Application of Allium Hirtifolium for the Selection Process in Architecture and Environmental Sciences
(Association of Agricultural Technology in Southeast Asia, 2022) Alp, S.; Mohammadi Fallah, A.; Najafi, S.
Contrary to the popular belief, green space is not just a plant-covered, tabulated area. It is a symbol of a community's cultural and social thinking. So, its scope does not include just parks. Plants are the most important environmental variables in the landscape architecture and green space. Given the numerous problems in the field of green space, it seems necessary to provide methods for selecting plants with a systemic and holistic perspective. The genus Allium is one of the largest world florae. This study analyzed the karyotype and chromosome structure in five populations of Allium hirtifolium in different parts of Van, Turkey. Pre-treatment, fixation, hydrolysis and staining were done using root meristem; then microscopic samples were elucidated. The results showed that in all studied cells of each population, the basic chromosome number was 2n=2x=16 and all of them were diploid and X=8. Karyotype analysis of each population. It was also separately conducted and several indices including length of the long arm, length of the short arm, length of satellites, total length of the chromosome, arm ratio and centromere index. The length of chromosomes in all populations was estimated as 12.53 – 18.64 micrometers. Chromosomes 6 and 8 contained a secondary constriction and satellite. Karyotype formula for these populations was seven metacentric one submetacentric. © 2022 Association of Agricultural Technology in Southeast Asia. All rights reserved.
Basic Elements of the Traditional Garden Identity in the City of Van
(Academic Journals, 2010) Alp, S.; Ozturk, S.; Turkoglu, N.; Koyuncu, M.
Garden culture in the architectural patterns in and around the city of Van in the East Anatolian region of Turkey has been a tradition from the Urartian Iron Age Kingdom in Eastern Anatolia to the present. Until the end of the nineteenth century, the city of Van had an exclusive residential area where houses were surrounded by gardens. In this study, by exploring the texture of the old gardens in some current residential areas of the Van city center and its surroundings, we evaluated depending on the house-garden relationship, the street-house relationship, and size, garden elements, types of the plants. In this study the garden culture and understanding of the landscape will be brought from the time of the Urartians to our time and to the future. Further, an understanding of the traditional use of plant types in the city and their ornamental use will be recorded and perpetuated for regenerating into garden culture.
Botanical and Ecological Features of Rosa Laxa Retz Ssp Harputense T. Baytop (Kismiri Rose)
(int Soc Horticultural Science, 2010) Alp, S.; Koyuncu, M.
The tradition of gardening and growing ornamental plants goes back till Urartians, who lived 3000 years ago, in the Van region. Therefore, one often comes across different ornamental plants in old and traditional gardens in Van. Some of these are old garden roses, which have different origins and about which there is only little information. In this study, some information will be given about the botanical features and growing environment of the recently identified taxon, Rosa laxa Retz var. harputense T. Baytop. It grows in the gardens of the region but has not sufficiently been introduced to the scientific world. When it was first encountered in 1995, the identification key, concerning the identification of roses in P. H. Davis' "Flora of Turkey" (Volume IV, 1972), which is the primary source to identify the roses grown in Anatolia, was not adequate. This rose was both first identified in 1999 and published by T. Baytop in his book called "Old Ottoman Garden Roses (2001)". It has been understood, with the later studies, that this rose is a new variety that has not been identified so far. This kind of rose, known publicly as "kismiri rose," is one which has remontancy and pompon shaped, double flowers. Its flowers are fragrant, borne on stems in groups of 2-6 or singly, 2-2.5 cm in diameter, and petals that are white with lemon coloured bases. This rose, growing in the old gardens of Van and Elazig and in the monasteries in the region, is a variety of Rosa laxa Retz, which naturally grows in East Asia, North-west China and Siberia. Its origin is not exactly known or when and how this rose came to this region from such a long way.
Chemical Composition and Antioxidant Activity Ziziphora Clinopodioides Ecotypes From Turkey
(Ars Docendi, 2016) Alp, S.; Ercisli, S.; Dogan, H.; Temim, E.; Leto, A.; Zia-Ul-Haq, M.; Aladag, H.
The chemical composition of essential oil from eight ecotypes of Z. clinopodioides sampled from different points of Coruh valley located in Northeastern Turkey was determined and its total phenolic content and antioxidant activities were also evaluated. Seventeen components, representing 88.56-96.83% of the essential oil were identified by GC-MS. Differences between total phenolic content (varied between 43.41 and 55.71 mg GAE/100 g fresh weight base) and antioxidant activity (ranged from 3.60 to 4.20 mg/ml in DPPH assay) for the essential oil obtained from plant material harvest from different ecotypes were observed. The main components of all samples include (+)-pulegone, 1,8-cineole, limonene, menthol, beta-pinene, menthone, piperitenone and piperitone. Z. clinopodioides essential oil, total phenolic content and antioxidant activity affected by ecotype and environment conditions. The present study provides a theoretical basis for the potential application of essential oil from Z. clinopodioides to be used as a natural resource of antioxidant agents in food industry. The results also support the traditional use of Z. clinopodioides in Turkish folk medicine.
Determination of Possible Areas of Usage of Irises With Rhizome in Van and Its Environs in Plantation Works of Landscape Architecture
(int Soc Horticultural Science, 2011) Asur, F.; Alp, S.
This study was conducted to determine the phenological, morphological and ecological characteristics of 7 different species and subspecies of irises with rhizome in Van and its environs and define the possible areas of landscape architecture. The species were evaluated in terms of phenological characteristics such as the date of blooming, the duration of blooming and duration of maturation of their seeds. In addition, morphological characteristics, such as the plant length, the status of branching, flower characteristics and color were studied as well. Based on the ecological study of the species, some physical and chemical analyses were carried out using soil samples taken from 20 cm depth of the natural environment of the species. In addition, years of meteorological data related with their natural environment were examined. As a result of periodical studies, information was given regarding possible areas of usage of the species in landscape planning.
The Effect of Gibberellic Acid on Germination of Rosehip Seeds (Rosa Canina L.)
(int Soc Horticultural Science, 2010) Alp, S.; Ipek, A.; Arslan, N.
Rosa canina L. is one of the 25 Rosa species that grows naturally in Anatolia and spreads widely. The fruits of R. canina contain high levels of vitamin C. For this reason, the fruits of naturarally grown R. canina are picked and used to produce jam, marmelade, tea, and fruit juice. This plant is also used as a rootstock for ornamental roses and erosion prevention in the landscape. To meet the increasing demand, in Turkey R. canina and some other Rosa species are being put into production. In propagation using seed, dormancy constitutes a major problem. Several methods have been tried to eliminate this problem. In this study, the effect of GA(3) treatments on seed germination has been analysed. Seeds of a R. canina, genotype with small prickles were used. Treatment rates of control (non-soaked) 0 (distilled water), 250, 500, 1000 and 2000 ppm GA(3) were applied for 6 hours to the seeds. The seeds were germination in a cold greenhouse. During the first year, germination percentages ranged between 0.8 (control) - 5.3 (2000 ppm). Germination crates were kept another year and the germination rates in the second year ranged between 61.0 (250 ppm) - 76.5 (Control). It is useful to try, beside hormone practices, the other practices which will eliminate dormancy in order to increase the germination percentages in the first year. Being kept for two years afters its collection seeds of R. canina show a high level of germination without any additional process.
Essential Oil Content and Germination Behavior of Rosa Species Cultivated in the Lake Van Basin, Turkey
(int Soc Horticultural Science, 2015) Alp, S.; Aldemir, R.; Erdem, S. A.; Karagoz, S.
Roses are one of the most important flowers grown in Van lake basin. A lot of rose species and old roses were grown in the tradition of the Van garden and have been one of the indispensable elements in Van garden culture. Rosa x damascena Miller (Gul-i Muhammed) has also taken an important place in the traditional Van cuisine. Altogether 12 rose taxa that were identified in Anatolia are found in Van lake basin. Four of them are cultivated in the gardens of the region: Rosa dumalis Bechs, Rosa canina L., Rosa heckeliana Tratt. ssp. vanheurckiana (Crepin) O. Nilsson and Rosa pisiformis (Christ) D. Sosn. Bieb. The aim of this study is to evaluate and compare the contents of the essential oils obtained from the traded Isparta rose oil (Rosa x damascene var. trigintipetala) with the contents in Gul-i Muhammed rose oil (Rosa x damascena) using GC and GC/MS. Germination of this species' achenes grown in Van region is delayed due to a hard woody pericarp. Cellulose and lignin ratios of the species achenes were determined.
Extraction and Identification of Volatile Compounds in Rosa Laxa Retz Var Harputense T. Baytop "kişmiri Rose
(Centenary University, 2022) Alp, S.; Zarifikhosroshahi, M.; Yasa Ozturk, G.; Ercisli, S.
The gardening of ornamental plants comes back to ancient times (Urartians). Nowadays the gardening of ornamental plants is done worldwide as in the Van provinces of Türkiye. Old and traditional gardens can be seen in different regions of this province naturally. Among these plants, Rosa laxa Retzius var. harputense T. Baytop (Kişmiri rose), is an exotic plant coming from Central Asia. Kişmiri rose has semi-double and miniature flowers and blooms for about five months in the ecological conditions of Van. It has not only highly decorative but also has a light, pleasant, and enthusiastic fragrance. As far as we know there is no previously published on the volatile profile of Rosa laxa Retz var. harputense (Kişmiri rose). For this purpose, in this study, "Headspace Solid Phase Micro Extraction Gas Chromatography-Mass Spectrometry" (HS/SPME/GC/MS) was applied for the detection of volatile compounds of Kişmiri rose flowers. A total of 31 compounds of Kişmiri rose were identified and quantified using Gas Chromatography-Mass Spectrometry (GC/MS). Among these identified compounds, phenyl ethyl alcohol (26.59%), cis-3-hexenyl acetate (18.573%) was detected as the major ones. According to the obtained results, it is concluded that our species has also a Chinese origin. © 2022, Centenary University. All rights reserved.
Rose (Rosa Spp.) Genetic Resources of Lake Van Basin, Turkey: Endangered Antic Roses of Old Van Gardens
(Springer, 2010) Alp, S.; Koyuncu, M.
Anatolia has been an important gene center for the planting and improving of old garden roses until sixteenth century. The interest in old garden roses in Anatolia shifted to new modern roses raised in Europe after sixteenth century. Old garden roses have been able to survive in remote gardens of Anatolia such as Van gardens. In this study, the population status, flower characteristics and usage methods of old garden roses, which were planted in Van gardens and had a rich garden culture tradition since Urartu, have been investigated. As a result of this study which was carried out between 2004 and 2005, ten species, one being new, have been determined in gardens in and around Van. In terms of availability, four of these species were determined as being rare, four infrequent and two widespread in the area. The urban texture of Van has experienced a fast improvement in the last two decades as a result of modernism, and the old rose gardens, which were part of the local culture and genetic wealth, have been replaced by the big blocks of houses.
Roses and Their Varieties in the Ottoman Empire in the 19th Century
(int Soc Horticultural Science, 2015) Alp, S.; Karaca, Z.; Yaman, M. S.
In 1895, during the period of the Ottoman Empire, Agop Zakarian (a respected Agricultural Inspector) wrote a book called 'Rose and Its production' (Gul ve Mahsulati). The rose was described as a flower with a pleasant scent and prickles, belonging to the Verdiye family of trees or small bushes. He divided roses into ten different classes and described each class. In this manuscript, information about the classes mentioned in the book will be followed by information about rose production and the places where roses were raised.
