Studies on snow-harm in rape varieties

[摘要] Reduced sugar, dry mattar and carbon dioxide assimilation in leaf were larger in B. napus than in B. campestris, but under snow condition these subustances were found to be consumed especially by respiration in B. napus plants. It may be ascribable to the fact that the rape varieties of B. campestris have stronger snow resistivity than those of B. mapus.
