“…Cut gladiolus flowers highly rank in global floral markets with consistent demand throughout the year due to their unique ornamental value [ 1 ]. Thus, the demand for cut gladiolus continues to increase not only for local use, but also for export purposes in some countries [ 1 , 2 ]. However, maintaining cut flower quality is an important challenge for growers globally [ 3 ].…”

“…In view of these challenges, the use of plant-derived biostimulants in horticultural crops has increased due to the economic, environmental, and biological advantages [ 7 , 8 ]. Among biostimulants, natural bioactive substances such as moringa ( Moringa oleifera ) leaf extract (MLE) have been shown to improve the pre- and post-harvest quality of horticultural crops [ 1 , 2 , 8 ]. The foliar application of MLE at various development stages of gladiolus not only improved the flowering quality, but also enhanced the post-harvest quality and longevity [ 1 ].…”

Gladiolus is in demand worldwide as a cut-flower or landscaping plant, because of its superior commercial and ornamental value. Application of plant-based biostimulants has gained interest in the horticulture industry as an innovative and promising approach to ensure enhanced and sustainable yields along with better product quality. The influence of pre-plant corm soaks supplemented to 5% (v/v) with an aqueous extract from Moringa oleifera leaves (MLE) either alone or in combination with 50 mg/L salicylic acid (SA) or 50 mg/L gibberellic acid (GA) on the vegetative, physiological, and ornamental characteristics of potted gladiolus (Gladiolus grandiflorus) was investigated. In general, the treatment order for greatest horticultural value for all the parameters examined was: MLE + SA + GA > MLE + GA or SA individually > MLE alone > water-only control. Compared to other treatments, corms soaked in MLE + SA + GA had the earliest sprout time (3.7 days earlier than control), shortest production time (11 days earlier than control), tallest plant (159.5 cm), greatest number of leaves per plant (8.85 leaves), greatest maximum leaf area (66 cm2), highest SPAD reading (112) and photosynthetic activity (6.7 mmol m−2 s−1), longest spike length (91 cm), greatest number of florets per spike (20 florets), longest vase life (14.8 days), greatest N (1.53%), P (0.28%), and K (0.64%) concentrations, and largest corm diameter (4.68 cm) and mass (22.25 g). The highest total protein and proline concentrations were observed with the combined application of MLE + GA + SA. Our findings suggested that MLE either alone or in combination with other plant growth regulators not only increased the yield and quality of cut spikes, but also prolonged the vase life of cut gladiolus.

“…In view of our results, the flower senescence in carnation may be regulated by 1-MCP, AgNPs, or SNP that resulted in maintaining the membrane stability and reducing lipid peroxidation. During the flower vase life, 1-MCP, AgNP, and SNP treatments increased the MSI and reduced the accumulation of MDA compared with untreated flowers (Hassan & Fetouh 2019;Hassan et al 2020). The lipid peroxidation reduction and maintenance of the membrane stability have been elucidated to be reversely proportional with cut flower senescence Ali et al 2018).…”

Postharvest senescence is a critical problem of carnation cut flowers, limiting their transportation and subsequent marketing chain. This study was designed to assess whether the application of 1-methylcyclopropene (1-MCP), silver nanoparticles (AgNPs), and nitric oxide (NO) released from donor sodium nitroprusside (SNP) could prolong the vase life of cut carnations through an influence on the physiological and biochemical mechanisms involved in aging process. 1-MCP was used in the concentrations of 0, 100, 200, and 300 mg·m−3; AgNPs in the concentrations of 0, 50, 100, and 150 mg·dm−3; and SNP in the concentrations of 0, 0.1, 0.2, 0.3, and 0.4 mM. All treatments significantly extended the cut flower life compared with untreated flowers, more so with 300 mg·m−3 of 1-MCP, 100 mg·dm−3 of AgNPs, or 0.3 mM of SNP. All these chemical compounds were able to considerably improve the relative water content (RWC), reduce the malondialdehyde (MDA) content and increase the membrane stability index (MSI) in petals and, therefore, maintain the membrane integrity. In addition, they decreased the activities of acetyl-CoA synthetase (ACS) and nitric oxide synthase (NOS) and, hence, depressed the production of ethylene in carnation cut flowers through downregulating the ethylene production, what prolonged the vase life. Altogether, the application of exogenous 1-MCP, AgNPs, or SNP may provide a promising avenue to improve the postharvest performance of carnation cut flowers.

“…Bu çalışmalarda, antimikrobiyal etkilere sahip olduğu bilinen gümüş tiyosülfat (STS), gümüş nitrat (AgNO 3 ), hidroksikinolin sülfat (8-HQS), hidroksikinolin sitrat (8-HQC) gibi birçok kimyasal madde kullanılmış ve gerberanın vazo ömrünü uzatmada oldukça etkili oldukları belirlenmiştir (Khan et al, 2015;Mohamed et al, 2018, Sharma et al, 2018. Ancak son yıllarda hem doğal hem insan sağlığına zarar vermeyen hem de çevre dostu olan bitki ekstraktlarının da vazo ömrünü uzatmak amacıyla kullanıldıkları ve oldukça başarılı oldukları rapor edilmiştir (Basiri et al, 2011;Patel et al, 2018;Hassan and Fetouh, 2019). Bu bitki ekstraktlarının içerdiği fitokimyasalların yüksek oranda antioksidan ve antimikrobiyal aktivitelere sahip olmalarından dolayı vazo ömrünü olumlu yönde etkilediği düşünülmektedir.…”

The Effects of Some Hypericum Extracts on the Vase Life of Gerbera ÖZ Amaç: Gerbera dünyada üretimi ve ticareti yapılan en önemli kesme çiçek türlerinden biridir. Ancak petallerde solma ve boyun bükme nedeniyle vazo ömrü kısalmaktadır. Kesme çiçeklerde en önemli ticari kalite kriterlerinden biri olan vazo ömrü, vazo solüsyonuna ilave edilen koruyucu maddelerle artırılabilmektedir. İnsan sağlığına zararlı olmayan ve çevre dostu olarak bilinen bitki ekstraktları da kesme çiçeklerde hasat sonrası ömrü arttırmada alternatif olmaya aday maddelerdir. Bu çalışma ile bazı kantaron türlerinden elde edilen bitki ekstraktlarının gerbera çiçeklerinin vazo ömrü üzerine etkilerinin belirlenmesi amaçlanmıştır. Materyal ve Metot: Çalışmada bitkisel materyal olarak Gerbera jamesonii Bolus türüne ait kırmızı çiçekli ‹Yeliz› çeşidi; vazo solüsyonu olarak üç farklı kantaron türüne (H. heterophyllum, H. perforatum, H. scabrum) ait çiçeklerden elde edilmiş üç farklı dozdaki (50, 100, 150 mg/L) bitki ekstraktı ile saf su (kontrol) kullanılmıştır. Çiçeklerde; vazo ömrü, oransal taze ağırlık, günlük ve toplam vazo solüsyon alımları incelenmiştir. Bulgular: Kantaron ekstraktlarının gerbera çiçeklerinin vazo ömrünü önemli derecede etkilediği belirlenmiştir. Uygulamalar arasında en uzun vazo ömrü (14.00 gün) kontrole göre vazo ömrünü 4.00 güne kadar uzatan 100 mg/L H. perforatum ekstraktı içeren uygulamadan elde edilmiştir. Sonuç: Çalışma, kantaron türlerine ait bitki ekstraktlarının vazo ömrünü arttırmada etkili oldukları sonucuna varılmıştır.
