“…In recent years, even though vast and multifarious investigations have been conducted to examine the impacts of PGRs on regenerating plants under in vitro and in vivo conditions (Small and Degenhardt 2018;Babu et al 2022), there have been limited studies on the genus Sternbergia and especially SC (Oran and Fattash 2005). To the best of our knowledge, despite the present research, the only report that exclusively discloses the importance of reproducing a species of this genus by making use of PGRs and vegetative techniques is related to Nazari (2019).…”

“…Plant growth regulators (PGRs), i.e., phytohormones, are signal molecules generated inside the cells, triggering or inhibiting particularized enzymic synthesis to regulate plant metabolism. Phytohormones are known to be imperative for plant growth and development (Babu et al 2022). Nonetheless, it is critical to mention that the production of PGRs within plants is in inordinately low amounts, thereby being active normally in very low dosages.…”

Sternbergia clusiana (SC) is a bulbous plant having an alluring ornamental flower, medicinal properties, and an endangered status due to climate-change ecology. However, the methods of propagation for conserving this notable species have been neglected. The main aim of this study was to evaluate the influence of plant growth regulators (PGRs) on SC regeneration by virtue of an asexual propagation method, with the intention of preserving this endangered species from extinction. In this regard, having collected the bulbs from a wild habitat, bulbs were cut in accordance with the chipping technique. Thereafter, pieces were treated with 6-benzylaminopurine (BAP) at 250, 500, and 1000 mg L-1, 1-naphthaleneacetic acid (NAA), at 100, 250, and 500 mg L-1, putrescine (PU) at 50, 100, and 200 mg L-1, BAP and NAA combination, BAP and PU combination, and a control. Pieces were then transferred into primary and terminal growing media under laboratory and greenhouse conditions, respectively. Next, the number, length, width, and weight of bulbs were determined. The greatest bulb number (2.10 count), bulb length (26.75 mm), bulb width (16.25 mm), and bulb weight (3.13 g) were observed in the PU treatments. In addition, the results showed that even though the treated bulbs with BAP and PU combinations had preferable performance generally, the results were inconsistent. Taken together, this research indicates that utilizing asexual propagation along with PGRs, in the proper dosage, can serve as a mechanism to protect the endangered geophyte from extinction in nature.
