Abstract:
... The study was carried out in an olive grove located along the hills of northern Sicily where soil had been managed for decades by chemical weeding. Starting in 2008, one portion of the grove was left non-weeded, and the permanent grass cover was managed by mowing 2-3 times per year in winter and spring. In 2011, 2012 and 2013, yield, average drupe weight, percentage of drupe black color (veraison) ...

Abstract:
... To understand the relations between water availability existing in semi-arid conditions of central Tunisia and yield components of olive trees, a field experiment was carried out to study the behavior of local and foreign cultivars under two irrigation regimes (small water supply 10% ETc which was closed to rain-fed condition and full irrigated 100% ETc). The trial was carried out over a 2-year pe ...

Olea europaea; branches; breeding programs; canopy; crossing; cultivars; early development; flowering; fruiting; juveniles; olive oil; seedlings; tree breeding; trees; vigor; Tunisia
Abstract:
... The prolonged length of the juvenile period is considered to be the main obstacle for any olive tree breeding program. The knowledge of the moment when the plant starts flowering is important for the breeding program. In Tunisia, a breeding program by controlled crosses of the olive oil cultivar 'Chemlali' was developed and of which some seedling plants began fruiting. Series of standard morpholog ...

Olea europaea; alternate bearing; branches; canopy; cultivars; flowers; mature plants; olives; reproductive behavior; shoots; tree yields; trees; vegetative growth
Abstract:
... The olive tree is a well-known alternate-bearing species. Because of competition between vegetative growth and fruit development processes, a high yield year is generally followed by a low yield year. In order to elucidate this phenomenon, the patterns of vegetative growth and the reproductive behavior were studied on three fruit bearing trees (on trees) and three non-bearing trees (off trees) of ...

5. Tree crown parameters assessment using 3D photo reconstruction as a tool for selection in olive breeding programs

Olea europaea; breeding programs; canopy; cost effectiveness; cropping systems; crows; cultivars; genotype; models; olives; plant architecture; plantations; planting; remote sensing; tree crown; trees
Abstract:
... In olive, both discontinuous canopy (open vase configuration) and continuous canopy (hedgerow) systems are used in commercial planting. Reliable and cost effective plant architecture characterization is necessary to test the suitability of cultivars to specific growing systems, particularly in olive breeding programs where a large number of genotypes must be evaluated. In this work, the performanc ...

Abstract:
... Olive (Olea europaea L.) plants have been originated from the Mediterranean sea and has been grown since very old times. Olive (Olea europaea L.) cultivars have been grown and multiplied by hardwood cuttings in conventional method. Such techniques are time taking and are labor consuming. This traditional technique is less efficient and not that effective. An efficient and reproducible protocol for ...
