“…At least two strategies can be envisioned to cope with this problem. First, Zn hyperaccumulators could be grown in controlled growth media as is widespread practice for salad plants (Tomasi et al 2015). A disadvantage is the infrastructure requirement of such approaches.…”

Background Zn hyperaccumulating plants reach Zn concentrations in their leaves that are several hundredfold higher than the target values set for Zn-biofortified crops. Scope This extreme trait is relevant for Zn biofortification in various ways that are being discussed based on what is known about Zn hyperaccumulating plants.Conclusions First, Zn hyperaccumulation is the result of changes in metal homeostasis networks shared by all higher plants. It is not strictly dependent on high Zn levels in the soil. Thus, mechanistic insights gained from the study of Zn hyperaccumulators can support the breeding and engineering of Zn-biofortified crops. Second, certain plant families, the Brassicaceae in particular, appear to be genetically predispositioned to evolve enhanced Zn accumulation, suggesting the existence of intermediate species with elevated Zn concentrations in their leaves below the hyperaccumulation threshold or the potential to breed for such plants. This calls for extended screening especially among potential vegetable crops, ideally guided by knowledge about the at least partially convergent evolution of Zn hyperaccumulation. Third, the introduction of leafy vegetables with high Zn concentrations or even of Zn hyperaccumulator leaves into diets may represent a valid complementary biofortification approach.

“…Considering the nutrient management options that soilless culture systems provide, plants nutrient requirements are easier to fulfill, resulting in products of high quality, less nutrients deficiency symptoms that affect visual appearance and better consumers' acceptance. Moreover, the potential of custom formulations of nutrient solutions can be a useful means towards micronutrients' biofortification of the final product, as well as the addition of non-essential minerals (Tomasi et al, 2015). Coronel et al (2009) reported that chlorophyll content and nitrate reductase activity was greater in lettuce plants grown hydroponically than in plants grown with traditional methods.…”

In recent years, there has been a growing trend towards cultivating leafy vegetables in hydroponic systems. Floating system is an alternative hydroponic system suitable for the production of baby vegetable products, ready-to eat salads and minimally processed leafy vegetables. However, the implementation of this system for the production of fully grown leafy vegetables is not sufficiently studied. The aim of the present study was to examine the potential of floating system as an alternative growing technique of lettuce and rocket plants, as well as the effect of nitrogen (N) application rate (three treatments 100, 150 and 200 mg L -1 of N) on plant physiology, quality and yield during three growing periods. The results showed that increasing the N application rate resulted in an increase of fresh weight of the aerial parts of both lettuce and rocket, while total yield ranged between 12.0 to 41.9 and 8.0 to 30.2 kg m -2 of fresh leaves, for lettuce and rocket, respectively. In addition, increasing the nitrogen rate resulted in higher number of leaves for lettuce and rocket, as well as in a significant increase in the rate of photosynthesis. A similar increase was observed in nitrate, K, Mg and Mn content in the leaves, without however exceeding the permissible limits for nitrates in any case. In conclusion, the use of floating raft technique for lettuce and rocket cultivation in order to produce not only seedlings production or baby products, but also fully grown plants of high quality is highly recommended.

“…Conflicting evidence exists concerning the effects of SCS on the visual quality, tissue browning and the phytochemical compound content in horticultural products, such as in strawberries, melons, tomatoes, peppers, eggplants, cucumbers, beans, celery, parsley, dill, basil, radish, lettuce, rocket, cress and spinach (Degl'Innocenti et al 2005;Fallovo et al 2009a, b;Fontana and Nicola 2009;Gruda 2009;Nicola et al 2002Nicola et al , 2010Selma et al 2012;Tomasi et al 2015;Zhan et al 2009). SCS allow raw material with reduced agronomic and chemical residues, undesirable compounds and microbiological contamination to be obtained at harvest (Olympios 1999;Tognoni et al 2005;Zanin et al 2009).…”

“…Iron absorption is affected by a pH > 7.0, and the presence of manganese, with which it is in competition for root absorption (Tomasi et al 2015). Iron can be supplied as iron(II) phosphate, iron(III) phosphate, iron(II) sulphate, iron(III) sulphate or iron chelate.…”

The book series Advances in Olericulture provides a state-of-the-art account of research in olericulture, the applied life science of production and utilization of vegetable crops. The series focuses on various aspects of vegetable science and technology covering primarily but not exclusively species where the vegetative organ is the economically important component. The series of books spans current topics from sustainable fertilization to organic production; from open field cultivation to advanced soilless growing techniques; from vegetable seed and seedling physiology to vegetable quality and safety; from environmental stresses to phyllosphere communities interaction with vegetables; from postharvest biology and technology to minimally processing of vegetables. The series is designed to present the most advanced scientific information available linking basic and applied research for serving olericulturists, research workers, teachers and advanced students.More information about this series at
