“…In the same way, Khah et al (2006) reported nonsignificant differences in fruit firmness between grafted and nongrafted plants using 'Heman' and 'Primavera' as rootstocks and 'Big Red' as a scion. With regard to TSS content, there is no consensus on the effect of grafting on this variable; some studies have reported a negative effect on this trait (Khah et al, 2006;Turkmen et al, 2010), which may be a disadvantage for the rootstocks used in those works due to that TSS content is one of the most important characteristics for fruit flavor (Saltveit, 2005). In the present study, none of the Mexican native tomato rootstocks reduced the TSS content when 'El Cid' was used as scion, which represents an advantage over the commercial rootstocks ('Maxifort' and 'Multifort'), which had values of 3.2 and 3.1 °Brix, respectively, being a reduction of 14% and 16%, in the same order, compared to ungrafted plants.…”

these traits. The accessions LOR-22, LOR-77, LOR-81, LOR-84, LOR-95 and LOR-100 with the hybrid 'El Cid', and LOR-81, LOR-84 and LOR-100 with the hybrid 'Sun 7705', increased significantly yield by 19% and 22%, respectively, compared to ungrafted control. Moreover, characteristics related to fruit quality were preserved with grafting. The best combination scion/rootstock ('Cid'/100) yielded 30% higher than hybrid 'El Cid' without grafting and 16% higher than the commercial rootstock 'Multifort'. This allowed identifying genotypes of Mexican native tomatoes with great potential to be used as rootstocks or as source of germplasm for rootstock development.

“…Sweetness of tomato fruit was correlated not only with sucrose equivalents and pH but also with the volatiles including cis-3-hexenal, trans-2-hexenal, cis-3-hexanol, geranyl-acetone, 2-methylbutanol, 3-methylbutanol trans-2-heptenal, 6-methyl-5-hepten-2-one and 1-nitro-2-phenylethane. Likewise, sourness was correlated with soluble solids and pH along with the volatiles including acetaldehyde, acetone, 2-isobutylthiazole, geranyl-acetone, beta-ionone, hexanal and ethanol (Saltveit 2005).…”

Concentrations of different gases and volatiles present or produced inside a fruit are determined by the permeability of the fruit tissue to these compounds. Primarily, surface morphology and anatomical features of a given fruit determine the degree of permeance across the fruit. Species and varietal variability in surface characteristics and anatomical features therefore influence not only the diffusibility of gases and volatiles across the fruits but also the activity and response of various metabolic and physiological reactions/processes regulated by these compounds. Besides the well-known role of ethylene, gases and volatiles; O 2 , CO 2 , ethanol, acetaldehyde, water vapours, methyl salicylate, methyl jasmonate and nitric oxide (NO) have the potential to regulate the process of ripening individually and also in various interactive ways. Differences in the prevailing internal atmosphere of the fruits may therefore be considered as one of the causes behind the existing varietal variability of fruits in terms of rate of ripening, qualitative changes, firmness, shelf-life, ideal storage requirement, extent of tolerance towards reduced O 2 and/or elevated CO 2 , transpirational loss and susceptibility to various physiological disorders. In this way, internal atmosphere of a fruit (in terms of different gases and volatiles) plays a critical regulatory role in the process of fruit ripening. So, better and holistic understanding of this internal atmosphere along with its exact regulatory role on various aspects of fruit ripening will facilitate the development of more meaningful, refined and effective approaches in postharvest management of fruits. Its applicability, specially for the climacteric fruits, at various stages of the supply chain from growers to consumers would assist in reducing postharvest losses not only in quantity but also in quality.

“…It decomposes to ethylene, with the rate of decomposition depending on pH, temperature, concentration, and the degree of penetration of the tomato tissue (Saltveit, 2005a). When the fruits reach the breaker stage, internally synthesized ethylene sustains its own synthesis and stimulates ripening, even when the external concentration of ethylene has dropped to zero.…”

Ethephon is used to accelerate fruit ripening on plantations with well-developed plants which have formed a large quantity of fruits. The aim of the study was to determine the effect of ethephon on the chemical composition of the fruits of seven cultivars of processing tomato ('Rumba', 'Hubal', 'Sokal' F 1 , 'Mieszko' F 1 , 'Polset' F 1 , 'Hysioux' F 1 and 'AF1120' F 1 ), applied to the plants when most of the fruits had reached the mature-green stage. The study was conducted during three consecutive years, characterized by different weather conditions. Meteorological elements, i.e. air temperature and precipitation totals, were monitored in the experimental station in Mydlniki, near Krakow, Poland. Ethephon was found to have a beneficial effect on the content of extract and soluble sugars of the harvested tomatoes and on their acidity. Dry matter and lycopene levels were not dependent on the use of this compound, while the ascorbic acid content was reduced by the procedure. The chemical composition of the tomato fruits differed significantly in consecutive years of the study, which confirmed the weather impact on fruit quality and on the varied responses of different cultivars to use of ethephon. The tested cultivars were also compared in terms of their suitability for processing. The 'Hubal' cultivar had the highest content of dry matter, extract, soluble sugars of all the cultivars tested. The highest level of lycopene was noted for the tomatoes of the 'Rumba' and 'Sokal' F 1 cultivar, ascorbic acid of the 'Rumba' and the highest acidity for 'AF 1120' F 1 .
