“…Similar shoot bud regeneration on roots has been previously reported for a number of genera including Convolvulus [3,4,8,19], Linaria [6], Chondrilla [12], lsatis [7], Comptonia [ 10], and Ipomoea [ 11 ].…”

“…Although for Ipomoea batatas shoot formation has been reported directly on callused primary storage root explants [11,21], no clear cut cases of shoots emerging from calli or explants unassociated with a de novo formed root were found in our experiments. In another study shoot buds were initiated on roots in culture [15], but bud development was arrested in a primordial stage.…”

“…In vitro plantlet regeneration of sweet potato (Ipomoea batatas L.) has been reported utilizing storage root tissue [11,21], leaf tissue [18], and meristem tip culture [1,9,13,17]. In those studies regeneration occurred only from primary explants, and except for the meristem cultures, quantitative data were not presented.…”

Explants from stem, leaf, and storage root tissue of sweet potato (lpomoea batatas L.) cv. Jewel, were placed on media conairdng 0.1, 1.0, and 10mg/INAA with 0.1, 1.0, or 10 mg/IBA in a factorial experiment. Some callus formed in every treatment, but the best callus growth was on media containing 1.0 mg/1NAA and 10 mg/1BA. Roots formed over a range of treatments but were most prolific on the medium containing 1.0 mg/1NAA and 0.1 mg/IBA. Some de novo formed roots subsequently produced shoot buds in culture. Shoot formation increased the longer the original explants remained in culture without subculture. Roots could be subcultured indefinitely on agar solidified medium, but shoot regeneration did not occur after two subcultures. Shoot formation was greatest when the roots were subcultured on medium containing 1.0 mg/NAA and 0.1 mg]lBA. The cultivar 'Caromex' followed the same regeneration pathway, but the number of shoots formed was considerably less. Regeneration in both 'Jewel' and 'Caromex' explants was enhanced by light.

“…Many reports on the reproduction of sweet potato plants in vitro were characterized by a low frequency of shoot formation and long culture periods ( Gunckel et al, 1972;Hwang et al, 1983;Carswell et al, 1984;Murata et al, 1987;Lowe et al, 1992;Ramana et al, 1995). Shoots are difficult to produce by tissue culture using storage roots (Yamaguchi et al, 1979), although adventitious shoots can be formed (Yamaguchi et al, 1972(Yamaguchi et al, , 1978.…”

(2,4-D) and kinetin on the callusing and the organogenesis in vitro of internode fragments of two varieties of sweet potato (Ipomoea batatas L. Lam.). The object of the study was the influence of indole 3 acetic acid (IAA), naphtalene acetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D) and kinetin, applied separately or in association, on the callusing and organogenesis in vitro of internode fragments of 2, "white" and 'pink' ; varieties of sweet potato in relation to the polarity of explants and the varietal character.The different callusing and organogenesis potentialities of the explants have been analysed. The neoformation of roots and buds growing into plants has been obtained.The in vitro tuberization of the neoformed roots has been also obtained. It exclusively occurs in the presence of kinetin and auxin.The agronomic interest of these results for the practice of the vegetative propagation of sweet potato is underlined.Growth regulator -Ipomoea batatas -polarity -callusing -organogenesis -tuberization
