Cette diversit\u00e9 nous a conduit \u00e0 mettre en place des recherches comparatives visant \u00e0 la description de son cycle reproducteur. L&rsquo;un des enjeux de ces recherches concerne le r\u00e9chauffement du climat et son impact \u00e9conomique pour les r\u00e9gions de production datti\u00e8re. Il s&rsquo;agit aussi de savoir si le palmier dattier pourrait \u00eatre un indicateur fiable de ces m\u00eames changements. <\/strong><\/span><\/span><\/span><\/div>\n<div style=\"text-align: justify;\">\u00a0<\/div>\n<div style=\"text-align: justify;\">\n<div style=\"text-align: justify;\">\n<div style=\"text-align: justify;\"><a title=\"\" href=\"http:\/\/www.listephoenix.com\/?attachment_id=4928\" target=\"\" rel=\"attachment wp-att-4928\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4928 alignnone\" title=\"\" src=\"http:\/\/www.listephoenix.com\/wp-content\/uploads\/2013\/01\/Peru-carte-climatique.gif\" alt=\"Peru carte climatique\" width=\"575\" height=\"470\" \/><\/a><\/div>\n<div>\u00a0<\/div>\n<div><span style=\"font-size: 12px;\"><span style=\"font-family: tahoma,geneva,sans-serif;\"><span style=\"color: #008000;\"><strong>Pr\u00e9paration du suivi ph\u00e9nologique du dattier sur la c\u00f4te Pacifique des Am\u00e9riques. <\/strong><\/span><\/span><\/span><span style=\"font-size: 12px;\"><span style=\"font-family: tahoma,geneva,sans-serif;\">La C\u00f4te Pacifique du continent am\u00e9ricain offre la possibilit\u00e9 d&rsquo;effectuer un suivi ph\u00e9nologique continu sur une tr\u00e8s grande \u00e9tendue latitudinale, depuis le nord de la Californie jusqu&rsquo;au Chili central. Des contacts ont \u00e9t\u00e9 pris avec plusieurs chercheurs des Universit\u00e9s de Guayaquil, Lima et Santiago, pour mettre en place un suivi sur la portion Equateur-P\u00e9rou-Chili. Ce suivi partira d&rsquo;Esmeraldas dans le nord de l&rsquo;Equateur jusqu&rsquo;\u00e0 La Serena pr\u00e8s de Santiago. Les individus \u00e0 suivre sont en cours de rep\u00e9rage. De v\u00e9ritables palmeraies existent dans certaines localit\u00e9s du P\u00e9rou et du Chili. Dans d&rsquo;autres secteurs, il faut chercher les rares exemplaires plant\u00e9s pour l&rsquo;ornement ou utiliser les ressources de stations de recherches qui en poss\u00e8dent \u00e0 titre exp\u00e9rimental.
