Opis:
This study was done using three nitrogenous compounds to evaluate their effects on postharvest characteristics of chrysanthemum (Chrysanthemum indicum) cut flowers. The study consisted of three separate and parallel experiments, in which ammonium sulfate, calcium nitrate and potassium nitrate were used in different concentrations of zero, 50, 100, 200 and 500 mg dm ‒3 N for pretreatment of stems for 6 hour before transferring to holding d-water solution. The results showed that petal ion leakage and leaf SPAD values were increased by increasing ammonium sulfate, but not calcium or potassium nitrate. Petal carotenoids were increased by pretreatment of ammonium sulfate and potassium nitrate. There was constant increase in water uptake by increasing the levels of calcium nitrate and potassium nitrate, while ammonium sulfate at high concentrations (200 and 500 mg dm ‒3 N) resulted in significant less water uptake compared to control. Ammonium sulfate in 50 and 100 mg dm ‒3 increased shelf life of pretreated stems, but higher concentrations significantly reduced cut flowers shelf life. Increasing concentrations of calcium nitrate and particularly potassium nitrate have led to prolongation of flower shelf life to 12 days compared to 6 days of control. The results indicate that pretreatment of chrysanthemum cut flowers with ammonium sulfate in rather low concentrations or with moderate to high concentrations of calcium nitrate or potassium nitrate can significantly improve shelf life and postharvest flower qualities.

Opis:
Garden perennials are a source of floristry material produced in field or under covers. A perennial producing long, leafy shoots, which in flower arrangements might successfully substitute fern or palm leaves, is Polygonatum multiflorum. The variety characterizing with decorative white margined leaves is ‘Variegatum’. To improve their quality, the growth stimulator Actisil Hydro Plus, which contains 0.6% of active silicon in a form of orthosilicic acid was applied. The aim of the conducted experiment was to estimate the influence of silicon and a place of cultivation (tunnel and open field) on post-harvest quality determined with morphological features, vase life longevity and mechanical properties of Polygonatum multiflorum (L.) All. ‘Variegatum’ stems. The plants were sprayed with water solutions of Actisil in concentrations: 0.2%, 0.3%, and 0.4%, six times during the growing season in weekly intervals, starting from the first decade of May, always in the morning. It was stated that cultivation of Polygonatum in the unheated foil tunnel increases quality of shoots for cut greenery, determined with morphological features and post-harvest longevity. Cultivation of Polygonatum in a foil tunnel and spraying plants with Actisil in concentrations of 0.3 or 0.4% is advantageous due to possibility to increase a number of shoots from 20% to over 31%, their length from 9% to 11% and fresh weight from 52% to 71%, in comparison to control plants. It is advised to treat plants cultivated in a tunnel, with Actisil in concentration of 0.4% as it improved shoots quality evaluated with their diameter and lower leaves blade area. Spraying plants with Actisil in concentrations of 0.2–0.4% in the tunnel and 0.2% in field prolongs post-harvest shoots longevity by 3–4 days. Plants cultivated in the tunnel characterize with higher strength of shoots determined with higher maximum force causing permanent damage and lower stem deflection than plants cultivated in field. Plants grown in a tunnel and sprayed with Actisil in concentrations of 0.4% characterized with the strongest shoots after 14 days of storage, however a similar effect was observed with the concentration of 0.3% and in case of plants cultivated in field and sprayed with 0.4% of Actisil.

Opis:
Tuberose (Polianthes tuberosa L.) is an ornamental bulbous plant and a famous cut flower in tropical and subtropical regions. Post-harvest senescence of the cut flowers is the main factor limiting the marketability of most of these species including tuberose. From the perspective of metabolic changes, senescence happens as the result of oxidative processes induced by active oxygen species production. Gamma-aminobutyric acid (GABA) and salicylic acid (SA) are compounds with some functions in the post-harvest physiology of some plants. The present study focused on the effect of GABA and SA on vase life and some post-harvest traits of cut tuberose flowers. The plants were sprayed with GABA (5, 10, or 15 mg L–1) and SA (50, 100, or 150 mg L–1) at three stages during growth and before harvest in a greenhouse (30, 45, and 60 days after the planting of the bulbs) and were observed after harvest until senescence. Results showed that GABA and SA positively affected the vase life, water uptake, fresh weight, ion leakage, total dissolved solids, chlorophyll, protein, and catalase, peroxidase, and ascorbate peroxidase enzymatic activity. They postponed senescence. The highest and lowest vase lives were observed in plants treated with 10 mg L–1 GABA (11 days) and control (distilled water) (7 days), respectively. It was found that the treatment of tuberose with GABA and SA during growth can improve its post-harvest quality. However, it is recommended to conduct further studies on them.

Opis:
Floral exchange markets drive steadily growing interest in ornamental plants sold as cut flowers. Unfortunately, vase life of some of these flowers remains unsatisfactory. Their ornamental value depends on their longevity and number of flowers, as well as overall appearance of the stem during its vase life. Our study determined the effects of storage conditions and Floralife flower food on vase life and ornamental value of Crocosmia ×crocosmiiflora ‘Lucifer’. Crocosmia inflorescences can be attractive cut flowers after meeting some basic requirements. Cutting the branched shoots when the first flower in the main inflorescence was fully open, the second was opening and the subsequent buds showed visible color allowed for maintaining their decorative value for an average of 18.8 days, irrespective of storage conditions and flower food. Vase life and ornamental value depend on storage conditions. Keeping the inflorescences in a semi-lit room (16.8 µmol∙m–2∙s–1), at 18–20°C, and relative humidity of 55–60% or in darkness, at 14–16°C, and relative humidity of 60–70% reduced the number of developed flowers, inflorescence weight and the amount of absorbed solution, and also declined inflorescence vase life. Application of Floralife 200 and Floralife 300 flower food increases the vase life by respectively 7.9 and 8.2 days vs. water, and improves the quality of stored inflorescences.

Opis:
Three cultivars of Hyacinthus orientalis L. were forced in pots under artificial light using fluorescent lamps which emitted white, blue, green, yellow and red light. Daily light dose was 0.54 mol·m⁻² (25 μmol·m⁻²·s⁻¹ × 6 h). Significant effect of light colour on postharvest longevity and quality of plants was observed. The post-harvest longevity of hyacinths depends, among others, on the length of the flowering period and it is the longest after the application of white and blue light colour. Red light decreased flower life and deteriorated the ornamental value. The rigidity of inflorescence shoots depended on the cultivar, but in all flowers, it was significantly lower than it is recommended in market turnover for flowering plants grown in pots. It also refers to leaves, whose elongation is the greatest under lamps with red colour. In the ‘Fondant’ cultivar, elongation caused a maximal flabbiness of inflorescence shoots and leaves.
Cebule trzech odmian hiacyntów pędzono przy sztucznym świetle, pod lampami fluorescencyjnymi typu TLD 36W, emitującymi światło białe, niebieskie, zielone, żółte i czerwone. Dobowa ilość światła wynosiła 0.54 mol·m⁻² (25 μmol·m⁻²·s⁻¹ × 6 h). Trwałość pozbiorcza hiacyntów zależała m.in. od długości okresu kwitnienia, a ten był najdłuższy po zastosowaniu białej i niebieskiej barwy światła. Światło czerwone obniżało trwałość kwiatów i pogarszało wartość ozdobną roślin. Sztywność pędów kwiatostanowych zależała od odmiany, ale u wszystkich była niższa od pożądanej. Dotyczy to również liści, których elongacja była największa pod lampami o barwie czerwonej. U odmiany ‘Fondant’ liście były bardzo wiotkie.

Opis:
Bio-stimulants are in excessive demand for the sustainable production of floriculture crops. The current investigation was designed to find out the effect of naturally occurring growth stimulant moringa leaf extract (MLE) on the growth, flowering, post-harvest life and corm production of two gladiolus cultivars (cvs.) ‘Rose Supreme’ and ‘White Prosperity’. The research trial was laid out in the factorial arrangement under randomized complete block design. Corms were grown in the open field under local climatic conditions of Faisalabad, Pakistan. Potential of exogenously applied (MLE; 30 times diluted) was evaluated. Treatments including spraying MLE at 3 leaves, 5 leaves, floral bud stage, one combination of these three stages relative to control with no foliar application. Application of natural bio-stimulant produced maximum height in both cvs. against T4. Both cvs. gave maximum stalk length in response to T4. The number of florets spike–1 found the maximum (13) in T1 compared to control T0 which yield (9) florets. Maximum vase life in sucrose solution (13.33 days) was exhibited by T1 for both cvs. while minimum (10 days) in T0. In cultivar comparison earlier spike emergence was observed in ‘White Prosperity’. In ‘Rose Supreme’ maximum corm weight was attained in response to T3 (43.43 g) while minimum (30.33 g) in T0.‘White Prosperity’ produced maximum weight (40.33 g) against T4 whereas minimum by control. The cultivar mean comparison showed the superiority of cormel diameter in ‘Rose Supreme’ (10.93 mm) than ‘White Prosperity’ (9.13 mm). In treatment comparison, T4 produced maximum diameter (12.04 mm) in ‘Rose Supreme’ moreover, T2 induced maximum (9.57 mm) diameter in ‘White Prosperity’.
