Abstract
In Plantago major L. an enormous genetic variability is present for a large number of plant traits (Van Dijk and Van Delden, 1981; Kuiper, 1982, 1983; Kuiper and Smid, 1985). Differences in relative growth rates (RGR) for shoot and roots were observed among inbred lines of P. major. Inbred lines also differed largely in the rate of growth responses, when plants were transferred from a nutrient-rich growth solution (100%) to a 50 times diluted nutrient solution (2%) and vice versa. Quick growth responses in plants of an inbred line belonging to subspecies pleiosperma (Pilger) transferred from a 100% to a 2% solution (100–2% plants) were accompanied by a rapid decrease in shoot to root ratio (S/R). The rapidity of the responses in P. major ssp pleiosperma and preliminary determinations of the contents of several ions raised the question about the decisive role of the availability of minerals in growth regulation.
