The regeneration capacity of six types of explants (segments from hypocotyl, cotyledons, epicotyl, leaf, internodes and petiole) was compared in 13 cultivars of tomato (Lycopersicon esculentum Mill). Explants were cultured on a regeneration medium containing 1 mg/l zeatin and 0.1 mg/l indole-3-acetic acid. The number of shoot primordia and shoots with 1 or more fully developed leaves was evaluated after 6 weeks. The regeneration capacity was significantly influenced by cultivars and explant types. The total number of shoot primordia produced in all types of explants was highest in the cultivars Hana and Premium and lowest in UC 82 and Money Marker. Cv. Hana also produced the highest number of shoots. The most responsive explants in most cultivars were hypocotyls and epicotyls with up to 100% regeneration and mean production of 6.3 and 6.5 shoot primordia per explant, respectively.

Indole 3 Acetic Acid

Explants were obtained from leaves of three strains of tomato and grown on a modified Murashige and Skoog's medium with various combinations of indole-3-acetic acid (IAA) and kinetin. Callus proliferation began by 8–10 days. Root initiation was very common, particularly at 2 mg/liter IAA and 2 mg/liter kinetin. Shoot formation occurred within 30 days but only at a specific combination of concentrations of the two growth hormones (4 mg/liter IAA + 4 mg/liter kinetin). Most shoots became plantlets by 10 days after transfer to basal Murashige and Skoog's medium. Shoot-forming potential was neither correlated with callus-forming potential nor with vigor of strain.

Indole 3 Acetic Acid

An in vitro system was used for the production of tomato (Lycopersicon esculentum) fruit in culture starting from immature flowers. This system produced small parthenocarpic (seedless) fruit in response to 10-4m indole-3-acetic acid (IAA) supplied in the medium. Other auxins, auxin conjugates and antiauxins tested were not effective or produced markedly fewer fruit. Additional IAA supplied to the fruit culture media before breaker stage resulted in an increase in the time period between breaker and red-ripe stages from 7 days without additional IAA to 12 days when 10-5m IAA was added. These results suggest that significant changes in the ripening period could be obtained by alteration of auxin relationships in tomato fruit.
