Plant Passive Immunity: Micromorphological and Biochemical Features of the Maloideae (Rosaceae) External Tissues | Chapter 1 | Current Research Trends in Biological Science Vol. 1
The defeat of the fruits of fungal diseases is currently an important issue of plant science and is also of great economic importance. With the help of microscopic methods the leaves and fruits surface tissues of plants of four genera of the Maloideae subfamily were screened: Malus Mill., Pyrus L., Cydonia Mill., Mespilus L. and attempts were made to explain the dependence of mycosis damage on micro structural features. The species composition of fungi that cause damage to the Maloideae leaves and fruits in the Russia southern regions is analyzed. It is established that among pathogens with different types of parasitism there are common excitants, as well as highly specialized responses as on Mespilus germanica L. Higher resistance to the complex of fungal diseases, in comparison with apple and pear, was found in quince and medlar. This stability at the initial stage of the pathological process is associated with structural features such as micro morphology of the fruits and stomata ...
