A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it is easier to determine whether the spore print is pure white or, rather, very slightly pigmented.
Black point (blackpoint, kernel smudge or just smudge [1]) is often considered a fungal disease that affects wheat, barley and rye.It is thought to be caused by various species of Alternaria, Fusarium, and Helminthosporium, and possibly other fungal genera. [2]
After initial infection, the entire kernel is converted into a sorus consisting of a dark brown to black mass of teliospores covered by a modified periderm, which is thin and papery. The sorus is light to dark brown and is called a bunt ball. The bunt balls resemble wheat kernels but tend to be more spherical.
Categorization of racial groups by reference to skin color is common in classical antiquity. [7] For example, it is found in e.g. Physiognomica, a Greek treatise dated to c. 300 BC. The transmission of the "color terminology" for race from antiquity to early anthropology in 17th century Europe took place via rabbinical literature.
Karnal bunt (also known as partial bunt) is a fungal disease of wheat, durum wheat, and triticale.The smut fungus Tilletia indica, a basidiomycete, invades the kernels and obtains nutrients from the endosperm, leaving behind waste products with a disagreeable odor that makes bunted kernels too unpalatable for use in flour or pasta.
“Toasted skin syndrome is the non-medical term for a skin condition that is caused by chronic exposure to low levels of heat or specific types of radiation," explains Dr. Rachel Nazarian, ...
Wheat is the primary host, and barberry is the alternate host. [citation needed] The rust is sometimes termed "red rust" or "red dust" [3] [16] owing to the spores on the leaf surfaces that range from orange to dark-red in color. Later, the spores change and become dark in color, which gives rise to another common name, "black rust". [17] [2]
Skin colors according to von Luschan's chromatic scale. Von Luschan's chromatic scale (VLS) is a method of classifying skin color. It is also called the von Luschan scale or von Luschan's scale. It is named after its inventor, Felix von Luschan. The equipment consisted of 36 opaque glass tiles which were compared to the subject's skin, ideally ...
