LE SPECIE DELLA FLORA VASCOLARE SICILIANA INCLUSE NELLE NORMATIVE INTERNAZIONALI
2012
Species of sicilian vascular flora included in the international laws. The present paper aims to divulgate the knowledge of the Sicilian flora protected at international level and includes a check-list of the Sicilian vascular flora recorded in international normatives on the protection of nature and biodiversity. For each normative general information is given together with a reference list to further deepen the contents, the aims and the present implementation in Italy.
Effect of Nitrogen Fertilization on the Quality of Swiss Chard at Harvest and during Storage as Minimally Processed Produce
2014
The effects of different levels of nitrogen fertilization (0-50-100-150-200 kg ha-1), minimal processing and cold storage (14 days at 4°C) on yield and quality of fresh-cut Swiss Chard (Beta vulgaris L. var. cicla L.) were evaluated. Increasing the level of nitrogen fertilization over 100 kg N ha-1, plants had a higher fresh weight, reduced their dry matter content and resulted taller and leafier. Total and marketable yield increased linearly as increasing nitrogen level. Both nitrate and ascorbic acid content at harvest increased as increasing nitrogen supply. Nitrogen fertilization negatively affected the yield of minimal processing. No effect on appearance and quality loss during cold st…

Prove preliminari per la valorizzazione della borragine (Borrago officinalis L.) come prodotto minimamente processato
2012
La borragine (Borago officinalis L.) è una pianta erbacea annuale tomentosa della famiglia Boraginaceae originaria dell'Europa e del Nord Africa, ampiamente diffusa in molti paesi mediterranei. Questa pianta è coltivata in tutto il mondo ed è usata per scopi medicinali nonché per la preparazione di bevande e per essere consumata cruda o cotta. La coltivazione della borragine è principalmente orientata alla produzione di seme, mentre la coltura da ortaggio è molto limitata e spesso si ricorre alla raccolta delle piante spontanee per soddisfare le richieste di mercato. Al fine di valorizzare il potenziale orticolo di questa specie, la presente ricerca ha lo scopo di valutare la possibilità di…
Effects of packaging on shelf-life and quality of minimally processed fennel
2018
Fennel is not a widespread product among minimally processed vegetables, due to the fast deterioration mainly caused by browning of the cut surfaces, even during cold storage. In order to extend the shelf-life of fresh-cut fennel, the influence of different packaging techniques was studied. Sliced fennel, dipped in a citric acid solution (0.5%), was placed in polystyrene trays, sealed with PE film or vacuum packaged in PE bags and stored up to 14 days at 4°C. During this period the weight loss, soluble solid content, pH, color and firmness were evaluated. Minimally processed fennel packed in sealed trays and cold-stored at 4°C, extended its shelf-life to 14 days maintaining acceptable quali…
Assessing Hydrus-2D model to investigate the effects of different on-farm irrigation strategies on potato crop under subsurface drip irrigation
2019
The objective of this paper was to assess the performance of Hydrus-2D model to simulate the effects of different on-farm irrigation strategies applied on potato crop. The ability of the model to simulate the stress coefficient (Ks), obtained as the ratio between actual and maximum transpiration, and to define the productive function of potato crop under the semi-arid conditions of central Tunisia were also evaluated. Experiments were carried out on potato crop under full (FI) and deficit irrigation (DI) and two different water qualities supplied by means of a subsurface drip irrigation system. Results evidenced that the model, despite some discrepancies locally observed, can fairly accurat…
Effects of Foliar Application of Gibberellic Acid on the Salt Tolerance of Tomato and Sweet Pepper Transplants
2020
Seed germination and early seedling growth are the plant growth stages most sensitive to salt stress. Thus, the availability of poor-quality brackish water can be a big limiting factor for the nursery vegetable industry. The exogenous supplementation of gibberellic acid (GA3) may promote growth and vigor and counterbalance salt stress in mature plants. This study aimed to test exogenous supplementation through foliar spray of 10&minus
EFFECT OF HOT AIR TREATMENT ON MINIMALLY PROCESSED CAULIFLOWER
2013
The request of minimally processed vegetable is continuously increasing, and there is a growing interest for new fresh cut products. Cauliflower, as other cabbages, is highly appreciated for its nutritional value due to the good content of vitamins, antioxidants and anti-carcinogenic compounds. It is suitable to be used as a minimally processed vegetable, but harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The aim of the present work was to investigate the effect of hot air treatment and cold storage on minimally processed green cauliflower. Fresh-cut cauliflower florets put in sealed PE bags were treated at 48…

Use of Unrooted Grafted Vegetable Cuttings: I. Effects of Healing Duration and Transportation Temperature
2013
ogy to overcome soil-borne diseases and pests and to add extra vigor to the plants under various environmental stress conditions. In order to advance the use of grafting in U.S. vegetable production in open fields, key issues to address include 1) increasing the propagation capacity to meet the expected large number of seedlings necessary to supply the demands of typically large farms and 2) reducing production costs. Traditionally, vegetable grafting is a labor-intensive process involving much training and logistics. However, the seasonal nature of nursery operations due to the limitation of transportation of the grafted seedlings is problematic when nurseries are interested in introducing…
