Influence of Ethylene and Kinetin on Tuberization and Enzyme Activity in Solanum tuberosum L.

In vitro corm production in the saffron crocus (Crocus sativus L.)

“…The combined effect of microsurgery of the apical bud and ethylene pretreatment, in breaking the apical dominance, yielded more sprouting buds than the Table 3. additive number of both treatments; all of the sprouting buds developed into corms. Similar effects of ethylene were reported for Iris lortetti, where ethylene treatment of isolated buds in vitro induced the development of both axillary and adventitious buds [28], for hyacinth [25] and for potatoes [26]. In Lilium speciosum, ethylene biosynthesis and adventitious bud formation were found to be correlated [29], giving further support to the effect of ethylene in bud sprouting and storage organ formation in vitro and its role in vivo.…”

“…Gladiolus grandiflorus [22,23] as well as other geophilous organs on other mono-and dicotyledonous geophytes in vitro [24,25,26].…”

Is dormancy breaking of potato tubers the reverse of tuber initiation?

“…Also Mauk & Langille (1978) found a stimulation of tuberization when using zeatin riboside (ZR) in the medium of an in vitro tuberization system. Cytokinins are also involved in regulating enzyme activities of carbohydrate metabolism (Palmer & Barker, 1973).…”

Effects of ethylene on the tuberization of potato (Solanum tuberosum) cuttings

“…Dimalla and Van Staden [5] reported that ethylene prevented 'little-tuber disorder', i.e ., the formation of small tubers on aged mother tubers . Palmer and Barker [17] and Koda and Okazawa [10] noticed diageotropic growth of shoots after treatment with ethylene in vitro, but they found no effect on tuberization .…”
