Nodal segments from mature olive (Olea europaea L.) plants of 'Arbequina' were successively micrografted (up to five times) onto juvenile rootstoks. The in vitro rooting competence of regenerated shoots increased from 13 to 61 % from the first to the fifth micrograft respectively. Rooted plants were acclimated under a plastic tunnel and transferred to the greenhouse; after two years these plants were used as source of cuttings for conventional propagation. Micropropagated plants were also analysed by using the SSRs technique and showed to be true to type. Cuttings obtained from donor plants of the fifth micrograft showed a rooting percentage of 92%. This study indicates that revitalization of adult material through micrografting can increase the rooting capacity of cuttings derived from the rejuvenated plants. Source

The aim was to study the performance of Navelate sweet orange on five rootstocks: Carrizo citrange [Citrus sinensis (L.) Osb. × Poncirus trifoliata (L.) Raf.]; Cleopatra mandarin (C. reshni Hort. ex Tan.); C. volkameriana Ten. & Pasq. and two new hybrids C-13 (C. depressa Hay. × P. trifoliata) developed at the University of California Citrus Research Center and 020326 [Troyer citrange (C. sinensis × P. trifoliata) × Cleopatra mandarin] developed at the Instituto Valenciano de Investigaciones Agrarias in Valencia, Spain. The investigation was conducted in Almería, Spain. The soil was sandy, with pH>8 and electric conductivity in the saturation extract below 4.5 mmhos cm -1. The design was a complete-block with randomised singletree plots and eight replications. Tree spacing was 4.5 m × 4 m. Yield was recorded during the first nine harvests, fruit quality was determined for the 5 th, 6 th and 9 th harvests and tree size was evaluated 11 years after planting. Trees on C. volkameriana rootstock produced the highest yield and largest fruits. Trees on the C-13 hybrid selection were the most yield-efficient on a canopy volume basis, and had fruit with the highest soluble solid content, but there were few differences between rootstocks for the latter parameter. Cleopatra mandarin and 020326 induced the lowest individual fruit weight and diameter. Source

This study, carried out in Almería (Spain), evaluates the performance of 'Clausellina' mandarin on four rootstocks: Carrizo citrange [Citrus sinensis (L.) Osb. x Poncirus trifoliata (L.) Raf.]; C. volkameriana Ten. and Pasq.; and, the two new hybrids 'C-13' (C. depressa Hay. x P. trifoliata) obtained at the University of California Citrus Research Center and '020326' [Troyer citrange (C. sinensis x P. trifoliata) x Cleopatra mandarin] obtained at the Instituto Valenciano de Investigaciones Agrarias in Valencia (Spain). Soil was sandy, with pH>8 and electric conductivity below 4.5 mmhos cm-1 in the saturation extract. Yield was weighed during the first nine harvests, fruit quality was determined in the 5th and 9 th harvests and tree size was evaluated annually from 3 to 11 years after planting. Trees on C. volkameriana rootstock were biggest and produced the highest yield, followed by trees on Carrizo citrange. Trees on the C-13 hybrid selection were most efficient in yield m-3 of canopy volume. There were few differences between rootstocks in terms of fruit quality. Source
