A Comparison of Management Planning Principles of Wetland Ecosystem (The Delta of Bendimahi) and Mountain Ecosystem (Mountain of Ispiriz) in the Van Lake Basin/Turkey
(2013) Durmuş, A.; Alp, Ş.; Adizel, Ö.; Ünal, M.; Karabacak, O.; Demirci, E.Y.; Berber, Ş.
Van Lake Basin which is an important and different part of East Anatolia Region possesses important biological richness due to its geological, climatic, geographical and topographical varieties. In the region, Van Lake which is located between high mountains has led to the formation of a different climate which has resulted in different vegetation and formation of important wetlands. In the basin lies Ispiriz Mountain which is one of the important natural fields and Delta of Bendimahi which is an important part of the basin. Although the flora of Ispiriz Mountain has not been thoroughly studied, 35 of the plants which have been recorded from the area are classified as endemic, whilst 50 of them have been classified as rare plants. 15 of endemic plants have been collected from Ispriz Mountain and introduced to the world. 9 of these plants are endemic plants which have been recorded from a narrow area of Ispiriz Mountain. In the Delta of Bendimahi, there are 188 bird species. 68 of these birds are local, 80 of them migrant, 20 of them winter visitor, 15 of them transit migrant and 2 of them are determined to be coincidental. In this study, together with the socio-economic structure of Delta of Bendimahi which is wetland ecosystem and Mountain of Ispiriz which is mountain ecosystem, the existing relations and problems between natural resources have been determined. According to the gathered information, basic principles of management planning of both regions have been determined. In the presentation, the characteristics of both regions and similarities and differences between the two regions would be touched upon in terms of management of natural resources. It has been determined that the security and economical problems of the region have caused different difficulties in terms of studies which have aimed to determine natural resources in both ecosystems.

(Centenary University, 2019) Sönmez, F.; Alp, Ş.
This study was conducted on the YYU campus area as a field survey, according to the randomized block experimental design carried out in three replicated. The yellow and orange marigold species with humic acids (HA0;0 kg HA da-1, HA1;10 kg HA da-1, HA2;20 kg HA da-1, HA3;40 kg HA da-1) were used. At the end of the experiment, the soil samples taken from the field of study were analyzed organic matter, soil reactions, total salt content, lime content, nitrogen, phosphorus, potassium, calcium, magnesium, natrium, iron, manganese, zinc, copper, cadmium, nickel and lead contents. The increased humic acid applications have influenced pH (P<0.01), lime (P<0.01), organic matter (P<0.05) with phosphorus (P<0.01), iron (P<0.05), zinc (P<0.05) and nickel (P<0.01) contents. The effect variety (V) has been determined on the available of soil iron (P<0.01), zinc (P<0.01), cadmium (P<0.01), nickel (P<0.01), and lead (P<0.01) contents. The interaction of only affected the nickel (P<0.01) and zinc (P<0.01) contents. As a result, humic acid applications have an important and positive effect on many properties of soil. © 2019, Centenary University. All rights reserved.
Effects of Different Storage Methods and Periods on Vase Life of Cut Narcissus (Narcissus Tazetta L. ‘karaburun’)
(International Society for Horticultural Science, 2019) Zeybekoğlu, E.; Salman, A.; Alp, Ş.; Özzambak, M.E.
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.

The Effects of Different Warm Stratification Periods on the Seed Germination of Some Rosa Taxa
(Academic Journals, 2009) Alp, Ş.; Çelik, F.; Türkoǧlu, N.; Karagöz, S.
In this study, the effects of different warm stratification periods on the seed germination of some Rosa species such as Rosa heckellana ssp. vanheurckiana, Rosa canina, Rosa pulverelanta and Rosa dumalis naturally grown in the Van region were investigated. In 2007, seeds of these species were kept at 25° C warm stratification for 10, 11 and 12 weeks, and then transferred to 5° C for cold stratification till the initiation of germination. Germination response to treatments of R. heckellana ssp. vanheurckiana seeds was different compared to the other species. The seeds of R. heckellana ssp. vanheurckiana germinated in a short time (when they kept in warm stratification followed by cold stratification between 1 - 3 weeks). The seeds of the other species required 5 months of cold stratification after warm stratification to overcome seed dormancy. The overall germination percentage were 18.80% in R. canina, 13.80% in R. pulverelanta and 13.53% in R. dumalis at 25° C of warm stratification followed by 5° C cold stratification. We determined that for these three taxa, the most appropriate method of stratification was 11 week warm stratification followed by cold stratification. © 2009 Academic Journals.

(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.

Evaluation of Median Lethal Dose and Analgesic Activity of Foeniculum Vulgare Miller Essential Oil
(2006) Özbek, H.; Taş, A.; Özgökçe, F.; Selçuk, N.; Alp, Ş.; Karagöz, S.
Gas-chromatographic analysis, analgesic effect and median lethal dose (LD50) of Foeniculum vulgare Essential Oil (FEO) extract were investigated in mice. In all the experiments mice were tested twice, 30 min before drug administration in the baseline latency determinated and 30, 90 and 150 min after drug administration by tail-flick device. Aspirin (150 mg kg-1, peroral) and Morphine hydroclorure (10 mg kg-1 subcutan) were used as reference drugs. Only isotonic saline solution (0.2 mL, intraperitoneal) was given to the control group. 0.25 and 0.50 mL kg-1 FEO extract were given intra peritoneally to FEO groups. LD50 of the FEO was determined as 1.038 mL kg-1. At the 150th min of the study it is determined that all of the study groups (except Morphine group) had significantly analgesic effect when compared with control group and there was no difference between Aspirin and FEO groups. It was concluded that FEO had statistically significant and same analgesic effect with Aspirin showed at the 150th min of the study. © 2006 Asian Network for Scientific Information.
Identification of Genetic Variations on Fritillaria Imperialis L. Genotypes Collected From Van Lake Basin by Ipbs-Retrotranspozon Markers
(Centenary University, 2020) Koçak, M.; Karataş, M.D.; Alp, Ş.; Baloch, F.S.; Yildiz, M.
Fritillaria imperialis L. naturally grows in Turkey and it is used as an ornamental plant. This species harbored plentiful genetic variation for various morphological traits in its natural habitat. In this study, 19 different iPBS-Retrotransposon primers were used to identify genetic variation among 74 F. imperialis genotypes collected around Van lake basin. 19 primers amplified 94 bands, 100% polymorphism. The average number of bands per primer was 4.94 and the average polymorphism information content (PIC) was 0.58. Maximum number of polymorphic bands were 10 while the minimum number of polymorphic bands were 2. The mean effective number of alleles, Shannon information index and the gene diversity were 1.50, 0.47, and 0.30 respectively. The results reflected that genetic variations of F. imperialis genotypes collected from Van lake basin were significant. This is the first report identifying the genetic variations of F. imperialis genotypes by iPBS-Retrotransposon primers, and it proved that iPBS-Retrotransposon marker system could be applied successfully in F. imperialis for genetics and genomic studies. The data obtained from this study will provide preliminary information for future F. imperialis breeding activities. © 2020, Centenary University. All rights reserved.
Performance Of Different Narcissus Cultivars İn Izmir Ecological Conditions
(International Society for Horticultural Science, 2019) Salman, A.; Zeybekoğlu, E.; Alp, Ş.; Özzambak, M.E.; Wallace, M.Y.
Commercial narcissus production in Turkey is mostly carried out in Izmir, Mersin, Adana and Samsun provinces and predominantly favours the multi-headed tazetta cultivars. On the other hand, the Netherlands and Great Britain, as the leading narcissus producing countries, especially breed and export a wide range of trumpet, large-cut, small-cup and double cultivars which demonstrate full adaptation to colder climates. In this research, realised in an open field belonging to Ege University’s Bayindir Vocational Training School, cool climate narcissus cultivars were examined in terms of their floral quality in Mediterranean ecological conditions. For this purpose, 22 different Narcissus cultivars were scrutinized through a set of visual criteria for their sprouting and flowering time, flowering duration, stem height and width together with the amount and diameter of their flowers. The cultivars demonstrated rather different outcomes. Thus their 20% sprouting times were between 16 and 37 days from planting (with ‘Precocious’ and ‘Cheerfulness’ being the extremes); the 20% flowering times were within 70 and 94 days from planting (‘Tête-à-Tête’ and ‘Strong Gold’ being the earliest and ‘Precocious’ the latest) and flowering duration was between 16 and 38 days (‘Actaea’ and ‘Salome’). In addition, stem lengths varied between 19.6 cm (‘Tête-à-Tête’) and 48.5 cm (‘Golden Harvest’) and stem diameters were between 0.55 cm (‘Tête-à-Tête’) and 1.48 cm (‘Carlton’). The largest flower diameter occurred on ‘Sempre Avanti’ (12.1 cm) and the highest number of flowers per stem were found on ‘Tête-à-Tête’ and ‘Cheerfulness’. Therefore, this research showed that most cool climate narcissus cultivars can adapt successfully to Mediterranean ecological conditions suggesting that the cultivars used in landscape projects and the floriculture industries in Turkey could be extended. © 2019 International Society for Horticultural Science.

The Roses of Van and Rose Culture
(International Society for Horticultural Science, 2015) Alp, Ş.; Koyuncu, M.
According to some historians, the 18th century was the beginning of a change in the established culture of the Ottoman community due to the proliferation of European culture. During this period, great changes were observed in the types of plants used for decorating outdoor spaces, and in daily culture. For example, the rose, which was grown for many years in the palace gardens of Istanbul, lost its value after the importation of European roses, causing Ottoman roses to lose their traditional admiration. However, those old original Ottoman roses were preserved in some Anatolian cities and remained unaffected by the European conversion. One of these such regions is the Lake Van region in East Anatolia. Six different types of original roses were found in gardens and old graveyards in this region. Investigatons show that these roses have a great influence on Van's traditional handicrafts and cuisine. © International Society for Horticultural Science. All rights reserved.

Silent Guardians of Cemeteries in Turkey: Bulbous Plants
(International Society for Horticultural Science, 2013) Arslan, N.; Alp, Ş.; Koyuncu, M.
Cemeteries are unique and important places for many different societies. In Turkey, muslims bury their dead in cemeteries with specific methods of measurements, and they give a special importance to the cemeteries where their loved ones have been buried. It is their duty to keep those cemeteries clean, and to maintain the trees. It is also believed that plants worship God in their own way, which is why damaging grasses and trees in the cemeteries is considered inappropriate. Moreover, people usually decorate the cemeteries which hold the graves of their deceased relatives and they plant various plants on the top and in front of them. With today's urbanization there are increased regulations on the maintenance of graves. Thus, village cemeteries are a refuge for many native bulbous plants which are under threat of destruction. Planting in cemeteries eases their maintenance and they become beautiful places full of fragrant flowers and bulbous plants. In Turkey, the most common bulbous plants grown in cemeteries are: iris, tulip, daffodil, hyacinth and crown imperial. In this study, different flower bulbs that grow in different regions of Anatolia have been identified, and information is given on the bulbous plants grown in cemeteries in various parts of the country.
