Abstract BACKGROUND: The agricultural production system and cultivation practices are critical factors in determining yield food nutritional quality. Controversy remains regarding whether or not organic foods have a advantage when compared with their conventionally produced counterparts. In this study the effect of conventional systems on yield, physicochemical properties four field tomato cultivars (Perfectpeel, Rio Grande, Hypeel 108 Firenze) was determined. system, different fertiliser...
This study investigates the antioxidant components [lycopene, total phenolics, flavonoids, ascorbic acid (AsA) and dehydroascorbic (DHA)] as well activities of hydrophilic lipophilic fractions (AAHF AALF) peel, pulp seed isolated from red-ripe berries ordinary tomato cultivar Rio Grande two high-lycopene breeding lines HLT-F61 HLT-F62 simultaneously grown in an open-field Northern Tunisia. Significant differences (p < 0.05) were found among cultivars for each trait studied. All HLT showed...
Introgression of spontaneous or induced mutations has been used to increase the levels and diversify profile antioxidants in many fruits including tomato. The high-pigment (hp) old-gold (og) alleles exemplify this approach as attractive genetic resources suitable inbred elite high-lycopene (HLY) tomato lines with improved color nutritional attributes. Although several studies have published on HLY tomatoes, a systematic analysis information their agronomic performances, processing features,...
The use of adequate organic fertilization is necessary to promote crop production. Organic nutrient sources including compost, manure, compost extract, and authorized fertilizers could be combined used in order achieve a balanced supply an improved tomato yield quality. purpose this study was compare the effect different fertilizer treatments on fruit physico-chemical properties two field cultivars. three were CODA: codahumus 20; COMP: 40 t ha−1 mixed (50% olive husk + 30% horse manure 20%...
Growing conditions and seasonal fluctuations are critical factors affecting fruit vegetable nutritional quality. The effects of two partially overlapping cropping seasons, early (ECS; January-May) full (FCS; March-July), on the main carpometric traits bioactive components different watermelon fruits were investigated in open field. Four genotypes, comprising three commercial cultivars 'Crimson Sweet', 'Dumara', 'Giza', novel hybrid 'P503 F1', compared. varied significantly between genotypes....
Abstract Tomato ( Solanum lycopersicon L.) fruit is rich in various nutrients, vitamins and health‐promoting molecules. Fresh tomatoes are an important part of the Mediterranean gastronomy, their consumption thought to contribute substantially reduced incidence some chronic diseases populations comparison with those other world areas. Unfortunately, tomato highly perishable, resulting economic losses posing a challenge storage, logistic supply management. This review summarizes current...
Organic tomato production is increasing worldwide, thus making necessary the development of varieties adapted to this farming system. It now well known that implementation local plant breeding programs for organic required increase performance in typology cultivation regime. In research, agronomic performance, nutraceutical contents, and radical scavenging activity a germplasm line (OSTGL), selected under organically grown conditions, were evaluated two consecutive years (2018 2019)...
This study investigates the antioxidant components (total carotenoids, lycopene, β-carotene, total phenols, flavonoids, ascorbic acid and vitamin C) as well hydrophilic lipophilic activities (HAA LAA) of tomato genotypes consisting one ordinary cultivar Rio Grande two high-lycopene breeding lines HLT-F71 HLT-F72. The correlation nutritional value to L∗, a∗, b∗ colour indexes a∗/b∗ ratio was also investigated in whole fresh cut fruits. Except for β-carotene content, significant differences...
Organic tomato cultivation is growing all over the world due to its healthy functional properties and environmental concerns. Recently, some new varieties with increased properties, particularly high lycopene, have been developed. However, few were assessed under organic farming systems. The objective of this study was evaluate physico-chemical main bioactive compound contents, as well lipophilic, hydrophilic total radical scavenging activities a recently developed lycopene variety...
In Tunisia, tomato (Solanum lycopersicum) is the most widely cultivated all year-round vegetable crop. Since 2011 abnormal yellowing symptoms have been observed on field grown crops in Kairouan, a major growing area Tunisia. These were uniformly distributed within fields. However at end of season it was difficult to distinguish between symptoms, and effects senescence other diseases that complicated matters. Initially confused with physiological nutritional disorders as has often occurred...
Both transgenic and conventional breeding methods have been used to increase levels diversify the profile of antioxidants in ripe tomato fruit. The high-pigment (hp) mutants exemplify this approach, representing useful genetic resources be introgressed into elite cultivars (high-lycopene cultivars) simultaneously enhance different classes antioxidants. Although several studies recently published on high-lycopene cultivars, information their horticultural performance, processing attributes...
