have been collected and observed in the last ten years, following an extensive investigation carried out in traditional olive growing areas, thanks to the reports of farmers, millers, technician, growers and nurseries. The set of microsatellite (SSR) markers used allowed the detection of the genetic diversity, resulting from somatic mutation, indicating the pre…

Relationship between tree water status and physiology, yield, and fruit quality in the table olive (Olea europaea sativa L.) cultivar ‘Nocellara del Belice’

Although the olive (Olea europaea sativa l.) is considered a xerophytic species, long periods of water stress and high temperatures during summer months can greatly affect plant physiology and productivity. In recent years, the use of plant-based water status indicators have become popular in the study of plant-water relationships and in the design of irrigation programs, particularly midday stem water potential (ψstem). The current trend in the irrigation of olive trees is in the development of Deficit Irrigation (DI) systems whereby the water is applied at a rate which is lower than evapotranspiration needs, resulting in only very small reductions in yield. Rather than working towards min…

Physiological and Structural Responses to Prolonged Water Deficit in Young Trees of Two Olive Cultivars

This study aimed to characterize the physiological and structural responses of potted one-year-old olive trees belonging to two olive cultivars—‘Nocellara del Belice’ and ‘Cerasuola’—exposed to prolonged drought under greenhouse conditions. Two irrigation treatments based on evapotranspiration (ET) were imposed for 69 days, i.e., well-watered (WW, 100% ET) and drought-stressed (DS, 10–30% ET). Leaf stomatal conductance (gs), stem water potential (Ψstem), transpiration (E), photosynthetic capacity (Amax), water use efficiency (WUE), stem (Kstem) and root (Kroot) hydraulic conductance, trunk diameter variations (TDV), and leaf patch attenuated pre…

Genetic Characterization of Tunisian Olive Table Cultivars (Olea europaea L.): Inventory Based on Microsatellite Analysis

Olive (Olea europaea L.) is an ancient crop which spread from the Middle East towards the westem Mediterranean region. In addition lo its agronomical and economical importance, the olive industry has a great social and cultural interest as part of our heritage. In order to characterize and to study the genetic relationship among cultivars, five polymorphic microsatellite loci were used in this study and were generated a total of 56 polymorphic alleles with an average of 11 alleles by locus. For all genotypes, the highest number of polymorphic alleles was obtained by the locus UD0043 and GAPU 103. The polymorphism index content ranged from 0.836 for the locus ssrOeUADCA-04 and 0.919 for the …

Identification of self(in)compatibility genotypes and microsatellite marker based fingerprinting of traditional italian sweet cherry accessions

Italy is one of the main European sweet cherry producers and it has a rich germplasm, including many minor local varieties that have not been well studied or used in breeding programmes. Sweet cherry is self-incompatible, with few exceptions; its incompatibility is controlled by a multi-allelic S locus, which is gametophytically expressed. The knowledge of S-alleles and cross-incompatibility groups of sweet cherry genotypes and cultivars is important for growers and breeders. In this work we analysed 48 traditional sweet cherry varieties and cultivars, mainly from Calabria and Emilia Romagna regions, together with eight Sicilian cultivars and the standard set of reference genotypes proposed…

Evoluzione tecnica dei sistemi d'impianto nella peschicoltura degli ambienti a clima tipicamente mediterraneo

In peach industry, due to the increasing cost of the land, energy and salaries, in the last thirty years have been developed horticultural strategies to increase the productivity of the orchards and to reduce the employment of hand workers. In areas in which large part of the days are brilliant, clean sky, with high levels of light intensity, and relative humidity is low, as those with a Mediterranean climate, to reach the above mentioned goal have been developed planting systems based on high tree densities and new tree shapes. In Southern Italy, technicians have been particularly active in performing new tree canopy architectures and growers showed to be very sensitive to these innovation…

Transcriptomic Analysis of the Pistacia vera (L.) Fruits Enable the Identification of Genes and Hormone-Related Gene Linked to Inflorescence Bud Abscission

Pistacia vera (L.) is an alternate bearing species. The tree produces axillary inflorescence buds every year. Still, they abscise in “ON” overloaded shoots, causing a limited production in the following “OFF” year, causing a significant and unfavorable production fluctuation. In this work, we carried out de novo discovery and transcriptomic analysis in fruits of “ON” and “OFF” shoots of the cultivar Bianca. We also investigated whether the fruit signaling pathway and hormone biosynthesis directly or indirectly linked to the premature fall of the inflorescence buds causing alternate bearing. We identified 1536 differentially expressed genes (DE…

Effect of rootstock on growth, yield and fruit characteristics in cv 'Bianca' pistachio (Pistacia vera L.) trees

This paper, following preliminary field evaluation trials started in 1993, reports a study on the effect of eight different in vitro-propagated clonal rootstocks (P. atlantica and P. integerrima) and one seedling rootstock (P. terebinthus) on the vegetative and productive behaviour of pistachio cultivar 'Bianca'. The trees, budded in 1991, were grown using standard cultural practices for dry-land farming in a sandy clay loam soil, located inland in Sicily. On average, clones of P. integerrima (I-6 and I-2) were the most vigorous rootstocks. Clones of P. atlantica had intermediate vigour. Rootstock significantly affect yield but not fruit weight, kernel to nut ratio, splitting and blanking p…

VALUTAZIONE QUALITATIVA SU 3 CULTIVAR DI PISTACCHIO DI DIVERSA ORIGINE GEOGRAFICA

Genetic Diversity of Major Olive Varieties from Southern Tunisia

Considering the importance of olive-growing in Tunisia, microsatellite (SSR) analysis was used to study the genetic variation among twenty olive accessions from southern Tunisia. This set of olive microsatellites showed potential utility for genetic studies and it could contribute to the development of strategies for Tunisian germplasm conservation and breeding. Unweighted pair group method cluster analysis was performed and cultivars separated in three main groups. Five polymorphic simple sequence repeats (SSR) loci were employed and they revealed 38 alleles with a mean number of 7.6 alleles per locus. Genetic variability was wide as indicated by high values of both observed heterozygosity…

In this experiment carried out in Sicily (37.35N 12.58E), fruit growth was studied in relation to thermal time accumulated from bloom to fruit harvest for peach cultivars whose fruit development period ranges from 76 to 170 days. Thermal time was calculated in terms of GDH (base temperature 6.2-10 °C, optimum temperature 23.3-24.5 °C and critical temperature 33.7-39.4 °C) by the use of non-linear models. Climatic and phenological data (bloom and harvest dates) were considered for a minimum of four to a maximum of six years. Taking into account the whole FDP, the accuracy of the GDH model in predicting harvest time ranged from 0.6 day, in the early ripening peach cultivar Anita, to 6.4 days …

A Cultivar-Sensitive Approach for the Continuous Monitoring of Olive (Olea europaea L.) Tree Water Status by Fruit and Leaf Sensing

Sustainable irrigation is crucial to reduce water use and management costs in modern orchard systems. Continuous plant-based sensing is an innovative approach for the continuous monitoring of plant water status. Olive (Olea europaea L.) genotypes can respond to drought using different leaf and fruit physiological and morphological mechanisms. This study aimed to identify whether fruit and leaf water dynamics of two different olive cultivars were differently affected by water deficit and their response to changes of midday stem water potential (Ψstem), the most common indicator of plant water status. Plant water status indicators such as leaf stomatal conductance (gs) and Ψstem were measured…
