For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe. [ 1 ] In this type of inflorescence , the peduncle is thick, long and fleshy, having small sessile unisexual flowers covered with one or more large green or colourful bracts (spathe).
A sterile spadix appendix protrudes from the mouth of the spathe tube. The appendix is covered by the leafy tip of the spathe, referred to as the spathe hood (or spathe lamina ). The lip along the mouth of the spathe tube, used as a landing platform for winged insects, is called the spathe flange .
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis and by the timing of its flowering (determinate and indeterminate). [2]
The inflorescence bears small flowers which are perfect, containing male and female structures. The flowers are contained in close together spirals on the spadix. The spadix is often elongated into a spike shape, but it can be globe-shaped or club-shaped. Beneath the spadix is the spathe, a type of bract. This is variable in shape, as well, but ...
The inflorescence's deep red color and texture contribute to the illusion that the spathe is a piece of meat. During bloom, the tip of the spadix is roughly human body temperature, which helps the perfume volatilize. The heated spadix creates a micro-convection in the cool ambient air, enhancing the transport of the scent.
For example, the ionic strength of the solution can have an effect on the activity coefficients of the analytes. [3] [4] The most common approach for accounting for matrix effects is to build a calibration curve using standard samples with known analyte concentration and which try to approximate the matrix of the sample as much as possible. [2]
The inflorescence is a spadix or spike surrounded by one or more bracts or spathes that become woody at maturity. The flowers are generally small and white, radially symmetric, and can be either uni- or bisexual. The sepals and petals usually number three each and may be distinct or joined at the base.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
