Turkey, being a bridge between Asia and Europe, is a critically important country owing to its ecological advantages including a wealth of herbal flora. Despite this, ornamental plant production which began in 1940, has not developed as expected. In 2003, the total value of agricultural products was 32 billion Euros. However, ornamental plant production value was 276 million Euros in Turkey. In other terms, the portion of the ornamental plants sector in the total agricultural production value was 0.9%. On the other hand, the total exports of ornamental plants amounted to US $35.6 million in 2005. This document will analyze the structural problems of Turkey's ornamental plants sector with respect to the E.U. standards and discuss regulatory implications.

Turcja będąca pomostem między Azją a Europą jest bardzo ważnym krajem z powodu swoich zalet ekologicznych, do których należy bogactwo roślin zielnych. Pomimo tego, produkcja ro ślin ozdobnych, która rozpoczęła się w 1940 roku, nie rozwija się tak dobrze, jak oczekiwano. W 2003 roku całkowita wartość produkcji rolnej osiągnęła 32 miliardy euro, z czego 276 milionów euro to wartość produkcji roślin ozdobnych. Oznacza to, że udział sektora roślin ozdobnych w całkowitej produkcji rolnej wynosi tylko 0,9%. Z drugiej strony, w 2005 roku całkowity eksport ro ślin ozdobnych wyniósł 35,6 milionów dolarów amerykańskich. Praca ta ma na celu zanalizowanie problemów strukturalnych sektora roślin ozdobnych Turcji w związku ze standardami Unii Europejskiej oraz przedyskutowanie wniosków z niej wynikających.

The frequency of applying of cut flowers to decorate graves in thirteen municipal or parish cemeteries in the city of Wrocław were estimated in years 1998-2000. In each cemetery 10 sample places with 50 graves were chosen. The research covered the species which occurred more than twice. It consisted of herbal plants and shrubs. Analysing the frequency of applying of plants, 129 taxa from 43 botanical families were estimated. The greatest number of taxa were used in Summer – 99, the next in Autumn – 61 and Spring – 50. In each cemetery, respectively, the same 20, 14 and 17 taxa were applied. In Spring the most frequently graves were decorated with: Salix caprea, Tulipa sp., Forsythia cultivars, Narcissus cultivars, Dendranthema grandiflora – spray cultivars, in Summer – Dendranthema grandiflora – spray cultivars, Gypsophilla paniculata, Callistephus chinensis, Campanula glomerata, Lilium cultivars, and in Autumn – Dendranthema grandiflora, Dendranthema grandiflora – garden cultivars, Dahlia pinata, Gladiolus cultivars, Crocosmia crocosmiflora.

Częstość stosowania kwiatów ciętych na grobach i obok nich badano w latach 1998–2000 na 13 cmentarzach Wrocławia, komunalnych i rzymskokatolickich. W tym celu na każdym cmentarzu wybrano 10 reprezentatywnych miejsc, obejmujących po 50 grobów. Uwzględniono taksony występujące częściej niż dwa razy, uznając mniejszą częstość za sporadyczną. Spisem objęto cięte rośliny zielne, w tym tzw. zieleń ciętą oraz gałązki krzewów i krzewinek. Oznaczono łącznie 129 taksonów kwiatów ciętych. Najwięcej stosowano latem – 99, następnie jesienią – 61 i wiosną – 50, w tym na każdym analizowanym obiekcie powtarzało się odpowiednio: 20, 14 i 17 taksonów. Wiosną groby na wszystkich cmentarzach najczęściej udekorowane były wierzbą iwą, odmianami tulipana, forsycją, odmianami narcyza, drobnokwiatowymi odmianami chryzantemy wielkokwiatowej i bukszpanem zawsze zielonym; latem – drobnokwiatowymi odmianami chryzantemy wielkokwiatowej, gipsówką wiechowatą, astrem chińskim, dzwonkiem skupionym, liliami i pysznogłówką ogrodową; jesienią – chryzantemą wielkokwiatową, drobnokwiatowymi (gruntowymi) odmianami chryzantemy wielkokwiatowej, dalią ogrodową, mieczykiem i krokosmią ogrodową.

In years 2005-2007 the usefulness of Allium christophii TRAUTV., A. neapolitanum CIRILLO, A. ’Purple Sensation’ and Nectaroscordum siculum (UCRIA) LINDL. was assessed for delayed culture for cut flowers, and of A.’ Ivory Queen’ as a potted plant. The bulbs were forced in the greenhouse in two years, from the first half of May (8 May 2005, 4 May 2006 and 11 May 2007) and from the first half of June (5 June 2005, 1 June 2006 and 8 June 2007). Allium ’Purple Sensation’ and N. siculum were forced only in 2007. In autumn and winter the bulbs were kept indoors at a temperature of 20°C. Then, 16 and 18 weeks before the start of forcing, the bulbs were planted and cooled indoors at 5°C and 2°C. An exception was A. neapolitanum, whose bulbs were first dry-cooled and then planted 4 weeks before transferring them to the greenhouse. On the basis of obtained results, it can be stated that the taxa useful in delayed culture for cut flowers include A. christophii and A. neapolitanum, and A. ’Ivory Queen’ as a potted plant. Cooling of the bulbs should last 18 weeks and start in the first half of May.

W latach 2005-2007 oceniano przydatność do uprawy opóźnionej na kwiat cięty Allium christophii TRAUTV., A. neapolitanum ClRILLO, A. ‘Purple Sensation’ i Nectaroscordum siculum (UCRIA) LINDL. oraz jako rośliny doniczkowe A. ‘Ivory Queen’. Cebule pędzono w szklarni w dwóch latach, od pierwszej połowy maja (8.05.2005, 4.05.2006, 11.05.2007) i od pierwszej połowy czerwca (5.06.2005, 1.06.2006, 8.06.2007). Jedynie A. ‘Purple Sensation’ i N. siculum pędzono w 2007 r. Cebule czosnków jesienią i zimą przechowywano w pomieszczeniu o temperaturze 20°C. Następnie na 16 i 18 tygodni przed rozpoczęciem pędzenia cebule zostały posadzone i chłodzone w pomieszczeniu o temperaturze 5°C i 2°C. Wyjątek stanowił A. neapolitanum, którego cebule początkowo chłodzono na sucho i sadzono na 4 tygodnie przed przeniesieniem do szklarni. Na podstawie uzyskanych wyników można stwierdzić, że do uprawy opóźnionej na kwiat cięty przydatne są A. christophii i A. neapolitanum, a jako rośliny doniczkowe A. ‘Ivory Queen’ . Chłodzenie cebul powinno trwać 18 tygodni i rozpoczynać się w pierwszej połowie maja.

The effect of benzyladenine on Astilbe × arendsii Arends flowering was determined. The cultivation of Astilbe × arendsii in an unheated plastic tunnel reduces the inflorescence yield in the first and second year of flowering as compared to the field, but increases the fresh weight and lenght of inflorescence stems.

Badano wpływ 6-benzyloadeniny na kwitnienie tawułki Arendsa ‘Amethyst’ uprawianej w nieogrzewanym tunelu foliowym i w gruncie. Benzyloadeninę zastosowano w stężeniach: 0, 100, 200 i 400 mg·dm⁻³, dolistnie, dwukrotnie w obu latach trwania doświadczenia. Uprawa w nieogrzewanym tunelu foliowym obniża plon kwiatostanów w pierwszym i drugim roku kwitnienia w porównaniu do uprawy w gruncie, ale zwiększa świeżą masę i długość pędów kwiatostanowych. BA – 200 mg·dm⁻³ zastosowana na roślinach uprawianych w gruncie zwiększa plon pędów kwiatostanowych w obu latach kwitnienia.

The study focused on the influence of benzyladenine (BA) on the flowering of Liatris spicata L.‘Alba’ cultivated for two years in an unheated plastic tunnel and in the field. Benzyladenine at a concentration of 0, 100, 200, 400 mgdm-3 was applied on the leaf twice during both years of the experiment. It was noted that cultivation of Liatris spicata L.’Alba’ in an unheated plastic tunnel leads to the growth of longer inflorescence stems with a bigger fresh weight and a larger number of primary shoots. However, in comparison with control plants, it decreases the yield of inflorescence stems in the first and second year of the plants’ flowering. It is benefi cial to apply benzyladenine at a concentration of 400 mg x dm-3 on the leaves of Liatris spicata L. ‘Alba’ cultivated in an unheated plastic tunnel, because this treatment increases the number and fresh weight of inflorescence stems as well as the number of primary shoots in the first and second year of the plants’ flowering. It is also justifi ed to apply benzyladenine at a concentration of 400 mgdm-3 on Liatris spicata L. ‘Alba’ cultivated in the field, as it leads to a greater number and fresh weight of inflorescence stems in the first and second year of flowering.

Zbadano wpływ benzyloadeniny (BA) na kwitnienie liatry kłosowej (Liatris spicata L.) ‘Alba’ uprawianej przez dwa lata w nieogrzewanym tunelu foliowym i w gruncie. Benzyloadeninę w stężeniach: 0, 100, 200, 400 mg x dm-3 zastosowano dolistnie, dwukrotnie w obu latach trwania doświadczenia. Stwierdzono, że uprawa liatry kłosowej w nieogrzewanym tunelu foliowym sprzyja wytwarzaniu dłuższych pędów kwiatostanowych, o większej świeżej masie i większej liczbie rozgałęzień I-rzędu, ale zmniejsza plon pędów kwiatostanowych w pierwszym i w drugim roku kwitnienia roślin, w porównaniu do roślin kontrolnych. Korzystne jest dolistne stosowanie benzyloadeniny w stężeniu 400 mg x dm-3 na rośliny liatry kłosowej uprawianej w nieogrzewanym tunelu foliowym, gdyż zabieg ten zwiększa liczbę i świeżą masę pędów kwiatostanowych oraz liczbę rozgałęzień I-rzędu w pierwszym i w drugim roku kwitnienia roślin. Celowe jest stosowanie benzyloadeniny w stężeniu 400 mgdm-3 na rośliny liatry kłosowej uprawianej w polu, ze względu na większą liczbę i świeżą masę pędów kwiatostanowych w pierwszym i drugim roku kwitnienia.

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.

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.

Identification of cultivars is essential both in breeding and to settle cultivar disputes. The purpose of the study has been to examine cultivar identities based on absorption spectra of plant pigments and to confirm a genetic stability with SCoT and RAPD molecular markers in new Polish lines of Chenopodium quinoa Willd. Spectral analysis of pigments extracted from plant inflorescences in quinoa gives an opportunity to confirm the cultivar identity and identification of ‘Faro’ and ‘Titicaca’ cultivars and their new lines. Spectral analysis is an effective method of confirming cultivar identity and it should be used in practice for the identification of cultivars or cultivars lines in Chenopodium quinoa Willd. Analysis of molecular markers indicated by RAPD as well as SCoT technique revealed a high genetic stability of the derivative lines of ‘Faro’ and ‘Titicaca’, while variation was detected in plants representing original cultivars: banding pattern different than predominant was present in three plants of ‘Titicaca’ (genetic distnaces from 7.5% to 55.9%) and in a single plant of ‘Faro’(genetic distance 61.2% as indicated by SCoT technique).
