    Opis:
    The response of cut Amaranthus tricolor foliage to continuous treatment with 200 mg·l-1 8-hydroxyquinoline citrate (8-HQC) or 2, 4 and 6% ethanol was investigated. Application of ethanol and HQC enhanced the vase-life and final fresh weight. The best quality cut Amaranthus tricolor foliage were obtained when the stems held in 4% ethanol. These are the first published results that indicate that ethanol positively improved the postharvest quality of cut Amaranthus tricolor foliage.

    Opis:
    This research investigated the effect of different concentrations of sodium nitroprusside (SNP, a donor of nitric oxide) on the longevity of cut giant chincherinchee (Ornithogalum saundersiae) inflorescences. Postharvest quality of inflorescences was positively affected by SNP treatment. Application of SNP enhanced the vase-life, final fresh weight and diameter of inflorescences. The best quality inflorescences were obtained when the stems held in 100 µmol SNP. These are the first published results that indicate that nitric oxide positively improved the longevity and quality of cut O. saundersiae 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:
    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:
    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.
