Il y a beaucoup d\u2019eau dans les sodas (Coca, Pepsi, autres). Une graine arros\u00e9e avec du soda pourrait peut-\u00eatre commencer \u00e0 germer&#8230; Mais elle risque de ne pas aller tr\u00e8s loin\u00a0! D\u2019abord, le Coca est tr\u00e8s acide. Cette acidit\u00e9 peut perturber le fonctionnement de la graine et surtout ab\u00eemer les jeunes racines. Mais le principal probl\u00e8me vient de la grande quantit\u00e9 de sucre contenu dans les sodas. Dans le sol, ce sucre peut favoriser le d\u00e9veloppement de micro-organismes, rendre le milieu collant. Le sucre va aussi g\u00eaner les mouvements de l\u2019eau dans le sol et emp\u00eacher son entr\u00e9e dans la graine. Or, pour germer, celle-ci doit absorber beaucoup d\u2019eau avant m\u00eame que la jeune racine ne s\u2019allonge. Donc, m\u00eame si le Coca contient de l\u2019eau, ce n\u2019est vraiment pas la meilleure boisson pour une plante. Pour faire pousser une graine, rien ne vaut un verre d\u2019eau, sans sucre et sans bulles.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"Une graine a besoin d&rsquo;eau pour germer.
