Abstract EN
Endemic Muscari muscarimi Medikus is most fragrant plant among Muscari species and has high ornamental potential.
The natural populations of M.
muscarimi, is severely affected by increased environmental pollution and urbanization.
There is need to develop a micropropagation method that should serve effectively for commercial propagation and conservation.
Therefore, the study targeted to set up a strategy for efficient in vitro bulblet regeneration system of M.
muscarimi using twin scale bulb explants on 1.0 • MS medium containing 4.44, 8.88, 17.76 lM BAP (6-Benzylaminopurine) plus 2.685, 5.37, 10.74 lM NAA (a-Naphthalene acetic acid).
Maximum number of 19 daughter axillary bulblets and 16 daughter adventitious bulblets per twin bulb scale explant was regenerated on 1.0 • MS medium containing 17.76 lM BAP plus 10.74 lM NAA and 17.76 lM BAP plus 2.685 lM NAA respectively.
The daughter bulblets regenerated on twin bulb scales on 8 out of 9 regeneration treatment could be easily rooted on 1.0 • MS medium containing 4.9 lM IBA (Indole-3-butyric acid).
The daughter bulblets regenerated 9th treatment (1.0 • MS medium containing 17.76 lM BAP plus 10.74 lM NAA) were transferred to 1.0 • MS medium containing 30 g / l sucrose to break negative carry over effect of this dose of BAP-NAA, where they grew 2-3 roots of variable length.
Daughter bulblet diameter was increased by culturing them on 1.0 • MS medium containing 4.44 lM BAP plus 5.37 lM NAA.
The results verified that both age and the source of explants had significant effect on regeneration.
In another set of experiments, twin scales were obtained from in vitro regenerated daughter bulblets, although they induced bulblets, yet their bulblet regeneration percentage, mean number of bulblets per explant and their diameter was significantly reduced.
In vitro regenerated bulblets were acclimatized in growth chamber under ambient conditions of temperature and humidity on peat moss, where they flowered.
The study provides important information about selection of suitable micropropagation medium, strategies to improve bulblet diameter and rooting of M.
muscarimi which offers a scope for commercial propagation.
