Effects of pretreatments on seed dormancy and germination in endemic Uludağ flax (Linum olympicum Boiss.) (Linaceae)

Generative production and evaluation of ornamental plant potential of an endemic flax species for ecological landscape applications

“…In our study cold-wet stratification with soaking in GA 3 solution, have a statistically positive effect on germination speed (T 50 ). In a similar study conducted by Kırmızı et al (2018) in L. olympicum seeds, GA 3 and cold stratification treatments shortened the average germination speed in L. olympicum seeds.…”

“…Temperature treatments were established in March 2020. According to the results of Kırmızı et al (2018), Kurt (2010), Meyer and Kitchen (1994), Milberg (1994), andPons (1991), 15 and 20 C were preferred as the germination medium temperature. Since successful results were obtained from the stratification applications in the previous studies, the seeds stored at 4 C for 3 months in the treatments combined with the stratification.…”

“…The seeds of native species are needed for seed renewal studies in gene banks, as well as for the restoration of natural habitats (Baskin & Baskin, 2020), for ex situ conservation studies of endemic species (Kırmızı et al, 2011; Yucel, 2022) and for germination (Baskin & Baskin, 2020; León‐Lobos et al, 2020). To carry out these conservation activities, it is necessary to determine the dormancy status of these endemic species, then to find out dormancy breaking treatments that end the dormancy of the seeds and to increase the seed germination rates (Kırmızı et al, 2019). It is not sustainable to collect seeds continuously from nature for these studies (Pérez‐Héctor & Chumana, 2020).…”

“…Today, there are various pressures on the biodiversity of ecosystems, which are constantly increasing in impact (Kırmızı et al, 2019; Pérez‐Héctor & Chumana, 2020). Human‐related factors, climate change, drought, and fires threaten ecosystems and endemic taxa.…”

Seed Germination Responses and Interspecific Variations to Different Incubation Temperatures in Eight Veronica Species Native to Korea

“…소독한 종자는 90×15mm petridish에 여과지 2매를 깔고 여과지가 마르지 않을 정도의 증류수를 주입한 후 치상하였다. Petridish 내 수분의 손실을 막기 위해 parafilm으로 밀봉한 뒤 aluminum foil을 두 겹 감싸 암처리 하였다(Kırmızı et al, 2018). 4°C의 항온 생장상(WIM-RL4, Daihan Scientific Co., Wonju, Korea)에서 각각 0(대조구), 3, 6주간 처리한 후 25°C의 항온 생장상에서 배양하며 발아율을 조 사하였다.…”
