In this study, the usability of super absorbent polymers (SAP) and its effects on water consumption, irrigation and labor costs and plant growth in ornamental plant cultivation were investigated by using Euonymus japonicus 'Aureomarginatus,' peat, river sand, and Wesoorb branded SAP. For a period of 152 days, the growth of the control groups without SAP and experimental groups with SAP was monitored, and the obtained results were compared. It was determined that SAP balanced the moisture of the medium with a controlled release and decreased the water stress in the plant and differentiated the root structure. The use of SAP in Euonymus japonicus 'Aureomarginatus' cultivation reduced water use by 45% on average and labor costs by 48% on average. It was observed that SAP can be used in ornamental plant cultivation and will decrease production costs.
This study focused on seed propagation and ex situ conservation of the endemic species Centaurea hermannii F. Hermann. Plant properties such as vegetation cycle, adaptation to the cultivation environment, morphological characteristics of the plants and seeds, and esthetic properties as an ornamental variety were investigated. The percentage of viability of the seeds, as well as the effects of different seed germination methods when applied to the germination speed, were also explored. C. hermannii specimens planted in soil adapted quickly under field conditions and flowered over a period of two months, with a bright-orange color and glossy blossoms. In addition, the plants displayed all the type-specific botanical and esthetic properties, as well as provided value as an ornamental plant. An ex situ conservation area was created with the plants collected. To determine the best germination conditions for C. hermannii seeds, various methods were explored. Among these, a combination of 200 ppm of GA3 treatment during a three-month storage period at 4 °C, followed by cold-wet stratification at 4 °C for three months, produced the best results in terms of mean percentage germination (70.5 %) and mean germination speed (3 days).
Çalışmada risk altındaki kültür mirası kapsamında ahşap yığma camiler değerlendirilmiştir. Ahşap mimarlık mirası olarak ahşap yığma camiler, tarihi, özgün mekânsal kurgusu, ahşap malzeme kullanımı ve yapı teknolojisi ile birlikte önemli yapısal kültür birikimini barındırmaktadır. Karadeniz Bölgesi'ndeki ahşap yığma camilerin işlevi ile ilişkili olarak; mevcut durum tespiti, mekânsal özelliklerin analizi, yapısal durum ve fiziki koşullara dayanımı konularında birçok araştırma bulunmaktadır. Türkiye'de Karadeniz Bölgesi'nde yoğunlaşan ahşap yığma camiler için doğa kaynaklı risklerin tespiti de koruma açısından öncelikli konulardan biridir. Türkiye için yapılı fiziksel çevre üzerinde oluşturduğu etki ve can kayıpları açısından deprem tehlikesi ilk sıradadır. Depremle birlikte sel ve yangın gibi tehlikeler de önemli risk oluşturmaktadır. Son yıllarda küresel iklim değişikliği ile birlikte yağış rejimindeki değişim, ani yağışlara ve buna bağlı su baskınlarına neden olmaktadır. Çalışmada Karadeniz Bölgesi kapsamında farklı illerden 168 ahşap yığma cami literatürden elde edilen verilere bağlı olarak incelenmiştir. Değerlendirmede doğa kaynaklı tehlikeler ve caminin kullanım süreciyle bağlantılı olarak yapıya müdahaleler dikkate alınmıştır. Camilerin yapım yılı, konumu, kullanım durumu ve özgün yapıya müdahaleler, il ölçeğinde gruplandırılarak, tehdidi altında oldukları tehlikeler kapsamında riskleri tartışılmıştır. Araştırma sonuçları, ahşap yığma camileri koruma kapsamında doğa kaynaklı risklerle birlikte kullanım kaynaklı risklerin de tespit edilmesinin önemli olduğunu göstermektedir. Ahşap yığma camiler büyük ölçüde meskûn alan dışında ve mezarlık alanındadır. Önemli sayıda cami nehir yakınında konumludur. Ahşap yığma camilerin birçoğunda muhdes ek ve yapısal müdahale bulunmaktadır. Ahşap mimarlık mirasının önemli bir bileşeni olan ahşap yığma camilere yönelik riskler bütüncül olarak ele alınmalıdır.
T HIS study was carried out in two regions: Küçükdeliller village in Osmangazi district in Bursa province (altitude: 1100 m) and Yalova (altitude: 5 m). In the study, an incubation room (with an average of 20.33°C and 88.2% relative humidity) belonging to Yalova Atatürk Horticultural Central Research Institute and a warehouse with uncontrolled conditions were used. In this study, it was aimed to reproduce Fritillaria imperialis L. by different methods in different regions outside its natural distribution area and to monitor the development course of bulb groups under export size (10/12, 12/14, and 14/16 cm) in these locations. The best result in the reproduction of Fritillaria imperialis L. was obtained from the practice of incubating, cross-cutting application in the Küçükdeliller ecology, and the chipping application after the incubation process in the same ecology. Although there were losses in the number of bulb planted in both regions in the bulb groups under export size, increases in weight and circumference of the bulbs have been found over the years, especially in Küçükdeliller ecology. As a result of the research, it was determined that the ecology of Küçükdeliller is significantly better than the ecology of Yalova regarding the growth of bulb under export size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
