Abstract:

The influence of root colonization by arbuscular mycorrhizal (AM) fungus Funelliformis mosseae, on fruit quality, production and environmental sustainability were evaluated in field-tomato plants grown exposed to P-limited soil 5 μg g-1 soil (basal-soil) with nitrate fertilization (50 μg g-1 soil), after greenhouse germination and fungus colonization. After 60 days sowing (DAS), when the percentage of mycorrhizal root length (% RLC) raised at about 50%, the plants were transplanted in open field.
During the experiment, the mycorrhization has affected a lot of physiological aspects like vegetative and reproductive growth, improving them and ended the fruiting with a major fruit production that was 50% higher than not mycorrhizal (NM) plants. The ripening process of the fruits was also followed by testing sugars content and ß-Amylase activity in fruits of NM and mycorrhizal (M) plants fruits. At 140 DAS, in the harvesting fruits stage, fruits of M plants showed significantly higher mineral nutrient sugars and organic nitrogen compounds as amino acids and protein, compared to fruits from NM plants. In particular, GLU-GLN-ASP and ASN raised about 35% more than fruits from NM plants, improving nutritional aspect and flavor of the product. THR-ILEU-LEU-VAL and LYS, essential amino acids in man nutrition, increased around 25% more than fruits from NM plants, too. In this contest, lycopene, total carotenoids, ascorbic acid and glutathione (GS) and reduced form (GSH) were also tested in ripe fruits. The overall results suggest that tomato roots colonization by mycorrhizal fungus Funelliformis mosseae affects host plant nutritional status, modifying reproductive behavior, fruits production and nutritional quality.

Abstract:

In recent years chemical pesticides are being replaced by environmentally friendly and universal means of plant protection that are able to exert a complex effect on the plant (stimulate growth and development, improve metabolic processes, develop resistance to pathogens, etc.). The effect of new synthetic growth regulators of the 1,2,3-triazolo[5,1-b][1,3,4]thiadiazine class and trade phytohormones (6-BAP, GA and TDZ) on the growth processes, growth energy and vitality of tomato seeds, as well as morphological parameters of seedlings was researched in this article. It was revealed that the effect of synthesized compounds on seed vigor and viability of seedlings are superior to commercial phytohormones. In the early stages of germination the seed vigor of tomato seeds treated with the compounds TT1-TT5 were superior to one in treatments with phytohormones and in control experiment. As a result of the experiment, the most viable seedlings were formed into the treatments TT1, TT2 and TT3 (in all studied concentrations). Tomato seedlings treated with 6-BAP and GA at a concentration of 5 mg L-1 produced the worst results.
