Influence of maturation regulators on mechanical properties of stems in rapeseed
The aim of the research was to determine the influence of Caramba matuation regulator (applied in vaious doses both in the autumn and spring) on mechanical properties of stems in rapeseed. During examination process, biometrical features of plants such as height, thickness of root collar, thickness of stem at base and at height of 30 cm were determined. The maximum force necessary to break the stem at those points was also determined along with the coefficient of stems rigidity at the root collar and at the height of 30 cm. Three plants of winter rapeseed varieties (Lisek, Kaszub, Californium) were examined throughout the study.The research was conducted over a period of 3.years and its results allow us to evaluate the effect of the Caramba maturation regulator on those features of stems which determine their strength parameters. This will allow growers to choose optimum dose and period of applying the regulator as well as to determine its effect on lodging and freezing of plants in the winter.
