The effect of explant cut and cytokinin type on micropropagation of fig (Ficus carica L.) 'Brown Turkey'
2017
This study was conducted to micropropagate 'Brown Turkey' fig, one of the most popular cultivars in California, USA for fresh and dried uses. Nodal segments cut lengthwise or not were cultured on Woody Plant Medium containing 0.3, 1.0 or 3.0 μM of N6 benzyladenine (BA) or kinetin in a 3 (concentrations) × 2 (cytokinins) × 2 (explant types) factorial experiment. 60% of explants became contaminated with various microbes when the standard protocol of washing shoots for 3 h under running tap water. Microbial contamination was nearly eliminated when the running water rinse and the use of an ascorbic acid dip were eliminated. Phenolic exudation was not a problem. Shoots grew longer with more leav…
Early bearing and vegetative growth of 153 Sicilian olive accessions
2018
In 2014, an olive germplasm collection was established in south-western Sicily, Italy. The collection included 153 Sicilian accessions and 3 international varieties (reference), each with 7 trees, spaced at 5×2 m and trained to hedgerow system. The aim of the trial was to study early growth and yield responses of the accessions to super-high planting density (SHD). Trunk cross sectional area, tree height, pruning weights, shoot positioning, blooming and fruit yield (kg tree-1) were measured in 2015 and 2016. Based on trunk growth and amount of prunings, the 153 accessions were separated into four categories of vigor as it follows: very high vigor (6 accessions), high vigor (13), medium vigo…
Horticultural performance of 23 Sicilian olive genotypes in hedgerow systems: Vegetative growth, productive potential and oil quality
2017
Abstract The super high density (SHD) model is a new olive growing system characterized by earlier and higher yields, fully mechanized harvesting and reduced orchard management costs. Until recently all commercial SHD orchards were planted primarily with three varieties: ‘Arbequina’, ‘Arbosana’ and ‘Koroneiki’. To increase variety diversity, broaden available olive oil chemical and organoleptic profiles, and olive oils for marketing, minor local varieties should be evaluated for adaptability to the SHD system. This study compares multiple Sicilian native genotypes to the three current cultivars ‘Arbequina’, ‘Arbosana’ and ‘Koroneiki’. The cumulative fruit and oil production, trunk-cross sec…
New selections of Prunus persica for low chill Mediterranean climate areas
2016
In the late 1990s, CREA and the University of Palermo initiated a peach-breeding program in order to select new genotypes suitable for the fruit growing areas of southern Italy. These regions are generally characterized by short, mild winters and long, hot, dry summers. International cultivars grown in continental environments often have problems related to climatic limitations, such as the failure to satisfy the winter chill requirements. About 40 different peach and nectarine cultivars with different fruit characteristics (size, skin over colour, flesh firmness, sugar content, titratable acidity, absence of split-pit) were used as parents in a breeding program by CREA. The best selections…
Genetic diversity of early ripening breba accessions (Ficus caricaL.) found in the “Pomona” Apulian collection
2017
In order to study fig (Ficus carica L.) biodiversity in Southern Italy, a study was performed in a private Apulian collection, "I Giardini di Pomona", in which 350 different native and international cultivars were recovered in the last 15 years. This collection is located in middle part of Apulia region inside an area of great charm called "Valle D'Itria". In the region, fig is an important edible fruit tree species and it has been used for fresh fruit production, for centuries. Moreover, fig is considered as an important element of natural landscape and as significant cultural heritage. In this study, the Apulian breba cultivars, characterized by interesting agronomic traits, such as early…
