Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces. [note 1]
They were used in different textbooks, e.g. Organogenesis of Flowers [7] by Rolf Sattler (1973), Botanische Bestimmungsübungen [8] by Stützel (2006) or Plant Systematics [9] by Simpson (2010). Floral Diagrams [ 1 ] (2010) by Ronse De Craene followed Eichler’s approach using the contemporary [ Note 1 ] APG II system .
Grisebach [5] (1854) used 4-integer series to represent the 4 whorls of floral parts in his textbook to describe characteristics of floral families, stating numbers of different organs separated by commas and highlighting fusion. Sachs [6] (1873) used them together with floral diagrams, he noted their advantage of being composed of "ordinary ...
In these mutants, such as APETALA2 in A. thaliana, carpels develop instead of sepals and stamen in place of petals. This means that, the verticils of the perianth are transformed into reproductive verticils. Mutations in type B genes – These mutations affect the corolla and the stamen, which are the intermediate verticils.
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
The two keel petals are fused at their bases [3] or stuck together [4] to form a boat-shaped structure that encloses the essential flower organs, [5] namely the androecium and gynoecium. Typically these flowers have a vexillary (i.e. descendingly imbricate or overlapping) aestivation .
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
