Effect of Piper betle leaf extract on post-harvest physiology and vascular blockage in relation to vase life and keeping quality of cut spike of tuberose (Polianthes tuberosa L. cv. Single)

Evaluation of Piper betle mediated silver nanoparticle in post-harvest physiology in relation to vase life of cut spike of Gladiolus

“…There was a relation between fresh weight and solution uptake during vase life. Similar relationships have also been reported by earlier workers (Bieleski and Reid 1992;Borochov et al 1995;Maity et al 2014) in daylily, rose, and tuberose. The vase life, the fresh weight of cut spikes, and microbial load resisted in xylem vessel by the use of PbSNPs and helped to maintain the water uptake by floral spike.…”

“…Vase solution is widely used for the extension of vase life. Thus, effect of PbSNPs in vase solution perhaps exhibited the similar mechanism which is also observed in tuberose spike when Piper betle extract was used in vase solution (Maity et al 2014) or 8-hydroxyquinoline sulphate (8-HQS) used for snapdragon (Asra 2012). The previous results showed that adding sucrose increased the vase life if the growth of microorganisms was controlled (Ezhilmathi et al 2007;Moneruzzaman et al 2010;Saeed et al 2016).…”

“…The antimicrobial effect of SNPs is due to structural changes of the bacterial cell membrane, blockage of DNA replication, the debauchery of proton motive force, and finally cell death (Solgi et al 2009;Solgi 2014). Antimicrobial activity of plant-mediated synthesized SNPs reported earlier (Kaviya et al 2011;Maity et al 2014;Solgi 2014;Yugandhar et al 2015). Thus, the PbSNPs appeared to be an effective antibacterial agent that significantly reduced the bacterial growth in vase solution as well as vascular blockage in cut spike with its increasing concentration.…”

“…Final crude extract was concentrated and dried by rotary vacuum evaporator at a temperature less than 50°C following concentrated extract which was maintained at 4°C. Working PbLE stock solution of concentration 10 mg/ml was prepared by dissolving 100-mg dried crude extract in 500 μL of dimethyl sulfoxide (DMSO) and further diluted with distilled water (Maity et al 2014).…”

Assessment of Cisplatin, Etoposide, Vinblastine and <i>Piper betle</i> Leaf Extract on Some Attributes of Cell Division in <i>Lathyrus sativus</i> L.

“…The PbLE extract is prepared as per Maity et al (2014). For this purpose, freshly cut betel leaves (Kali Bangla, landrace of Paschim Medinipur, West Bengal) were dried in a hot air oven (40 1 C) for 48 h, crushed with a mortar and pestle and the dust was stored at 20 C. The dust was Soxhlet extracted using 80% ethanol for 20 h. The crude extract was concentrated and dried in a rotary vacuum evaporator below 50 C. The dried extract (100 mg) was dissolved in 500 µL of dimethyl sulfoxide (DMSO) and then diluted to a 10 mg/mL working PbLE stock by adding triple distilled water by 10 mg/mL basis.…”
