Aslay, Meral; Gökhan, Askan
Global biodiversity loss requires integrated ecological conservation and sustainable management approaches. Endemic taxa with restricted distributions and specialized ecological requirements are particularly vulnerable, necessitating both in situ and ex situ conservation strategies. This study presents the design of a native and endemic plant collection garden proposed for the Erzincan Horticultural Research Institute campus, developed through a conservation–propagation–exhibition integration model within a systematic spatial planning framework. The research followed a multi-stage methodology: (i) establishing a literature-based conceptual framework, (ii) conducting ecological analyses of climate, topography, and soil, (iii) applying multi-criteria species selection, and (iv) implementing computer-aided spatial design. Inventory results identified 48 plant taxa, including 19 endemic to Türkiye, with a dominance of geophytes, particularly species from the genus Fritillaria. The garden was structured through functional zoning, incorporating conservation, propagation, exhibition, education, and controlled sales units, aligned with ecological suitability and institutional sustainability. The findings indicate that such collection gardens serve not only as ex situ conservation sites but also as research infrastructures, genetic resource management platforms, and multifunctional landscapes that contribute to biodiversity conservation and regional development.

Aslay, Meral; Kalenderoğlu, Hakan; Gökhan, Askan
Bu çalışma, Türkiye'nin iklim değişikliğinin olumsuz etkilerinin giderek daha belirgin hissedildiği ve su stresi yaşayan ülkeler arasında bulunmasından dolayı, peyzaj planlamalarında kurakçıl peyzaj yaklaşımını ön plana çıkarmak amacıyla yürütülmüştür. Çalışmanın materyalini Erzincan Bahçe Kültürleri Araştırma Enstitüsüne ait süs bitkileri koleksiyon bahçesindeki türler ile Erzincan kent merkezi ve 8 farklı ilçesinde bulunan bazı doğal bitkilerden oluşan Ağlayan gelin (Fritillaria imperialis), Allı Gelin (Hesperis isatidea), Çöven (Gypsophila sp.) Osman çiçeği (Vinca soneri), Yayla süseni (İris spuria ssp. Musulmanica), Püsküllübaş (Muscari tenuiflorum), Keşişbaşı (Muscari azureum), Yaban lalesi (Tulipa julia), Sümbül (Hyacinthus orientalis), Çiriş (Eremurus spectabilis), Mürver otu (Sambucus ebulus L), Camışkıran (Sicilia siberica subsp. armena), Boyacı sumağı (Cotinus coggyria) peyzaj değeri olan doğal türler oluşturmaktadır. Çalışma doğal bitki türlerinin kentsel planlamaya dahil edilmesinin sağlayacağı mali avantajların belirlenmesi, varsa eksikliklerin giderilmesine yönelik öneriler sunulması, iklim dostu tasarımlarım artırılması, bitkilerin günümüz iklim şartlarına uyum sağlanabilmesi ve bu alanda çalışan peyzaj mimarları, kentin karar vericileri, şehir plancıları ve araştırmacılar için bir referans teşkil etmesi amaçlanmaktadır. Erzincan Binali Yıldırım Üniversitesi Yalnızbağ Yerleşkesinde oluşturulan ‘Kurakçıl Mini Botanik Bahçesinde’ kültüre alınan 13 farklı türün tamamına yakınının gerek peyzaj özellikleri gerekse iklim değişikliği sürecinde peyzaj tasarımının ana öğesi haline getirebilecek türler olduğu tespit edilmiştir. Kentin karar vericileriyle yapılacak görüşmelerle, bu türlerin gelecekteki peyzaj planlamalarında kullanılması teşvik edilecektir. Böylece, iklim dostu peyzaj planlamaları için kaynak değeri oluşturulacaktır.

Yildiz, Faruk; Aslay, Meral; Kaya, Ozkan
Fritillaria spp., comprising perennial bulbous plants of significant medicinal and ornamental value, face high endangerment in their natural habitats. Despite their importance, the reproductive characteristics and adaptive evolution mechanisms of these species remain incompletely understood. This study focused on the pollination strategies and reproductive biology of Fritillaria imperialis L. The research was conducted at the Erzincan Horticultural Research Institute in Türkiye. Our investigation categorized the flowering process of F. imperialis into nine distinct phases. Through comprehensive assessments of the pollen/ovule ratio, self-incompatibility index (SII), and ex situ pollination experiments, we observed high levels of self-incompatibility and allogamy in F. imperialis. Our findings revealed that pollination of F. imperialis primarily relied on pollen vectors, with Apis mellifera and Bombus terrestris identified as the most effective pollinators. Furthermore, average seed set rate, seed production, and seed viability were quantified at 80.5%, 228 seeds, and 86.3%, respectively. The average numbers of pollen viability and pollen grains were measured at 93% and 702,000, respectively. This comprehensive analysis of the reproductive biology of F. imperialis provides crucial insights for the conservation and genetic management of this highly valuable species. The findings contribute to a deeper understanding of the reproductive strategies employed by Fritillaria spp., which may inform future conservation efforts and breeding programs for these endangered plants.

Aslay, Meral; Yıldız, Faruk; Kaya, Ozkan; Bita-Nicolae, Claudia
Fritillaria is highly endangered in their natural habitats, and these species are perennial bulbous plants with an important medicinal and ornamental value whose reproductive strategies and adaptive evolution mechanisms are still not fully clear. Therefore, the reproductive strategies of endemic species, like Fritillaria michailovskyi Fomin are important to detect the community structure and the diversity patterns of ornamental plants. The current paper on the reproductive strategy of F. michailovskyi, a rare endemic species, was carried out at the Erzincan Horticultural Research Institute, Turkey. Our results indicate that the flowering stages of F. michailovskyi may be divided into eight phases. According to pollination experiments and the pollen/ovule ratio, and the self-incompatibility index (SII) in an ex-situ population, F. michailovskyi indicated high levels of xenogamy and self-incompatibility. It was determined that the pollination of F. michailovskyi mostly depended on pollen vectors, and the effective pollinators of F. michailovskyi were Apis mellifera and Bombus terrestris. In addition, average seed number, seed germination, and average seed viability were found as 144, 46%, and 67%, respectively. The stigma receptivity, pollen grains, and pollen viability were detected as 83%, 252,000, and 95%, respectively. Our study is the first report providing a detailed explanation of the reproductive strategy of this rare endemic species, which could aid in the genetic evolution and conservation of this valuable taxa.

Yıldız, Faruk; Aslay, Meral; Kandemir, Ali; Kaya, Ozkan
Fritillaria aurea, unlike other Fritillaria species, is a narrowly endemic species. It has a brown checkered speckled color on each tepal and also has regular yellow intense colors on the tepals. Its large bell-shaped appearance when the flower is open is one of its most striking ornamental features. However, F. aurea plant numbers are limited in their natural habitats, and their numbers are decreasing day by day; they are even confronted with the risk of extinction owing to the damage resulting from human activities. This detailed investigation of reproductive biology plays a vital role in determining the evolutionary success and survival of F. aurea, largely in determining the effectiveness of their reproductive performance. Our results indicate that the species exhibits a very low partial dichogamy and herkogamy structure, as well as self-incompatible pollination. The flowering period ranges from March to April. Average seed viability, average seed number, and seed germination were determined as 71%, 255, and 45%, respectively. The pollen viability, pollen grains, and stigma receptivity were found as 96%, 392.000, and 85%, respectively. The pollen/ovule ratio (P/O) and self-incompatibility index (SII) in the spontaneous cross-pollination were detected as 1537 and 0, respectively. Flowers of F. aurea were visited by several insect species, mostly honeybees (Apis mellifera); Bombus sp. and Vespa sp. also played a minor role in pollination. To sum up, these results not only lay a solid foundation for further reproductive biology investigations to more broadly reveal the mechanisms of F. aurea endangerment in the future but also provide a reliable theoretical basis for hybridization breeding of parents.
