Spadix (botany) Typically, the stigmas are no longer receptive when pollen is released which prevents self-fertilization. We also have Compound Spadix Inflorescence in which the axis is branched. Usually whole Inflorescence is covered by a stiff boat shaped path for example- Coconut. Spadix (botany) In botany, a spadix ( ; plural spadices , ) is a type of spike inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known "Anthurium"
Spin coating to 80 revolutions per second for 30 to 60 seconds. Spin coating Spin coating is a procedure used to deposit uniform thin films to flat substrates. Usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. The substrate is then rotated at high speed in order to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. Rotation is continued while the fluid spins off the edges of the substrate, until the
