The morphological factors responsible for resistance are the thickness and the rigidity of the cellular wall, the distribution and the size of stomata, the rugosity of the leaf surface, the composition and amount of wax accumulated on the surface of the leaves, the leaf shape and, the most investigated, the central angle between the leaves, once, all these features make it difficult for pests and microorganisms to attack the plant.
