Abstract

The main goal of this study was to investigate the morphological development of the seedlings of Tilia spp. The experiments were carried out with seeds from three Tilia species. The seeds were harvested from trees in the region of Plovdiv on 30, 45, 60, 75 and 90 days after flowering. The seeds were sown in soil bed immediately after collecting. The sprouting percentage and percentage of developed and survived seedlings were recorded. In a 3-4 leaves development stage, the morphological characteristics of root, stem and leaves were determined. The seedlings have only developed from 90 days seeds. The differences between species were observed. The highest stem was measured in Tilia tomentosa Moench. The largest root system was developed in the seedlings of Tilia platyphyllos Scop. The seed propagation of linden is most effective by using 90 day old seeds.
