“…Increased solution uptake of flowers may be justified by the antimicrobial activity of BA which prevents vascular blockage by inhibiting microbial growth and improves hydraulic conductivity. Moreover, decreased microbial growth due to the application of BA has also been reported in Tuberose, Lisianthus, cut rose and Gladiolus (Khattab et al, 2017).…”

“…These compounds are not only expensive, but also pose certain toxicological risks (Serrano et al, 2001). Boric acid (BA) may therefore be an effective substitute and a strong competitor to these ethylene antagonists in cut flower industry due to its biodegradable, inexpensive and non-toxic nature (Serrano et al, 2001;Khattab et al, 2017). During climacteric respiration, the activity of 1-aminocyclopropane-1-carboxylic acid synthase (ACC synthase) and ACC oxidase increase, which convert S-adenosylmethionine (SAM) to ACC and ACC to ethylene, respectively (Sadka et al, 2019).…”

In the floriculture industry, postharvest senescence is one of the glaring challenges restricting the marketability of cut flowers. Hence, maintaining good quality of cut flowers and extending flower longevity are considered to be the most crucial factors in the cut flower trade. Therefore, to gain better understanding of the specific physiological and biochemical aspects of petal senescence we conducted an experiment to evaluate the efficacy of Boric acid (BA) on flower longevity in excised flowers of Digitalis purpurea L. Isolated buds were harvested at stage IV i.e, 1 day before anthesis and divided into 5 sets, with one set of buds held in distilled water (DW) designated as control. The other 4 sets were supplemented with 24h pulse treatment of different concentrations of BA viz., 50, 100, 150 and 200 µM. The application of BA at 150 µM concentration was found to be most effective in increasing flower longevity by about 4 days as compared to control. The enhanced longevity coincided with higher values of floral diameter, fresh mass, dry mass and solution uptake. Flowers with delayed senescence also retained higher soluble proteins, sugars and phenols in addition to lower bacterial density compared to control. Moreover, this ameliorated flower longevity has also been shown to be positively associated with increased activities of various antioxidant enzymes viz., superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) and reduced activity of lipoxygenase (LOX).

Bu çalışmada hasat sonrası farklı dozlarda sistein, arjinin ve salisilik asit uygulamalarının kesme glayöl çiçeklerinin vazo ömrü ve çiçek kalitesi üzerine etkileri araştırılmıştır. Bu amaçla cam serada kontrollü şartlarda yetiştirilen glayöl çiçekleri başaktaki ilk kandil renklendikten sonra hasat edilmiş ve 0,5, 1 ve 2 mM sistein (S); 0,5, 1 ve 2 mM arjinin (A) veya 0,5, 1 ve 2 mM salisilik asit (SA) içeren vazo çözeltilerine yerleştirilerek, 12 saat ışık 12 saat karanlık şartlarında bekletilmiştir. Bu süreçte çiçeklerde, yaş ağırlık, çözelti alımı, açan kandil sayısı, kandil boyu, kandil çapı, renk, klorofil SPAD, vazo ömrü ölçüm ve analizleri yapılmıştır. Çalışma sonucunda 1 mM S ve A ile 2 mM SA uygulamaları çiçeklerin yaş ağırlığını arttırmıştır. 1 mM S ve A uygulamaları çiçeklerin çözelti alımını da arttırarak kandil boyutunu arttırmıştır. Tüm SA uygulamaları çiçeklerin beyazlık indeksi değerlerini yükseltmiştir. Çiçeklerin maksimum vazo ömrü ise 2 mM Auygulamasında 18 gün olarak gerçekleşirken 2 mM S ve 1 ve 2 mM SA uygulamalarında 17 güne ulaşmıştır.
