Citrus Rootstocks

Different metabolic and genetic responses in citrus may explain relative susceptibility toTetranychus urticae

“…Commercial citrus cultivars are always propagated vegetatively by grafting onto a rootstock. For a long time, sour orange ( Citrus aurantium L.) was the most widely used rootstock worldwide . In spite of its good agricultural properties, it has been progressively displaced from orchards because it is highly sensitive to the citrus tristeza closterovirus (CTV) .…”

Organogenesis and encapsulation of in vitro-derived propagules of Carrizo citrange [Citrus sinensis (L.) Osb. × Poncirius trifoliata (L.) Raf]

“…Propagation of Citrus rootstock is performed through openpollinated seed germination because most of the genotypes are highly polyembryonic and true-to-type plants can be obtained by nucellar embryos (Wutscher 1979). However, micropropagation is also an efficient propagation method, especially when shoot regeneration can be achieved by in vitro organogenesis, because it offers a number of advantages over conventional propagation methods, such as the possibility of obtaining a high number of true-to-type virus-free plants in relatively less time and in limited space (Barlass and Skene 1982).…”

Development of Tree Vigor Prediction Method at an Early Stage Based on Stem Hydraulic Conductance of Seedlings in Citrus Rootstocks

“…In citrus rootstock research, many selection tests have been carried out with the aim of accommodating rootstocks to their regional cultivation conditions and aptitudes, such as disease, salt stress, soil pH, tree vigor, and so on (Banus and Primo-Millo, 1995;Foner-Giner et al, 2003;Kawase et al, 1987;Roose et al, 1989;Wutscher, 1979). In Japan, trifoliate orange has been most commonly used for citrus rootstock.…”
