Munsell Plant Tissue Chart A botanist's colour guide, these 17 colour charts are used to determine and record the colour of plant tissues. This information is important to scientists working with growth rates, nutrient deficiencies, plant diseases, and other plant processes. In particular, it facilitates the diagnosis of adverse conditions responsible for the deteriation of plants and it serves as a stepping-stone to soil and plant tissue analyses. Why Use Plant Tissue Colour Charts? The colour plant tissues reflect the influence of light, critical temperatures, and the chemical composition of the soil, especially when the soil is deficient in certain major or minor nutrient elements. Sometimes the colour of plant tissue reveals the genetic origin of plants, effect of toxic substances, or the action of parasitic organisms. Charts provide scientists, students, and plant growers with information needed to respond to problems related to taxonomy, genetics, physiology, pathology, and plant nutrition.
