“…Tomato plants ( Lycopersicon esculentum [L] Mill cv Counter) of stem length up to 8 m were grown in rockwool in a glasshouse under semi‐commercial conditions ( van de Vooren, Welles & Hayman 1986). Fruit of all stages were harvested as required, taking only the first (most proximal) fruit from any truss.…”

The cessation of tomato fruit growth is thought to be induced by an increase in the activity of enzymes which rigidify cell walls in the fruit skin. Peroxidase could catalyse such wall-stiffening reactions, and marked rises in peroxidase activity were recently reported in skin cell walls towards fruit maturity. Peroxidase isoforms in the fruit are here analysed using native gel electrophoresis. New isoforms of apparent M r 44, 48 and 53 kDa are shown to appear in cell walls of the fruit skin at around the time of cessation of growth. It is inferred that these isozymes are present in the cell wall in vivo. Fruit from a range of nonripening mutants were also examined. Some of these do not soften or ripen for many weeks after achieving their final size. The new isozymes were found in skin cell walls of mature fruit in each of these mutants, as in the wild-type and commercial varieties. It is concluded that the lateappearing isozymes are not associated with fruit ripening or softening, and are probably not ethylene-induced. They may act to control fruit growth by cross-linking wall polymers within the fruit skin, thus mechanically stiffening the walls and terminating growth.

“…To ensure equality between HP units, on 25 July, one shoot per channel was removed, leaving 22 healthy shoots, with each tomato plant occupying an average area of 1.1 m 2 . The tomato plants were cultivated using a high wire system [25], with the supporting wire at a height of 4.20 m. The growth period after transplanting was 31 weeks. The tomato plant tips were cut nine weeks before the end of the experiment to prevent further elongation.…”

Aquaponics (AP) is a food production system that combines hydroponic (HP) crop production with recirculating aquaculture. Different types of hydroponic systems have been used for growing crops in aquaponics. However, very few studies have compared their suitability and efficiency in an aquaponic context. The study presented here compares tomato yield, morphological (external) and biochemical (internal) fruit quality, and overall tomato plant vitality from three different HP systems (nutrient film technique, drip irrigation system, and floating raft culture) and examines the distribution of nutrients in different parts of the tomato plant. Three replicate AP systems were set up, each incorporating the three different HP systems coupled with a separate recirculating aquaculture unit growing Nile tilapia. The results showed that the choice of the cultivation system had little influence on most of the above-mentioned properties. Tomato fruit mineral content was found to be in similar range for N, P, K, Ca, Mg, Fe, and Zn as reported in the literature. Yield and fruit quality were similar in all three systems. However, the drip irrigation system did perform slightly better. The slightly higher oxygen radical absorbance capacity (ORAC) of the fruits grown in AP in comparison to commercially produced and supermarket derived tomatoes might indicate a potential for producing fruits with higher health value for humans.

“…The initial density was 25 pots m −2 and parted to 14.5 pots m −2 six weeks after transplanting. A mineral solution derived from Van de Vooren et al (1986) with pH of 5.2-5.9 and conductivity of 2.4 mS cm −1 was delivered to plants through the Priva Inteígro "Nutrifix" dosing unit (De Lier, The Netherlands). The composition of nitrate-N, P and K in the nutrient solution was 6, 0.5 and 2.4 mmol L −1 , respectively while other macro elements (at the range of 0.6-1.4 mmol L −1 ) and trace elements (at the range of 0.5-8 mol L −1 ) were also included.…”
