   Strain
   In plants a group of individuals of a common origin, usually a more narrowly defined group than a cultivar. For pathogens, the descendants of a single isolation in pure culture; an isolate. Also a group of similar isolates; a race. In plant viruses: a group of virus isolates having most of their antigens in common.

7. 
   Strain
   Relative deformation of a material, for example, repair tissue. Motion at the fracture site in itself is not the important feature, but the resulting relative deformation, which is called strain (dL/L), of the healing tissues. As strain is a ratio (displacement of fragments divided by width of fracture gap), very high levels of strain may be presen...

8. 
   Strain
   Change per unit length in a linear dimension of a part or specimen, usually expressed in % Strain, as used with most mechanical tests, is based on original length of the specimen. True or natural strain is based on instantaneous length, and is equal to: ln X l lo , where l is instantaneous length and lo is original length of the specimen. Shear strain is the change in angle between two lines originally at right angles.

   Strain
   When a structure or component is subjected to stress individual fibres or elements in the material either lengthen or shorten. Strain is a measure of how much these elements extend or contract, and is defined as the change in length divided by the original length of the element. Strains can be defined at a point if the strained element is considere...

    strain
    Strain is present in a molecular entity or transition structure if the energy is enhanced because of unfavourable bond lengths, bond angles, or dihedral angles ('torsional strain') relative to a standard. It is quantitatively defined as the standard enthalpy of a structure relative to a strainless structure (real or hypothetical) made up from the same atoms with the same types of bonding. (The enthalpy of formation of cyclopropane is 53.6 kJ mol^-1, whereas the...
