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…

Investigating the cryopreservation of nodal explants of Lithodora rosmarinifolia (Ten.) Johnst., a rare, endemic Mediterranean species

2012

In this study, we investigated the possibility of using the droplet-vitrification technique for cryopreserving nodal segments of in vitro plantlets of the endangered plant species Lithodora rosmarinifolia. Among the three vitrification solutions tested, only solutions B1, containing (w/v) 50 % glycerol and 50 % sucrose, and B3, containing 40 % glycerol and 40 % sucrose, were able to induce cryotolerance in nodal explants, resulting in intermediate survival and recovery after cryopreservation. A three-step vitrification protocol, including an additional dehydration treatment with half-strength vitrification solution for 30 min before the treatment with full-strength vitrification solution, d…

Cryopreservation of Limonium serotinum apical meristems from in vitro plantlets using droplet-vitrification

2011

Abstract In this study in vitro shoot tips of a Sicilian genotype of Limonium serotinum were successfully cryopreserved using the droplet-vitrification technique. Growth recovery of cryopreserved shoot tips was possible only when samples were pretreated for 16 h in liquid medium with 0.3 M sucrose, then for 5 h in liquid medium with 0.7 M sucrose before performing the cryopreservation protocol. Optimal conditions included treatment for 20 min in a loading solution containing 1.9 M glycerol + 0.5 M sucrose, treatment with vitrification solution B5 (glycerol 40.0%, sucrose 40.0%, w/v) for 60 and 90 min or vitrification solution A9 (glycerol 30.0%, dimethylsulfoxide 20.0%, ethylene glycol 20.0…

Valutazione di ecotipi siciliani di melone d'inverno coltivati in regime seccagno

2010

The increasing cultivation of hybrid melon cultivars has caused the loss of several Sicilian landraces characterized by a high level of diversity, tolerance to environmental stress, disease resistance, and high quality fruits. Although the majority of hybrid melon fields in the Sicilian countryside are nowadays irrigated, many farmers are still growing melon landraces without irrigation. In this trial, eight Sicilian landraces of winter melon (Cucumis melo L. var. inodorus Naud.) with yellow skin and three with white skin were compared with the commercial cultivar Helios. Plants were grown at a density of 2080 plants ha-1. without irrigation. ‘Locale di Ustica’ and ‘Giallo di Recattivo’ gav…

The influence of addition of Borago officinalis with antibacterial activity on the sensory quality of fresh pasta

2015

Abstract Borage (Borago officinalis L.) is a herbaceous plant of the Boraginaceae family cultivated throughout the world for several purposes, including food preparations, mainly beverages and salads. Some Italian recipes use borage as a food ingredient, in particular as condiment for pasta. The aqueous extract (AE) from borage leaves can act as biopreservative in foods due to its inhibition towards the main foodborne pathogen bacteria. Fresh pasta, due to the high content of water, is a food product with a limited shelf life. In order to test the suitability of borage to produce fresh pasta with a prolonged shelf life, borage AE was used in dried form as a raw material for the production o…

Un-rooted grafted cuttings for eggplant plug-transplant production and shipping: simulated transportation and healing requirements

2019

Vegetable grafting is one of the most effective eco-friendly techniques to overcome pests and soilborne diseases in modern cropping systems of fruiting vegetables. Due to the increased farmers’ preference for grafted seedlings of high quality and better performance, the use of vegetable grafted plants is rapidly spreading and expanding over the world and intensive researches on new commercial production systems are under way. However, in many areas of the world, due to the high cost of skilled manpower, the use of grafted plug plants is still limited causing a relatively slow development of the grafting nursery industry. The aim of this work was to evaluate a possible use of un-rooted graft…
