WINTER ENTRY AND FROST TOLERANCE
- The majority of WOSR varieties are tolerant to low temperatures during winter. However, this tolerance is strongly correlated with the stage of development of the plant before winter.
- To obtain optimum frost tolerance, an oilseed rape plant needs to be well established, without stem elongation (an important criterion when choosing a variety).
- Plant check-up. Stronger plant establishment means higher tolerance. The goal is to obtain a biomass of 45 g/plant (>1.2 kg/m2 ), the main root with a length of 15 cm and a diameter of approximately 8 cm.
