Summary

Description	Français : Des deux noix, la noix d’Amérique (Juglans nigra), à gauche, a la coquille la plus dure. De plus, ses parois internes sont elles aussi très dures, ce qui rend l’extraction de l’amande comestible très malaisée, par comparaison à la noix commune (Juglans regia), à droite, dont les parois internes sont fines et facilement détachables, tandis que la coque externe se sépare assez aisément en deux.

JPEG file comment	Comparaison des coquilles de deux noix : une noix d’Amérique (Juglans nigra) et une noix commune (Juglans regia). La noix d’Amérique est beaucoup plus dure et ses parois internes sont très dures elles aussi, ce qui rend l’extraction de l’amande beaucoup plus malaisée. La noix commune a des parois internes fines et relativement faciles à détacher. La coque extérieure est moins dure.
