Les temp\u00e9ratures nocturnes tr\u00e8s froides du week-end, principalement dimanche matin, ont pu provoquer quelques d\u00e9g\u00e2ts de gel sur les jeunes semis. Le gel direct provoque un noircissement des cotyl\u00e9dons et un dess\u00e8chement de la plantule. Les jeunes germes peuvent prendre un aspect vitreux. Tant que le point v\u00e9g\u00e9tatif reste vivant, la plante peut survivre.<\/p>\n
