Morphological characteristics of the plant and reproductive capacity of yarrow (Achillea millefolium L.) seeds in dependence on pedo-ecological conditions

The paper analyzes the influence of soil type and its agrochemical characteristics on morphological productive parameters different yarrow (Achillea millefolium L.) populations. At 8 locations following fertility were analyzed: pH (H2 O), (KCl), CaCO3 (%), humus total N available P2 O5 K2 O (mg 100 g-1 soil). From parameters, measured: plant height, number leaves, diameter head, from fresh above-ground masses per plant, seeds yield hectare harvest index analyzed. Among quality seeds, germination energy, weight 1,000 examined. largest heads (13.6), a (1.9 cm) seed (386.0 kg ha-1) had population location Pančevo (Am1). In this variant, with highest energy (48.8%) (53.4%) obtained. in locality was second place (15,604.0 ha-1). hectare, obtained variant Am5 (location Starčevo "rit"). lowest values weakest found plants originating soils less natural located urban areas.
