Abstract
SummaryRegeneration of shoots from in-vitro grown leaf tissues of the pear cv. Conference was achieved at rates of up to 40%. The highest regeneration percentage was achieved using a phytohormone combination of benzylamino purine (5 mg 1−1) and 1-naphthalene acetic acid (1.0 mg 1−1) on a basal medium of Murashige and Skoog, to which had been added 200 mg I−1 of the antibiotic cefotaxime. The percentage regeneration was reduced when a higher concentration of cefotaxime (400 mg 1−1) was used. Cefotaxime had little beneficial effect on regeneration at a lower concentration of 1-naphthalene acetic acid (0.5 mg l−1). Regenerated shoots were easily micropropagated, rooted and transplanted to soil. To date, the plants have a true-to-type phenotypic appearance. Regeneration was also achieved with other cultivars—‘Abbé Fetel’, ‘Doyenne d’Hiver’, ‘Doyenne du Comice’ and ‘Passé Crassane’—but percentage regeneration was lower and, apart from ‘Passé Crassane’, the regenerated shoots were weak and could not be subcultured.
