Sowing / sprouting. The duration of this phase varies in yellow lupin, on the average, from 10 to 16 days (Наймарк, 1976). Such variation depends on the level of daily average temperatures in soil, presence of moisture, and depth of sowed of seeds. Differences between varieties have had no effect on the duration of this phase under identical conditions of cultivation. In this phase, the growing point is on stages I-II of organogenesis.
