Grapefruit (Citrus paradisi Macf.) is an important cultivar of the Citrus genus which contains a number of nutrients beneficial to human health. The objective of the present study was to evaluate changes in bioactive flavonoids, antioxidant behaviour, and in vitro cytoprotective effect of processed white and pink peels after oven-drying (45°C-60°C) and freeze-drying treatments. Comparison with ...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

Proline accumulation was often correlated with drought tolerance of plants infected by arbuscular mycorrhizal fungi (AMF), whereas lower proline in some AM plants including citrus was also found under drought stress and the relevant mechanisms have not been fully elaborated. In this study proline accumulation and activity of key enzymes relative to proline biosynthesis (▵(1)-pyrroline-5-carboxy...

Volatile profiles yielded from gas chromatography-mass spectrometry (GC-MS) analysis provide abundant information not only for metabolism-related research, but also for chemotaxonomy. To study the chemotaxonomy of Mangshanyegan, its volatile profiles of fruit and leaf and those of 29 other genotypes of Citrus, Poncirus, and Fortunella were subjected to phylogenetic analyses. Results showed that...

Fourteen triethylamine derivatives including the 2-(4-chlorophenylthio)triethylamine (CPTA) were all found to be effective in inducing the formation of lycopene in Marsh white seedless grapefruit (Citrus paradisi, Rutaceae); however, they differed in the degree of effectiveness. The structural feature necessary for inducer activity appeared to be the tertiary alkylamine. Compounds with an S ato...

Grapefruit (Citrus paradisi) is an important cultivar of the Citrus genus which contains a number nutrients beneficial to human health. peels are usually thrown away in this part Nigeria. The research work investigated bioactive components present indigenous citrus peel, grape paradisi). Grape fruits were purchased from garden market D-Line, Port-Harcourt metropolis and washed with ionized wate...

A comparative study between the antioxidant properties of peel (flavedo and albedo) and juice of some commercially grown citrus fruit (Rutaceae), grapefruit (Citrus paradisi), lemon (Citrus limon), lime (Citrusxaurantiifolia) and sweet orange (Citrus sinensis) was performed. Different in vitro assays were applied to the volatile and polar fractions of peels and to crude and polar fraction of ju...

Citrus is grouped under the salt sensitive crops. Mycorrhizal fungi, a symbiotic relationship between plant roots and beneficial fungi, are supposed to impart the stress tolerance in the host plants. The stress tolerance improved due to Arbuscular Mycorrhizal fungi (AM fungi) colonization can be attributed to enhanced mineral nutrition. In the present study the efforts are made to evaluate the ...

Turunçgiller ülkemiz için hem üretim ve de ihracat bakımından en önemli meyve gruplarından biridir. içerisinde limonlar miktarı ilk sırada gelen türdür. Ülkemiz limon ihracatında İnterdonato, Lamas, Kütdiken Meyer çeşitleri yer tutmaktadır. Limonların kalite parametreleri ekolojiye göre farklılık göstermekle birlikte kullanılan anaç çeşitlerinin etkisi büyüktür. Ülkemizde yetiştiriciliğinde gen...
