Nmr Study

Changes in metabolites (organic acids, sugars and amino acids) and subcellular pH were studied during fruit development of cherry tomato (Lycopersicon esculentum Mill. var. cerasiformae). Fructose and glucose were the major sugars, whereas citrate and malate the two major organic acids. At different stages of fruit development, vacuolar and cytoplasmic pH changes were followed by in vivo 13C and 31P NMR spectroscopy. Fruit compartments had a cytoplasmic pH around 7.1 as early as the cell-divi-sion and -expansion stages. The vacuolar pH measured by in vivo 13C NMR spectroscopy decreased from 4.5 to 3.6. Concomitantly, strong accumulation of γ-aminobutyric acid (GABA) was observed during the first 15 days after anthesis and glutamate decarboxylase (GAD) activity increased 10-fold during the first 8 days of development. The relationships between organic acid biosynthesis and storage, GABA produc-tion, and subcellular pH changes during development of cherry tomato fruit are discussed.

Lycopene Content

The cherry tomato fruit size depends on the growth of the pericarp which is parenchymal cells. The blue light stimulates the expansion of cotyledon cells, hypocotyl cells and leaf cells. In this study, the cherry tomato fruit was used as a material to investigate the effects of the blue light on the pericarp cells growth in fruit growth stage and lycopene accumulation in fruit growth and ripening stage. After 7 days of the blue light (440, 450 or 460 nm) treatment, pericarp cells growth and physiological, biochemical changes of the pericarp cells of 7-day-old fruit pericarp piece in vitro were analyzed. The lycopene content and some organic compound contents of 42-day-old postharvest fruits treated by the blue light similarly in 7 days and 7, 21-day-old fruit wrapped with blue filter (440-510 nm filtered) in 7 days were measured. The results showed that the 450 nm wavelength blue light the increased pericarp thickness of 7-day-old fruits through the increasement of the pericarp cell diameter. The 460 nm wavelength blue light the increased lycopene content of 42-day-old postharvest fruits. The blue filter treatment increased the sugar total content of 7- day-old fruits and increased the lycopene content of 21-day-old fruits.

The Impact

Cherry tomato “Atomic Grape” belongs to the Solanaceae family, an important species due to its economic value and high nutritional content. The impact on performance, weight, and nutritional profile of root, stem/branches, and leaves using the nutrient solution (NS), alone or combined with an organomineral fertilizer (F), whether granulated or in powder form was evaluated: NS, NS + F-granulated, and NS + F-powder. Best commercial fruits were obtained with NS + F-powder. Higher weights of both fresh and dry roots were obtained with NS + F-granulated and NS + F-powder. Mineral profile showed that the root builds up mostly nitrogen and silicon. Potassium was higher in stem/branches. Carbon, calcium, and sulfur were higher in the photosynthetic organ. NS increased the pH of the tomato juice by 9.81% and 10.90% compared to NS + F-granulated and NS + F-powder treatments. The organomineral fertilizer provides greater benefits due to its long-lasting effect on the soil and cherry tomato plant. In this experiment, we conclude that the combination of NS + F-powder obtained the best marketable fruits. It must be taken into consideration the greatest demand for nutrients in tomato given to developing organs such as leaves, flowers, and fruits. The leaves should be used for nutritional diagnosis, to confirm symptoms of deficiency or optimal nutritional ranges, which is of utmost importance for agronomists, growers, horticulturists, and physiologists.
