Crown gall causes stunting of growth. Both loss of yield and stunting of growth may occur when seedlings or young cuttings are infected in the early stages of plant growth. The lack of vigor, reduction in foliage, and water stress are associated with chronically diseased root systems.
1. In probability theory, a probability density function (pdf), or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value.
1 The area bounded by the curve of the density function and the x-axis is equal to 1, when computed over the domain of the variable. 2  The probability that a random variable assumes a value between a and b is equal to the area under the density function bounded by a and b.
