“…The negative relation between yield and shelf life can be associated to an increased fruit water content (lower SSC) which potentially can reduce shelf life [27], among other factors [21]. Few reports have been published regarding preharvest factors that affect postharvest shelf-life in tomato [3,6,32,[80][81][82]; our results confirm the difficulty of identifying single factors affecting postharvest storage, a trait affected by complex genotype x environment x management interactions. Studies of long shelf life varieties could play a key role in deciphering these effects.…”

The individual effects of biotic and abiotic factors on tomatoes have been widely reported. However, under commercial conditions, multiple interactions between factors occur, masking or even changing the direction of their effects in some cases. Here we report a comprehensive analysis of preharvest factors affecting yield, quality (soluble solids content, fruit color, and firmness), and shelf-life of long-shelf-life Mediterranean varieties of tomatoes. We studied five long-shelf-life genotypes under 16 growing environments, including tunnel and open-air systems and suboptimal to excessive fertigation (22–142% crop evapotranspiration). The results enabled us to classify traits into three groups according to the importance of the contributions of different types of factors: mainly genotype (ripening earliness and firmness), genotype plus environment (yield, fruit weight, water-use efficiency (WUE)), or genotype plus environment plus the interaction between genotype and environment (cracking, soluble solids content, and shelf-life). Under similar management practices, open-air conditions optimized yields, and high fertigation doses improved yield and marketability (firmness), but reduced quality (redness and soluble solids content). WUE was maximized under low-input cropping systems (comparable to traditional agrosystems), and the balance between WUE and yield was optimized when fertigation was adjusted to the requirements of the crop. Shelf-life was negatively correlated with high-yielding environments, and day–night amplitude in relative humidity was strongly correlated with the incidence of fruit cracking. The present study sheds light on the contributions of environment and management practices on tomato yield and quality, and provides a basis on which to select better management practices for the novel commercial group of European long-shelf-life tomato landraces.

“…In the Si treatments, 2 mM of K 2 SiO 3 was added in the nutrient solution while an equivalent concentration of potassium (K) was obtained in the control solution using K 2 SO 4 . With this expedient, control and Si-enriched nutrient solution had the same K concentration and K:Ca:Mg ratio as suggested by other authors (Costan et al, 2020). Either K 2 SiO 3 or K 2 SO 4 were added to the following basic nutritive recipe: N-NO 3 6.4 mmol L −1 , N-NH 4 0.8 mmol L −1 , P-PO 4 0.8 mmol L −1 , K 4 mmol L −1 , Ca 1.8 mmol L −1 , Mg 0.4 mmol L −1 , Na 0.5 mmol L −1 , S-SO 4 1.03 mmol L −1 , Cl 0.5…”

Edible flowers are becoming popular as a nutraceutical and functional food that can contribute to human nutrition with high antioxidant molecules and mineral elements. While comparative studies between different flower species have been performed, less is known about the best agronomical practices to increase yield and nutraceutical proprieties of blooms. Silicon stimulates plant resistance against stress and promotes plant growth while non-thermal plasma (NTP) technology has been applied for the disinfection and decontamination of water, as well as for increasing plant production and quality. The application of silicon and NTP technology through nutrient solution and spraying was investigated in edible flowers given that the combination of these treatments may play a role in promoting their nutritional and nutraceutical proprieties. The treatments were applied on two varieties of Begonia cucullata Willd. (white and red flowers) to explore their effects on different flower pigmentations. Plants with red flowers showed higher nutraceutical proprieties than the white ones but yielded a lower flower number. While the NTP treatment did not improve flower yield and quality, the silicon treatment increased anthocyanins and dry weight percentage in red flowers. NTP treatment increased zinc concentration, while it decreased potassium, magnesium, and manganese, and increased silicon concentration in white flowers. The combination of silicon and NTP showed negative effects on some nutraceutical proprieties of red flowers thus highlighting that the two treatments cannot be combined in edible flower production. In conclusion, the positive effect of silicon use in edible flower production has been demonstrated while the NTP technology showed contrasting results and its use should be explored in greater depth, including a consideration of its role in biotic attack prevention and reduced chemical input.

“…Although the beneficial role of Si in the alleviation of different abiotic stresses is well documented, 5,13,18,19 little is currently known regarding the relevance of Si in the physiology of plants subjected to toxic levels of NH 4 + . We hypothesized that NH 4 + toxicity in radish seedlings might be mitigated by the incorporation of Si into the nutrient solution used in hydroponic cultivation.…”

Physiological role of silicon in radish seedlings under ammonium toxicity

BACKGROUND: High concentrations of ammonium as the sole nitrogen source may result in physiological and nutritional disorders that can lead to reduced plant growth and toxicity. In this study, we hypothesized that ammonium toxicity in radish seedlings (Raphanus sativus L.) might be mitigated by the incorporation of silicon (Si) into applied nutrient solution. To examine this possibility, we conducted a hydroponic experiment to evaluate the effects of five concentrations of ammonium (1, 7.5, 15, 22.5, and 30 mmol L −1) on the photosynthesis, green color index, stomatal conductance, transpiration, instantaneous wateruse efficiency, and biomass production of radish in the absence and presence (2 mmol L −1) of Si. The experimental design was a randomized block design based on a 2 × 5 factorial scheme with four replicates. RESULTS: The highest concentration of applied ammonium (30 mmol L −1) was found to reduce the photosynthesis, transpiration and total dry biomass of radish seedlings, independent of the presence of Si in the nutrient solution. However, at lower ammonium concentrations, the application of Si counteracted these detrimental effects, and facilitated the production of seedlings with increased photosynthesis, greater instantaneous water-use efficiency, and higher total dry biomass compared with the untreated plants (without Si). Transpiration and stomatal conductance were affected to lesser extents by the presence of Si. CONCLUSION: These findings indicate that the addition of Si to nutrient solutions could provide an effective means of alleviating the unfavorable effects induced by ammonium toxicity at concentrations of less than 30 mmol L −1 .
