Öğe The effects of pre-planting bulb storage temperatures on flower development of pot-grown narcissus(International Society for Horticultural Science, 2019) Oö Zzambak, M.E.; Zeybekoglu, E.; Alp, Ş.; Salman, A.While cut narcissus is a popular ornamental crop in Turkey, there is almost no production of pot-grown narcissus. In this study the aim was to determine suitable cultivars for pot cultivation and investigate the effects of pre-cooling treatments on growth and flowering. Bulbs (grade 13-14cm circumference) of eight cultivars were grown in pots. Before planting, three pre-planting bulb storage treatments were applied: 1) 17-20°C for 9 weeks followed by 9°C for 6 weeks; 2) ambient (fluctuating) temperatures for 9 weeks followed by 9°C for 6 weeks; 3) ambient (fluctuating) temperatures for 15 weeks (control). The treated plants were then grown under greenhouse conditions. Flower stem length, flower length, leaf length, first flowering time and flowering period were affected by the treatments. Treatment 1 gave the most favourable results: flowering was 7,6 days earlier than in the control and quality was better. Five cultivars – ‘Dutch Master’, ‘Strong Gold’, ‘Ice Follies’, ‘Golden Harvest’ and ‘Professor Einstein’ – were determined as suitable cultivars for pot plant production. © 2019 International Society for Horticultural Science.

By the planting of offshoots, dormant stumps or dormant stump pieces on the place of dead plants procedures have been adopted by the growers. These methods will be not fully successfully due to the potential wilting of newly planted offshoots, late awakening of the dormant stumps, or pieces of dormant stumps and also being in competition with the older more established neighbouring plants resulting in a heterogenic plantation in terms of growth. In this study, the potential of different planting materials for obtaining potted sprouted seedlings, which were thought to be more efficient to regenerate the old artichoke plantations during the vegetation period, was investigated. The study was held in a grower field in Seferihisar town of Izmir in 2011. Two artichoke cultivars ('Sakiz' and 'Bayrampasa') were used. The influence of (i) three different pot volumes, (ii) five different dormant stump pieces (in terms of sizes and/or typologies used) and (iii) the humic acid application before rooting were assessed. The investigated criteria were: 1) percentage of the rooted plants with respect to the number of vegetative materials planted in different volumes of pots and treated with humic acid or not; 2) quality of seedlings propagated by these techniques; 3) survival percentage of these one month old seedlings and dormant stump pieces after their plantation in the field. While no statistical effect determined from humic acid applications was observed, higher pot and stump sizes gave higher results. Different results were also obtained from different stump types in terms of rooting ratios and some seedling quality. With this study, satisfactory rates were obtained in terms of produced seedling ratios (86.9-100%) and their survival performance in the field (95-100%).Öğe Potted Artichoke Seedling Propagation by Using Different Vegetative Materials and Techniques(Int Soc Horticultural Science, 2013) Zeybekoglu, E.; Ugur, A.; Pagnotta, MAIn Turkey studies are made to overcome/repair the sparseness of perennial artichoke plantations.

E.; Zeybekoglu, E.; Tuncay, O.; Baser, S.; Haspolat, G.; Olgun, A.; Tuzel, Y; Oztekin, GB; Meric, MKTurkey has great potential in cut flower production. Export is the main activity to accelerate the production. Domestic consumption has also great importance in this improvement. Therefore, it is important to know consumer preferences. In order to determine consumer's trends and expectations, a public survey was conducted in different regions of Turkey between the years 2005 and 2006, with 1141 interviewees. The survey group consisted of 427 females and 714 males in different age and income groups. Fourty percent of the interviewees were in the medium and low income group (385-770 USD month(-1)). Fifty eight percent of the consumers mentioned that they bought flowers only on special days and their purchasing frequency did not depend on cut flower prices. Only 31% of the consumers stated that they bought flowers for themselves. Flowers were the most preferred gifts (39.7%) compared to other choices. The priorities of the consumers in flower purchase were freshness (21.7%), colour (17.8%), other quality parameters (17.6%), scent (14.3%) and price (10.3%). Rose with 70.3%, narcissus with 8% and carnation with 6% are the cut flower species which are mostly preferred. Red, white and yellow are the primary colour choices of the consumers.
