Abstract

Plant height is strongly influenced by seeding density, in Pamela variety and Exotic and PR46W14 hybrids it increases from 50 g.s./m² to 150 g.s./m², then fades and tends to decrease. The average number of branches varies from 12.6 at PR46W14 hybrid to 28.87 at Extend hybrid at the density of 50 g.s./m². Increasing the seeding density and implicitly the plant density over 100 g.s./m² reduces the number of main branches per plant. It should be noted that higher densities of seeding stimulates the formation of main branches per plant. Number of main branches per plant varies between 3.23 in PR46W14 hybrid at a density of 50 g.s./m² to 5.57 in Exotic hybrid at a density of 100 g.s./m². Number of secondary branches per plant has maximum values at 50 g.s./m² in Extend hybrid. Average number of capsules per plant has values between 140.87 in PR46W14 hybrid and 415.17 in Extend hybrid.
