Genetic variation of an Italian long shelf-life tomato (Solanum lycopersicon L.) collection by using SSR and morphological fruit traits

2014

The recovery of ancient germplasm in tomato (Solanum lycopersicon L.) has become necessary to limit the wide genetic erosion caused by the employment of modern cultivars. Among germplasm collections, long shelf-life landraces could represent an important source of biodiversity. The present study provides a first set of molecular and phenotypic data on long shelf-life (so called "da serbo" in southern Italy) tomato collection, mainly originated from Sicily together with some landraces from Campania and Apulia. The analysis of fruit traits showed a low intra-varietal variation, while exhibiting a quite higher inter-varietal variability. Overall, the cultivars have been classified in six fruit…

Evaluation of strawberry cultivars in soilless cultivation in Sicily

PLANTING DENSITY AND PRUNING METHOD AFFECT EGGPLANT SOILLESS CULTURE

2007

The aim of this research was to evaluate the effects of two planting densities (1.6 plants-m-2 or 2.5 plants-m-2) and two pruning methods (two or four stemmed plants) on eggplant cultivars Black Bell and Longo in soilless culture. The research was carried out in 2003-2004 in the Northern coast Sicily. Eggplant plug plants were transplanted in a heated glasshouse in polystyrene containers (80 cm in length, 25 cm in width, 20 cm in height) filled with coconut coir dust. The experimental design was a split-split plot. Fruit production from January to April increased significantly as planting density increased. Irrespectively of the cultivars, four stemmed plants gave higher yields than two ste…

Effects of plant type on two strawberry cultivars in Sicily

2014

In Sicily fresh plants have for years been replacing the once popular cold-stored ones. Good early cropping is the aim of all strawberry growers in the island’s Marsala district. The present trial tested the response of the new strawberry cultivars ‘Sabrosa’ and ‘Florida Fortuna’ using fresh plug and bare-root plants. ‘Florida Fortuna’ plug-plants turned out to be the most promising type as a cash crop in delivering extra early ripening.

EFFECTS OF PRE-PLANT SOIL TREATMENTS ON STRAWBERRY IN SICILY

2014

The 2005 ban by Italy of methyl bromide (MB) has resulted in significant crop management difficulties in pre-plant soil dis-infestation. We report two pre-plant soil treatment techniques and their effects on the performance of new cultivars and selections tolerant to the main root pathogens. The plants grown in soil treated with chloropicrin + 1,3 dichloropropene were the most productive. While neither treatment affected average berry weight, soluble solids content or titratable acidity, the treatment × cultivar interaction was significant and fruits from plants grown in treated soil were firmer than control s. Selection PA 260 and cultivar Florida Fortuna were the earliest, three selection…

Micropropagation ofAgeratum houstonianumby nodal segments

2017

Ageratum houstonianum is a bedding and flowering potted plant originated from Central America which is generally propagate by seed. In this report a preliminary in vitro technique for propagation of A. houstonianum was investigated. In vitro germinated seeds were used to establish aseptic shoot cultures of several clones. Seedling stem segments bearing 3-4 nodes were placed on Murashige and Skoog (MS) basal medium plus 20 g L-1 sucrose, 8.0 g L-1 Agar to induce axillary shoot development. Axillary shoots were subcultured into the same medium and nodal segments were sectioned and subcultured to increase the stock of shoot cultures. Shoot cultures of the selected clone AG14 were used to accom…

COLLARD GREEN (BRASSICA OLERACEA VAR. ACEPHALA) CULTIVATION IN SICILY

2013

Collard greens (Brassica oleracea var. acephala) are a group of plants cultivated for its thick, slightly bitter, edible leaves. As other Brassicaceae, have a good nutritional value as they are a good sources of vitamin C and soluble fiber, and contain various compounds with potent anticancer properties. In order to enhance collard cultivation in Sicily, different planting dates were tested. The research was carried out during 2009-2010 in the experimental field of SAgA Department – University of Palermo. Plants of a Sicilian local cultivar, with high vigor, good emission of side shoots, large and moderately curly leaves and long and strong petiole, were planted in three different periods: …

Microbiological investigation of Raphanus sativus L. grown hydroponically in nutrient solutions contaminated with spoilage and pathogenic bacteria

2012

Abstract The survival of eight undesired (spoilage/pathogenic) food related bacteria (Citrobacter freundii PSS60, Enterobacter spp. PSS11, Escherichia coli PSS2, Klebsiella oxytoca PSS82, Serratia grimesii PSS72, Pseudomonas putida PSS21, Stenotrophomonas maltophilia PSS52 and Listeria monocytogenes ATCC 19114T) was investigated in mineral nutrient solution (MNS) during the crop cycle of radishes (Raphanus sativus L.) cultivated in hydroponics in a greenhouse. MNSs were microbiologically analyzed weekly by plate count. The evolution of the pure cultures was also evaluated in sterile MNS in test tubes. The inoculated trials contained an initial total mesophilic count (TMC) ranging between 6.…

ARBUSCULAR MYCORRHIZAL INOCULATION AND SHADING ENHANCE CROP PERFORMANCE AND QUALITY OF GREENHOUSE Begonia semperflorens

2019

Mycorrhizal fungi are gaining interest in the floriculture sector due to the beneficial effects on a crop performance and ornamental quality. The aim of the current study was to assess the effect of inoculation with the arbuscular mycorrhizal (AM) fungi Rhizophagus irregularis on ornamental quality of Begonia × semperflorens-cultorum grown in two different protected cultivation systems: a shadehouse or glasshouse. The inoculated plants incurred a significant increase of plant height by 34.6%, lateral shoot length by 27.9%, number of lateral shoots by 41.2%, number of flowers per plant by 102.9%, flower diameter by 27.5%, and stems dry weight by 263.6%. High temperatures in the glasshouse ne…
