Abstract
The aim of the studies was to evaluate the influence
of sowing rate, foliar fertilization (Basfoliar fertilizer 6-12-6)
and chemical composition on the mechanical properties of narrow-
leaved lupine seeds of cultivars Bojar and Regent. Single
seeds were burdened in the direction perpendicular to the parting
plane of cotyledons with constant speed 10 mm∙min-1. The crop
year and cultivar have significantly differentiated the value of all
the analyzed strength parameters of narrow-leaved lupine seeds.
The seeds of cultivar Bojar had significantly higher values of all
the strength parameters. The designated strength parameters of
lupine seeds were negatively correlated with ash content, fiber
and protein except for the destructive force. They were also
positively correlated with the fat content.
