title: Functional characterization of drought resistance in peach (Prunus petsica (L.) Batsch) cultivars damaged with Sharka disease
abstract: The article presents a comparative analysis of resistance to air and soil drought on the South oast of the Crimea in healthy Prunus persica (L.) Batsch plants and ones infected with Plum pox virus. The degree of damage to tree crowns varied from 10 % to 80 %. Structural differences in virus-free and infected plants were revealed: a decrease in leaf thickness and palisade index, the formation of large intercellular spaces in spongy tissue, necrotization in palisade chlorenchyma and a greater numb
