Evaluation of Seedling Development and Physical Characteristics, Viability and Germination of Seeds in Some Lamiaceae Taxa

Abstract

The Flora of Türkiye is very rich in the members of the Lamiaceae family. This study, it was aimed to investigate some physical characteristics, viability, germination performance of their seeds, and initial seedling development of 16 taxa belonging to the Lamiaceae family collected from the natural area. According to the results, the highest and lowest viability value was recorded in S. aethiopis (82.86%) and in S.yosgadensis (10.71%), respectively. The root length values of the taxa changed between 25.57mm (T.sipyleus)-66.82mm (S.aethiopis) at the end of the 21st day. The shoot lengths of the seedlings were determined to vary between 3.12mm (T.sipyleus)-22.41 mm (P.armeniaca). The seed width and length values of taxa varied between 0.911-2.788mm and 0.999-5.055mm, respectively. Values varying between 0.432-0.865 were calculated according to the geometric properties determined by proportioning the width and length dimensions of the seeds. The obtained results will be useful for studies on the cultivation of these taxa.

Seed germination ability and biochemical features of two Teucrium taxa (germander) of Lamiaceae

“…Leaf widths of seedlings belonging to T. chamaedrys were measured in the samples from both natural and trial area as 1.02 to 1.04 cm., and leaf lengths were 1.59 to 1.71 cm, respectively (Table 3). In a study by Şenkal and Uskutoğlu (2022), the data obtained because of the germination trials of the seeds collected from nature in Yozgat, Türkiye had a similar result with the current study. In T. polium, the leaf width was measured as 0.36 to 0.41 and the length as 1.08 to 1.22.…”
