INTRODUCTION OF ENDEMIC Allium tuncelianum KOLLMAN FROM HOT AND TEMPERATE CLIMATE TO SEMI-ARID CLIMATIC CONDITIONS

Abstract

Allium tuncelianum (Tunceli garlic) is a single cloved important threatened endemic geophyte of high commercial importance that grows scattered on hot temperate mountains under oak trees in the eastern Turkish province of Tunceli. Tunceli garlic is used diversely in salads, foods and in pharmaceutical industry. They also offer a rich choice for their use in rock gardens and landscaping. There is need to develop appropriate agronomic practices for its propagation outside its habitat. In line with this objective, the study optimized planting time (1 st September, 15 th September and 1 st October) of A. tuncelianum on mild alkaline soils under semi-arid climatic conditions of Diyarbakir, Turkey. The results of the study showed positive gain in morphological characteristics such that bulb diameter of the plants changed between 3.43 to 4.60 cm, bulb circumference ranged 14.4 to 16.1 cm and bulb weight had a range of 35.9 and 46.3 g. These results underscore positive effects of early and mid September plantings of Tunceli garlic outside its habitat under semi-arid conditions for economic production with early harvest.

Agronomic responses of four garlic genotypes in two different locations

“…It is well known that some genotypes prefer a specific environment or are widely adapted to several environments (Thanh et al, 2016;Begna, 2020;Belay et al, 2020;Sultan & Raina, 2020;Casals et al, 2023). Nevertheless, it is also known that some garlic varieties have phenotypic plasticity in response to different environments (Volk & Stern, 2009;Kizil & Khawar, 2017;Sánchez-Virosta et al, 2021). Some studies have revealed that different agronomic responses exist in garlic varieties under various environmental factors e.g., photoperiod and temperature (Atif et al, 2019;Mathew et al, 2011), water stress (Sánchez-Virosta & Sánchez-Gómez, 2019), different fertilizer levels (Shree et al, 2014), climatic changes (Tchórzewska et al, 2017;Mahmudah et al, 2021), and planting time (Alsup-Egbers et al, 2020).…”

In vitro Gynogenic Plant Production in Allium tuncelianum (Kollman) Özhatay, Matthew & Şiraneci

“…A. tuncelianum is considered as a vulnerable threatened plant species (Etoh and Simon 2002;Ipek et al 2008;Kizil et al 2012). This species is suitable for cultivation under eld conditions by planting bulbs gathered from nature (Kizil and Khawar 2017). However, there is no record of any breeding program aiming to develop new varieties of this species with desired agronomical traits.…”
