La petite lentille d’eau (Lemna minor<\/em>)<\/strong> est une esp\u00e8ce de plante aquatique flottante<\/strong> de la famille des Arac\u00e9es<\/strong><\/mark>. Elle est c\u00e9l\u00e8bre pour \u00eatre l’un des v\u00e9g\u00e9taux \u00e0 fleurs les plus petits au monde, colonisant rapidement la surface des eaux douces et stagnantes.\u00a0<\/div>\n

      \n
    • La fronde :<\/strong> Ce que l’on prend pour une feuille est en r\u00e9alit\u00e9 une tige modifi\u00e9e appel\u00e9e \u00ab\u00a0fronde\u00a0\u00bb. Elle est de forme ovale \u00e0 arrondie, mesure entre 1,5 et 6 mm<\/strong> de diam\u00e8tre, et arbore une couleur vert clair. Elle contient des poches d’air lui permettant de flotter id\u00e9alement.<\/span>\u00a0<\/span><\/li>\n
    • Les racines :<\/strong> Sous chaque fronde pend une seule racine<\/strong> fine et blanch\u00e2tre, mesurant de 2 \u00e0 5 cm. Elle lui sert d’ancre stabilisatrice et de capteur de nutriments.<\/span>\u00a0<\/span><\/li>\n
    • Le regroupement :<\/strong> Bien qu’ind\u00e9pendantes, les frondes restent souvent soud\u00e9es par groupe de 2 \u00e0 4 individus apr\u00e8s s’\u00eatre divis\u00e9es.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

      \u00a0Mode de vie et reproduction<\/div>\n
      La petite lentille d’eau est une plante vivace<\/strong> extr\u00eamement vigoureuse. Sa particularit\u00e9 repose sur sa vitesse de prolif\u00e9ration :\u00a0<\/div>\n
        \n
      • \n
          \n
        • Multiplication asexu\u00e9e :<\/strong> Elle se reproduit principalement par division cellulaire (clonage). Dans des conditions optimales (lumi\u00e8re et eau riche en nutriments), sa population peut doubler en seulement 24 \u00e0 48 heures<\/strong>.<\/span>\u00a0<\/span><\/li>\n
        • Cycle hivernal :<\/strong> \u00c0 l’approche de l’hiver, elle produit des bourgeons denses ou des graines qui coulent au fond de l’eau. Au printemps, avec le r\u00e9chauffement de l’eau, ils remontent \u00e0 la surface pour recr\u00e9er des colonies.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

          \u00c9puration de l’eau :<\/strong> V\u00e9ritable filtre naturel, elle absorbe les nitrates et les phosphates en exc\u00e8s.<\/td>\nAsphyxie du milieu :<\/strong> En cas de prolif\u00e9ration excessive, elle forme un tapis opaque qui bloque la lumi\u00e8re et tue la flore immerg\u00e9e.<\/td>\n

          <\/tr>\n

          Super-aliment de demain :<\/strong> Sa mati\u00e8re s\u00e8che contient jusqu’\u00e0 45 % de prot\u00e9ines<\/strong>. Elle sert de nourriture pour les poissons, les canards et fait l’objet d’\u00e9tudes pour l’alimentation humaine.<\/td>\nBioconcentration :<\/strong> Elle absorbe tellement bien les \u00e9l\u00e9ments qu’elle accumule aussi les m\u00e9taux lourds et polluants, devenant alors toxique.<\/td>\n

          <\/tr>\n

          Anti-algues :<\/strong> En ombrageant le bassin, elle emp\u00eache les micro-algues de se d\u00e9velopper.<\/td>\nEsp\u00e8ce envahissante :<\/strong> Difficile \u00e0 \u00e9radiquer une fois install\u00e9e dans un petit plan d’eau ou un aquarium.<\/td>\n

          Utilisation en aquarium et bassin<\/div>\n
          En aquariophilie, Lemna minor<\/em><\/span> est appr\u00e9ci\u00e9e pour maintenir l’eau propre et offrir des zones d’ombre aux poissons timides. Cependant, sa croissance explosive exige un retrait manuel r\u00e9gulier<\/strong> (\u00e0 l’\u00e9puisette) pour \u00e9viter qu’elle n’envahisse toute la surface.<\/div>\n","protected":false},"excerpt":{"rendered":"
