Bulb cutting methods to propagate Hippeastrum hybridum Hort.

Alkaloids Analysis of Habranthus cardenasianus (Amaryllidaceae), Anti-Cholinesterase Activity and Biomass Production by Propagation Strategies

“…The lowest multiplication rate was observed in T0 (control, whole bulb without cuts) and T5 (seed propagation) (0.76 ± 0.17 and 0.48 ± 0.11 bulbils per mother bulb, respectively) (Figure 3B). Andrade-Rodriguez et al [16] reported similar findings, indicating that the presence of the main bud in the bulbs inhibited the development of new bulbils, whereas complete longitudinal cuts promoted bulbil production. Additionally, Witomska et al [22] showed that cuts in the basal disc are essential to stimulate bulbil production.…”

“…The different propagation methods had a significant influence on survival: T0 (control, whole bulb without cuts) and T1 (bulb quarters) presented the highest percentage of surviving bulbils (76 ± 6.73 % and 61 ± 6.52%, respectively) and T3 (twin scales) the lowest (Figure 3A). Witomska et al [22] reported that the reserves in the cataphylls of the mother bulb play an important role in the survival of new bulbils [16].…”

Witomska et al [22] reported that the reserves in the cataphylls of the mother bulb play an important role in the survival of new bulbils [16]. Another parameter significantly affected during the propagation assays was the multiplication rate, which was highest in T1 (bulb quarters) and T2 (twin scales) (2.44 ± 0.26 and 2.20 ± 0.42 bulbils per mother bulb, respectively).…”

“…According to Kharrazi et al [20] and Letelier & Cabello [21], large bulb fractions have greater reserves and so generate larger bulbils. Also, Andrade-Rodriguez et al [16] reported that the biggest bulbils were obtained after applying the four longitudinal section treatment, whereas the smallest bulbils were produced by the twin cataphyll method.…”

“…Amaryllidaceae species, including Habranthus cardenasianus Traub & I.S. Nelson, are not abundant, and present a low natural multiplication rate [16]. Mining and agricultural activities, together with urban growth, are reducing the populations of plants in this family.…”
