Anatomical and morphological structure of the leaf of the genus Malus spp.

The article describes changes in the structure, leaves, (including mesophyll structure of midrib, distribution stomata, and number vascular bundles) Malus during growing season (from June to August) under influence prolonged drought. leaves anatomy morphology were investigated by methods light scanning electron microscopy. study was carried out on four representatives genus Malus: M. niedzwetzkyana Borkh., baccata ‘Pendula’, domestica ‘Eliza Rathke’, ‘Renet Simirenko’. drought size leaf plate stomata along stretch from August studied. cell circumference sclerenchyma ranged μm 27.33 (M. niedzwetzkyana) 81.92 (in ‘Elise Rathke’). varied 214.0 units Simirenko’) 304.0 ‘Pendula’), length 11.6 ‘Pendula’) 28.63 Rathke’), width 9.4 Rathke’) up 21.8 μm. trichomes 409.92 745.09 niedzwetzkyana). Also, anocytic stomatal type, number, different trichomes, presence wax cuticle, found druses calcium oxalate can be important for systematic phylogeny. Thanks these studies, it is possible suggest physiological adaptability apple trees drought, as well identify more resistant phenotypes breeding process develop cultivars.
