Cleopatra Mandarin

Young orange [Citrus sinensis (L.) Osbeck ‘Pineapple sweet orange’] trees are more sensitive to bromacil (5-bromo-3-sec-butyl-6-methyluracil) than young mandarin (Citrus reticulata Blanco ‘Cleopatra mandarin’) trees. Pineapple sweet orange roots absorbed twice as much 14C from bromacil, and accumulated three times as much in the leaves, as did Cleopatra mandarin. The amount of conjugated metabolites formed was the same in the roots of the two cultivars, but twice as much formed in the leaves of Cleopatra mandarin as in the leaves of Pineapple sweet orange. The principle metabolite was 5-bromo-3-sec-butyl-6-hydroxymethyluracil; a minor metabolite was tentatively identified as 5-bromo-3-(3-hydroxyl-1-methylpropyl)-6-methyluracil. No 5-bromouracil was detected. Citrus cultivars differ in their ability to accumulate and metabolize bromacil into conjugated nonphytotoxic compounds.

Friable Callus

Nucellar tissues of seven Citrus varieties were introduced onto three growth media to produce embryogenic callus. The media tested were: EME [MT, modified, with the addition of malt extract (500 mg.L-1)]; 1/2-EME [half concentration of MT macronutrients + half concentration of BH3 macronutrients + 500 mg.L-1 malt extract + 1.55 g.L-1 of glutamine]; and EBA [EME + 0.44 muM 6-benzyladenine + 0.04 muM 2,4 D]. Soft friable calli were obtained from 'Cravo' and 'Ponkan' mandarins (Citrus reticulata, Blanco), 'Murcott' tangor (Citrus reticulata Blanco x Citrus sinensis L. Osbeck), 'Serra d'água' and 'Valencia' sweet oranges (Citrus sinensis, L. Osbeck) 120 days after callus induction. 'Natal' and 'Pera' sweet oranges (Citrus sinensis, L. Osbeck) produced hard non-friable calli in this period. EME and 1/2-EME media had the best results for 'Cravo' mandarin, 'Ponkan' mandarin and 'Serra d'água' sweet orange, whereas EBA was the best media composition to induce soft friable calli on 'Murcott' tangor and 'Valencia' sweet orange. Friable callus cultures of 'Cravo' and 'Ponkan' mandarins, and 'Murcott' tangor yielded high quality protoplasts after isolation. Abbreviations: a.c. - activated charcoal; BA - 6-benzyladenine; IAA - indole-acetic acid; 2,4-D - 2,4-diclorophenoxyacetic acid; MT - Murashige & Tucker basal medium.
