Abstract Huanglongbing (HLB) disease, causes a 60-95% decline in Indonesia citrus production almost all centers. The use of suitable interstocks can increase fruit and quality, improve compatibility, also tolerance to HLB with tolerant interstocks. Potential interstock, providing an alternative for farmers be able save their plants from the destruction HLB. purpose this study was determine effe...

The response of Citrus spp. and related rootstocks to a population of Meloidogyne javanica was evaluated in a screenhouse experiment. Palestine and Rangpur lime, rough lemon, sour orange, Sexton and Thentriton tangelo, and Volkamer lemon were not infected by M. javanica. Galls and tip swellings were observed on the roots of Poncirus triloliata and Troyer citrange. There was no evidence of nemat...

UNLABELLED Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and tetraploid (4x) plants of Carrizo citrange (Citrus sinensis L. Osb. × Poncirus trifoliata L. Raf.), a widely used citrus rootstock. Wit...

Four biotypes (pathotypes) of the citrus nematode, Tylenchulus semipenetrans, occurring in California, U.S.A. were differentiated on the basis of differences of infectivity on 'Homosassa' sweet orange, 'Troyer' citrange, 'Pomeroy' and 'Rubidoux' Poncirus trifoliata, 'Thompson Seedless' grape, and 'Manzanillo' olive. A method for differentiating biotypes of T. semipenetrans is described. Field o...

Carrizo citrange (Citrus sinensisxPoncirus trifoliata) is a citrus hybrid widely used as a rootstock, whose genetic manipulation to improve different growth characteristics is of high agronomic interest. In this work, transgenic Carrizo citrange plants have been produced overexpressing sense and antisense CcGA20ox1 (a key enzyme of GA biosynthesis) under control of the 35S promoter to modify pl...

Citrus are one of the most relevant fruit crops in Mediterranean basin, which is second-highest citrus-growing region world. However, these mainly grown under semi-arid conditions, characterized by long periods drought and torrential rain. In this work, we have assessed response three promising HLB-tolerant citrus rootstocks (Orange-14, UFR-1, B11R3T27) to application four water stress conditio...

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...
