    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:
    Thrips nigropilosus Uzel is a polyphagous species occurring mainly in temperate climates. Its life cycle depends on photoperiodic and temperature conditions. T. nigropilosus feeds on different plant species, but it is considered one of the most serious pests of pyrethrum plants causing serious economic problems. However, several additional agricultural host plants have been affected by T. nigropilosus, including spearmint, cucumber, and lettuce, indicating that this insect can significantly widen its habitats and occurs especially frequently in greenhouses. We report that T. nigropilosus massively attacked Mentha × piperita L. cultivated in greenhouses in central Poland and destroyed the entire mint crops within a short time. The study provided insight into the harmful effect of the thrips and showed that the length of the thrips developmental cycle was reduced with temperature increases from 18 to 26.6°C. The lower threshold temperatures were 13.7, 10.2, 5.0, and 10.1 for eggs, larvae, pupae, and total development, respectively, and the thermal constant for the same developmental stages was 65.9, 90, 132.5, and 284.9-degree days. Both parameters were estimated by linear regression analysis. During our experiment, T. nigropilosus developed by thelytokous parthenogenesis. The morphological and anatomical changes in damaged plants were associated with the fact that the insect began feeding on the lower lamina surface close to the leaf midribs, but no damage to vascular bundles and glandular cells was observed.

    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:
    The interaction between foliar treatment with 100 mg∙dm–3 of both gibberellic acid 4+7 (GA4+7) and benzyladenine (BA) and vase solution containing 3% sucrose was analysed in cut Lilium ‘Alma Ata’. GA4+7+BA considerably delayed leaf senescence, suppressed anthocyanin accumulation in the leaves of plants held in the sucrose solution and improved the average longevity of the flowers and the vase life of the stems. Sucrose in the vase solution strongly reduced the abscission of leaves and contributed to the enlargement of the top flower. The number of significant interactions between the treatments indicated that the investigated factors acted dependently mainly on flower quality, while their action on leaf quality was mostly independent. Results show that combined treatment with growth regulators and sucrose may considerably increase postharvest quality of cut Lilium ‘Alma Ata’.

    Opis:
    The study of the bionomy of privet sawfly (Macrophya punctumalbum (L.), a pest of park plants in the city of Poznań, was conducted during three vegetation seasons in the years 1981–1983, at the insectarium of the Department of Entomology at Agricultural University in Poznań. The aim of the study was to define the longevity and fecundity of imagines, larvae development of the species and the level of parasitizing the eggs of the privet sawfly by parasitoids of the Chalcidoidea superfamily. The sawfly occurred in the last ten days of May. The females lived from 4 to 36 days, most often quite short (73.3%), from 7 to 14 days. After reaching the stage of sexual maturity, which lasted mostly 8–9 days, they started laying eggs. The fecundity of females fluctuated between 1 and 122 eggs. The mean female fecundity was 52 eggs. It was found that the larvae of sawfly went through 5 instar stages. The parasitoids of the Chalcidoidea superfamily decreased the abundance of the sawfly at the egg stage from 0.47% to 8.65%. Those were Anaphes cultripennis Debauche (Mymaridae) and Trichogramma sp. (Trichogrammatidae).
    Badania nad bionomią brosznicy jesionówki (Macrophya punctumalbum (L.), szkodnika roślin parkowych miasta Poznania, prowadzono przez trzy sezony wegetacyjne, w latach 1981–1983, w insektarium Katedry Entomologii Akademii Rolniczej w Poznaniu. Celem badań było określenie długości życia imaginalnego, płodności i rozwoju larwalnego tego gatunku oraz stopnia spasożytowania jaj brosznicy przez parazytoidy z nadrodziny Chalcidoidea. Błonkówki pojawiały się w III dekadzie maja. Samice żyły od 4 do 36 dni, przy czym najczęciej krótko (73,3%), od 7 do 14 dni. Po uzyskaniu dojrzałości płciowej, trwającej przeważnie 8–9 dni, przystępowały do składania jaj. Płodność samic wahała się w granicach od 1 do 122 jaj. Średnia płodność samic wyniosła 52 jaja. Ustalono, że larwy brosznicy przechodziły przez 5 stadiów rozwojowych. Parazytoidy z nadrodziny Chalcidoidea obniżyły liczebność brosznicy w stadium jaja w granicach od 0,47% do 8,65%. Były nimi Anaphes cultripennis Debauche (Mymaridae) i Trichogramma sp. (Trichogrammatidae).

    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:
    Early maturing peach (Prunus persica) cultivars can fetch good market value but face a lot of post-harvest problems that lead to the post-harvest losses. The 1-methylcyclopropene (1-MCP) can provide new insights into plant ethylene responses and extend the shelf life and quality of fruits. Therefore, fruits of peach cultivar ‘Early Grand’ were dipped in various concentrations of 1-MCP (0, 0.3, 0.6 and 0.9 µg l–1), stored for 40 days at 8 ±2°C with 50% relative humidity and analyzed the fruits for physicochemical attributes at 10 days interval. The highest concentration of 1-MCP at 0.9 µg l–1 significantly improved the activity of antioxidants, catalase, free radical scavenging assay and total phenols. However, the peach fruits treated with 1MCP at 0.6 µgL–1 was effective in retaining the ascorbic acid, lowering the weight loss and fruit decay. Therefore, peach fruits can be treated with 1-MCP (0.6 µg l–1) solution for prolonging its shelf life up to 40 days under low temperature.

    Opis:
    Control fruits and fruits subjected to 1-MCP application were placed in cold storage at 2°C, 90% r.h. for 18 weeks. The susceptibility of ten apple cultivars: ‘Beni Shogun’, ‘Braeburn Hillwell’, ‘Elise’, ‘Gloster’, ‘Golden Delicious’, ‘Idared’, ‘Jonagold Decosta’, ‘Ligol’, ‘Mutsu’ and ‘Šampion’ was tested using an impact test to obtain bruising of fruits. The analyses were performed on fruits immediately after harvest and four times after different period of cold storage (9 and 18 weeks) and shelf-life (7 days). The following analysis and characteristics of apples were determined: soluble solids content, dry matter content, acidity, fruit mass and size, and firmness. Impact test was carried out by dropping a glass ball with a mass of 25.68 g from height of 40 cm, due to which kinetic energy value of 0.1 J was obtained. Slight differences in acidity and soluble solid content were observed. On the other hand, stress noticed at firmness test was significantly higher for fruits treated with 1-MCP. It was also observed that firmness decreases after the shelf-life and after storage of fruit at room temperature. The ‘Beni Shogun’ apples fruits stored for 9 weeks are most susceptible to bruising (volume = 438.26 mm3). After cold storage, less susceptible cultivar was ‘Szampion’, for which the volume of fruit bruise was 145.62 mm3 only. After 9 weeks of cold storage, for most cultivars, there was no significant differences in bruise volume; however, the shelf-life had significant influence by differing the cultivars, and for all studied cultivars, the bruise volume was lower.

    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’.

    Opis:
    During the cold storage of sweet cherry, severe losses can occur due to the water loss, phytopathogenic fungi and physiological disorders. The aim of this research was to assess the effects of treatments with NAA (α-naphthaleneacetic acid), BA (6-benzyladenine), and GA3 (gibberellic acid) on fruit quality at harvest and after 21 days of storage under two regimes, including 0°C, RH (relative humidity) 90% and 3°C, RH 70%, and after additional shelf life exposure. Sweet cherry cultivars – ‘Summit’, ‘Kordia’ and ‘Regina’ – were treated with bioregulators at the end of flowering. NAA significantly increased the fruit weight at harvest compared to the control in all cultivars assessed. BA stimulated the fruit growth in ‘Kordia’ and ‘Regina’, while it was ineffective in ‘Summit’. GA3 caused significant increase in fruit weight by 8.3% in ‘Kordia’ only. Moreover, BA and GA3 induced a higher firmness of fruits at harvest. Weight loss of fruits during storage at 0°C, RH 90%, was increased with NAA and reduced with GA3 in ‘Regina’ only. BA and GA3 reduced the weight loss of sweet cherry fruits stored at 3°C, RH 70%. Bioregulator treatments increased TA (titratable acidity) in fruits at harvest, while the effects on TA during storage were variable depending on the cultivar. ‘Summit’ had the highest sensitivity to storage fruit rot. BA and GA3 decreased the disease occurrence on fruits stored at 0°C in ‘Summit’ and ‘Kordia’.
