Mechanical rigidity and lignine content in different developmental phases of winter rape siliqua

V. Kratochvíl1
1 Oil-plant Breeding Institute, Opava

The lignine content and mechanical rigidity of siliquae ofBrassica napus L. ssp.oleifera f.biennis, cv. Třebíčská were studied. Experimental plants were harvested in five consecutive periods and developmental stages of siliquae were determined on the basis of the weight of 1000 seeds. During the development of siliquae a gradual accumulation of lignine takes place; the content reached its maximum in certain developmental phases and then decreased. The mechanical rigidity of siliquae had a similar tendency. There were statistically significant differences in both properties studied within individual developmental phases. A highly significant positive correlation was found between lignine content and mechanical consistency.
