The accumulation of arginine in leaves of four citrus rootstock cultivars during P deficiency has been demonstrated to be due to increased de novo synthesis rather than decreased catabolism or increased protein degradation (E Rabe, CJ Lovatt, 1984, Plant Physiol 76: 747-752). In this report, we provide evidence (a) that the increased activity of the arginine biosynthetic pathway observed for ci...

Citrus Huanglongbing (HLB) is becoming the most devastating citrus disease worldwide. Although no known HLB-resistant citrus species or varieties have been identified, some citrus accessions such as rough lemon are reportedly tolerant. To better understand the HLB tolerance or susceptibility mechanisms in citrus, comparative anatomical analyses of tolerant rough lemon and sensitive sweet orange...

Abstract: The objective of this work was to determine the influence eight rootstocks on yield, fruit quality, and survival 'Pêra CNPMF D6' sweet orange (Citrus sinensis) trees grown under rainfed conditions in a cohesive soil Brazilian Northeast. In 2014-2018, fruits, planted 1997 were evaluated randomized complete block design. Yield assessed using annual production, yield efficiency, alternat...

Polyploidy, frequently observed in citrus species, aids achieving better adaptation to environmental stresses. In this context, the current work aims develop stable tetraploids rootstock cultivars, viz., Rough lemon, Rangpur lime and Alemow, through vitro colchicine treatments. Seed-derived explants were obtained by culturing sterile seeds on MS basal media. Seedlings with a size of 5–8 mm (hyp...

‘Hafif Çukurgöbek’ loquat budded on three quince rootstock (BA-29, A, and C) were evaluated in 2018 2019 Hatay, Turkey. Fruit ripening was the earliest BA-29 both years. The highest fruit weight obtained from Quince-C followed by rootstock, Quince-A rootstock. yielded significantly higher values terms of seed number, weight, flesh/seed ratio. rootstocks had similar total soluble solids, while l...

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...

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...
