“…With respect to the position at the stem, the shoot tip is located above the inhibited axillary bud, and the rhizome tip below. Bond and Alderson (1993) have reported that both shoot and rhizome tips control the outgrowth of the 2 nd axbud, but that the auxin transport inhibitor TIBA has no effect. They conclude that the mechanism of apical dominance in Alstroemeria is complicated.…”

We study apical dominance in Alstroemeria, a plant with an architecture very different from the model species used in research on apical dominance. The standard explant was a rhizome with a tip and two vertically growing shoots from which the larger part had been excised leaving ca. 1 cm stem. The axillary buds that resumed growth were located at this 1-cm stem just above the rhizome. They were released by removal of the rhizome tip and the shoot tips. Replacement of excised tips by lanolin with indole-3-butyric acid (IBA) restored apical dominance. The auxin transport inhibitors 2,3,5-triiodobenzoic acid (TIBA) and N-1-napthylphthalamic acid (NPA) reduced apical dominance. 6-Benzylaminopurine (BAP) enhanced axillary bud outgrowth but the highest concentrations (> 9 µM) caused fasciation. Thidiazuron (TDZ) did not show improvement relative to BAP. Even though the architecture of Alstroemeria and the model species are very different, their hormonal mechanisms in apical dominance are for the greater part very similar.

“…This kind of propagation is time consuming and contributes to the spread of virus diseases. Therefore in vitro propagation has been developed to accelerate the multiplication efficiency (Gabryszewska and Hempel, 1985;Hakkaart and Versluijs, 1988;Ven Zaayen et al, 1992;Bond and Alderson, 1993). Flower pedicels subapical, segments from the vegetative stem and rhizome buds of Alstroemeria were tested as initial explants.…”

Alstroemeria with beautiful and long shelf life of cut flower is one of the most important ornamental plants. This plant could propagate by splitting of the in vivo produced rhizomes but the propagation rate is rather low. In the present study, regeneration ability of plantlets was compared using in vitro and in vivo grown rhizome buds as explants. In vitro and in vivo grown rhizome buds were cultured on MS basal medium with 3 different compositions of growth regulators (1, 0.2 mg l-1 NAA with 1 mg l-1 BA and 0.2 mg l-1 IAA with 1 mg l-1 BA). Cultures were incubated in 18 ± 1°C at 16 h photoperiod. Four subculture of explants were done on the same fresh media with 3 weeks intervals. The results showed that in vivo rhizome bud produced the largest number of small rhizome and roots on medium containing 0.2 mg l-1 NAA with 1 mg l-1 BA.

“…These data indicate that both aerial shoots and the rhizome tip inhibited axillary-bud outgrowth in Alstroemeria. This corresponds to the previous observation by Bond and Alderson (1993).…”

“…This suggests that both tips exert apical dominance over axillary buds, thus preventing branching in Alstroemeria. However, addition of the auxin transport inhibitor 2,3,5-triiodobenzoic acid (TIBA) in the culture media does not lead to an increased multiplication rate, suggesting that the mechanism of apical dominance in Alstroemeria is a complex phenomenon (Bond and Alderson, 1993). These data imply that a better understanding of how apical dominance controls axillary bud outgrowth is required for improvement of Alstroemeria propagation.…”

“…Recently, evidence has been obtained for the occurrence of a carotenoid-like, inhibitory regulator (Mouchel and Leyser, 2007). Bond and Alderson (1993) report that removal of both aerial shoot and rhizome tips significantly increases rhizome branching. This suggests that both tips exert apical dominance over axillary buds, thus preventing branching in Alstroemeria.…”

Apical dominance in Alstroemeria is studied to develop an improved propagation protocol for this crop. Four types of explants were prepared: an intact rhizome with two intact shoots (+R+2S), an intact rhizome with two decapitated shoots (+R-2S), a decapitated rhizome with two intact shoots (-R+2S), and a decapitated rhizome with two decapitated shoots (-R-2S). The explants were cultivated on solid MS medium with 9 µM 6-benzylaminopurine (BAP). -R-2S explants showed the highest and +R+2S the lowest axillary-bud outgrowth. Outgrowth in -R+2S and +R-2S explants was intermediate. So, axillary buds are released by removal of the rhizome tip and by removal of the shoot tips. In both decapitated shoots and decapitated rhizomes, application of lanolin with 3-indolebutyric acid (IBA) to the cut end restored apical dominance. This indicates that both tips exert an effect via basipetally transported auxin.
