The biology of the citrus psyllid Diaphorina citri Kuwayama was studied at 25 degrees C on four commonly grown citrus and related plants [rough lemon, Citrus jambhiri Lush; sour orange, C aurantium L.; grapefruit, C. paradisi Macfadyen; and orange jessamine, Murraya paniculata (L.) Jack] in the laboratory. The biological characteristics of each life stage are described. The average egg incubati...

Hypoxia is a potential threat to various horticultural cropsin lands prone to flooding. Citrus is mostly known as a sub-tropical crop that is often exposed to environmental stresses. In order to evaluate response of six different citrus genotypes, including sour orange, rough lemon, Trifoliate orange, Troyer citrange and two local genotypes labeled; CRC1 and CRC2 to flooding conditions, an expe...

The biology of the citrus psyllid Diaphorina citri Kuwayama was studied at 258C on four commonly grown citrus and related plants [rough lemon, Citrus jambhiri Lush; sour orange, C. aurantiumL.; grapefruit,C.paradisiMacfadyen; andorange jessamine,Murrayapaniculata(L.) Jack] in the laboratory. The biological characteristics of each life stage are described. The average egg incubation periods on o...

Lemon is a prominent citrus fruit that supports regional economies worldwide. Several agronomic and quality attributes are affected by the rootstock selection, thus its selection essential for successful grove. This study aims to compare of four lemon cultivars (‘Mikrokarpo Messaras’, ‘Nouvel Athos’, ‘Femminello Commune,’ ‘Zia gara Bianca’) grafted onto three rootstocks (‘Sour Orange’, ‘Yuma Po...

Sweet and sour cherries contain several polyphenols that possess antioxidant and anti-inflammatory properties. Aim of this study was to investigate the effect of the maturity stage on phenol content and biological properties of extract of a local Morello-type of sour cherry (Prunus cerasus L.), “visciola”. The study of total phenol content and total antioxidant potential was associated with the...

The suitability of Beidler's mixture equation for mixtures of sucrose and maltitol as well as for mixtures of sucrose and aspartame was examined in the presence of an orange aroma. The mean scores for the attribute sweet remained constant for each combination of sucrose and maltitol and for each combination of sucrose and aspartame. Therefore, Beidler's mixture equation can be used to choose co...

Recent research suggests that systemic signalling and communication between roots and leaves plays an important role in plant defence against herbivores. In the present study, we show that the oviposition of the two-spotted spider mite Tetranychus urticae in the systemic leaves of citrus rootstock Citrus aurantium (sour orange) was reduced by 50% when a lower leaf was previously infested with c...

based on the valuable antioxidant activity of citrus fruits, in present study the effect of ‎rootstock and the type of tissue on some fruit quality parameters including phenol, ‎flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin ‎was studied. the experiment was conducted as a factorial design based on complete ‎randomized blocks with four replications. resu...
