|Description:||The article considers information about phytocoenotic role and popularity of linden stands on the territory of the Republic of Belarus. There have in vestigated progeny of small-leafed linden and large-leaved linden by means of unit sample analysis in correspondence with existing standards. There has been determined viability, mass of 1,000 pieces of seeds, laboratory germina tion. It has been deter-mined that viability of small-leafed linden and large-leaved linden seeds being analyzed is quite high comprising 70–74%. The highest viability (74%) is specific for large-leaved linden earthed during 6 months since spring till autumn. Mass of 1,000 pieces of seeds comprised from 31.8 till 142.5 g. The results of linden seeds by various methods have b een shown. Along with tr aditional ways of preseed treatment (seed-soaking treatment, seed-soaking treatment in potassium permanganate) there have been tested more complex methods of preseed treatment by means of affecting them by positive and negative temperatures as well as by variable temperature modes. Determining laboratory germination, there have been noticed separate seedlings when small-leafed linden seeds being earthed for 2 months at +18°C, then for 2 months at 0°C, then again for 2 months at +18°C in tight dishware. There have been investigated the effect of depth of seed placement on their germinability. The highest germinability (23.0%) is specific for seeds placed 3.5–4.0 cm in depth.|
