Investigatións on in vitro rooting and acclimatization of sour cherry cv. heimanns rubinweichsel

Sour cherry shootlets obtained via in vitro propagation were rooted in half concentrated MS medium containing 5.5; 11.0; 16.5 and 22.0 µM IAA, IBA and NAA. It was noticed that they rooted well in those levels, however, with regard root color, shape, thickness and callus production rate, IAA has proven itself better than the others. Perlitte, peat, soil-sand-manure mixture; pomza, while later development of the plantlets were better in peat and sand-manure mixture

The effects of ca application on some stress parameters of limonium sinuatum under salinity conditions in the greenhouse growing

Araştırma, örtü altı tuzlu koşullarda yetiştirilen Limonium sinuatum bitkisinde bazı stres parametreleri (yaprak oransal nem içeriği, klorofil, karotenoid, prolin ve lipid peroksidaz) üzerine kalsiyumun etkilerini belirlemek amacıyla yürütülmüştür. Örtü altı tuzlu toprak koşullarında Limonium sinuatum yetiştiriciliğinde 20 mM ve 30 mM Ca'1 kalsiyum uygulamalarının tuzun olumsuz etkisini azalttığı saptanmıştır. Tuzlu ortamda kalsiyum uygulamaları yaprak oransal nem ve karotenoid içeriklerinde tuzun olumsuz etkisini hafifletmiştir. Klorofil a, klorofil b ve toplam klorofil değerleri 20 mM Ca*'! kalsiyum dozunda % 1 düzeyinde olumlu etki göstermiştir. Prolin değerlerine bakıldığında ise kalsiyumun en yüksek dozu olan 30 mM Ca*2 uygulaması prolin içeriğini % 60'a varan değerde azaltmıştır. Aynı durum MDA içeriği açısından da gözlemlenmiş ve MDA içeriklerinde önemli düzeyde gerilemeler saptanmıştır. Çiçek sayısı, çiçek sapı uzunluğu ve kalınlığı değerlerine bakıldığında ise çok önemli olmasa da 20 mM Ca'2 kalsiyum dozu uygulamasının olumlu etkileri belirlenmiştir.The research was conducted to determine the effects of calcium on some stress parameters (i.e. leaf relaive water content, chlorophyll, carotenoid, proline and lipid peroxidase) of Limonium sinuatum plant, grown under saline conditions. 20 mM and 30 mM Ca*3 calcium applications reduce the negative impact of salt on Limonium sinuatum cultivation under saline soil greenhouse conditions. Under saline conditons, calcium applications decreased the negative effect of the salt on the leaf relative content and carotenoid. Chlorophyll a, chlorophyll b, and total chlorophyll values have shown positive impact at the dosage of 1 %. The highest dose of calcium, 30 mM Ca*2 application, reduced the proline content up to 60 % when the proline values are considered. The similar situation was also observed in terms of MDA content and significant decreases are identified in MDA contents. Although the significant difference is not important, 20 mM Ca*2 doses of calcium application has positive effects considering the number of flowers, the length of flower stem and the thickness of flower stem

Effects of different storage methods and periods on vase life of cut narcissus (Narcissus tazetta L. ‘Karaburun’)

Improving storage performance of cut flowers is particularly useful for flowers that are short-lived, and whose display period in the field is brief. Here we report on factors affecting postharvest performance of Narcissus tazetta L. ‘Karaburun’, which is a field-grown narcissus in Turkey. A factorial experiment was performed, in which the cut narcissi were held dry in modified atmosphere packaging (MAP) or wrapped paper at 0±0.5°C for 1, 2, 3, 4, 5 or 6 weeks, and were pulsed with 0.25 mM silver thiosulfate (STS) or distilled water (control) either before or after storage. Vase life of 7 days was reduced with increasing storage duration. The degree of the decrease in vase life depended on the type of storage treatment imposed. At 5 weeks of storage, wrapped paper was as good as MAP for maintaining vase life (4.7-5.6 days), when a pre-storage pulsing treatment was applied. However, at 6 weeks of storage, the MAP-stored flowers had a better vase life (5.3 days) than those stored in paper (4 days). The vase life of the 6-week paper-stored flowers was even less (2.1 days), when the pulsing treatment was applied after storage. By contrast, at 6 weeks of storage, the vase life of the MAP-stored flowers was the same (4.9-5 days), regardless of the time of application of the pulsing treatment pre- or post-storage. In conclusion, the best treatment for N. tazetta L. ‘Karaburun’ was MAP storage, combined with STS pulsing, applied either pre- or post-storage. © 2019 International Society for Horticultural Science.

Remarks using the sem method species seeds of Gentiana occurring in turkey [Observações utilizando o método SEM de sementes de espécies de gentiana ocorrentes na Turquia]

Seeds of eleven perennial Gentiana collected from Turkey were analyzed using the SEM method. Other species excluding G. septemfida, G. boissieri, G. gelida were studied for the first time. They were identified and compared in terms of seed characteristics and surface ornamentations. Major characteristics including the outer periclinal walls of testa, sculpting of inner periclinal walls, seed shape, seed and testa cell, wing cell size, thickness of testa wall and seed shape have been proposed for Turkey Gentiana. They are divided into different types, such as no wing, chalazal wing, incomplete discoid wing, complete discoid wing according to the outer periclinal walls of testa. Considering primary sculpting of seeds, irregularly striate and shallowly reticulate type is observed. Anticlinal walls of G. olivieri, G. boissieri and G. gelida are curved, while others are straight. G. lutea has the largest mean seed (4.20 x 4.40 mm), while G. cruciata (0.67 x 0.60 mm) and G. olivieri have the smallest mean seeds (0.67 x 0.67 mm). Seed micromorphology can be used together with morphological character to form classifications in studied specimens for Gentiana genus. © 2017, Sociedade Brasileira da Ciencia das Plantas Daninha.

A survey on cut flower preferences and expectations

Turkey 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
