Selection of European larch for seed productivity

Abstract

The values characterizing size and quality parameters of raw materials of European larch forest seed and sowing properties of seeds. It is noted that in the procurement of European larch cones should be taken into account that in the same tree may be cones like last year and the current one. Seeds from last year’s cones do not germinate, so they can not collect. The main feature of the cones of this year from last year is a shade of color scales. Last yea r’s cones are tarnished brown color, and the current – light brown. Furthermore, in the last year cone scales usually bent more than the cone of the year. There exist forms of European larch cones with sprouted shoots, but significant differences between them and conventional forms of cones are not revealed. Scientific interest for further research are cones with late ripening. Studies have shown that the seeds of which have a higher germination, they are significantly wider than usual, but the seeds germinate later by an average of 5 days. When conducting selection of European larch seed production need to select trees with large cones. Lined reliably, that the longer the cones, the more seeds contained therein, the greater the number of falls during the drying cone and the greater the weight of 1,000 seeds.
