schijnvrucht Explanation: 'anthocarp' schijnt toch synoniem te zijn met 'schijnvrucht' glossary of seed and fruit morphological terms: anthocarp = anthocarpous fruit = accessory fruit = pseudocarp = false fruit: a pericardium with attached floral parts that have ondergone a marked development during post-fertilisation to aid in the dissemination of the seed. The accessory structures to the pericarpia usually enlarge or become fleshy after fertilisation (e.g. the hypanthium of an apple), or disarticulate as in grass fruits (Spjut 1994) pericarpium: a ripened ovary (including the seed(s)) without any attached parts; its wall referred to as pericarp (Spjut 1994) pericarp: the wall of the ovary at the fruiting stage, consisting of epicarp, mesocarp and endocarp (these three layers are typically differentiated in drupes, but not in fleshy or dry fruits where the pericarp is more or less homogenous http://www.kew.org/ucm/groups/public/documents/document/kppc... http://en.wikipedia.org/wiki/Accessory_fruit http://nl.wikipedia.org/wiki/Schijnvrucht floral parts: http://en.wikipedia.org/wiki/File:Pome_apples_text.jpg Een vrucht is het volledig ontwikkeld en gerijpt vruchtbeginsel. Zijn er nog andere delen van de bloem betrokken, dan is het een schijnvrucht. Schijnvrucht 1: Vrucht in/op gezwollen bloembodem, uit bloemen met vele niet vergroeide vruchtbladen ontstaan (Pome) Pitvrucht (klokhuis is binnenste deel van vrucht, bloemboden vlezig) Appel http://istang.home.xs4all.nl/martina/pdf/Vruchten-en-Zaden.p...

Reference: anthocarp Reference information: ... de vrucht is vaak omhuld door de persisterende basis van het bloemdek ... The fruit is an achene [dopvrucht] that is often enveloped by the persistent base of the androperianth [meeldraden + bloemdek], mostly calyx tube. Thus, the true fruit (mature ovary), which is often an achene, is enclosed by an outer layer that is often modified as a dispersal aid. This pome-like combination of perianth and gynoecium is known as an anthocarp [deze pitvruchtachtige combinatie van bloemdek en vruchtbeginsel staat bekend als een anthocarp] + afbeelding en als klikt op 'anthocarp' krijg je ook een doorsnede van de vrucht te zien mirabilis jalapa is een Nyctaginaceae http://botany.csdl.tamu.edu/FLORA/Wilson/tfp/car/nycpage2.ht... hier nog een afbeelding (close-up ;-) van een anthocarp: te zien bij het wikipedia artikel over mirabilis jalapa http://en.wikipedia.org/wiki/File:Seed_of_mirabilis_jalapa.J... http://en.wikipedia.org/wiki/Mirabilis_jalapa anthocarp noun a false fruit = schijnvrucht het lijkt een speciale vorm van een schijnvrucht te zijn schijnvrucht = 'pseudocarp' 'accessory fruit' 'false fruit' 'spurious fruit' (Gr. anthos: flower; karpos: fruit) A false fruit consisting of the true fruit [vrucht] and the base of the perianth [bloemdek], as in Nyctaginaceae. A fruit with some portion of the flower besides the pericarp persisting, as in a pome with the fleshy perianth tube surrounding the pericarp. A pseudocarp consisting of the true fruit and the base of the perianth. http://zipcodezoo.com/glossary/anthocarp.asp anthokarp = Frucht mit bleibender Blütenhülle z.B. bei Mirabilis http://books.google.nl/books?id=KRJfNmHhIpUC&pg=PA766&lpg=PA... Nu lijkt het echt serieus te worden Hier worden niet alleen alle vormen van anthocarps genoemd maar ook getoond What is an anthocarp? A pericarpium with attached floral parts that have undergone a marked development during post-fertilization to aid in the dissemination of the seed(s). Six basic types of anthocarps are recognized: (1) Glans—receptacle or pedicel or peduncle enlarged (2) Diclesium—calyx or hypanthium enlarged, indehiscent and dry (3) Pome—calyx or hypanthium enlarged, indehiscent and fleshy (4) Tryma—active calyx or hypanthium (5) Cypsela--hypanthium or calyx developing primarily into terminal wings or bristles (6) Anthecium—single fertile-floreted spikelet, disarticulating above the glumes The first four terms are employed in the different classes of gynoecial structures; these are exemplified as follows: Basic Types of Anthocarps According to Gynoecial Structures http://www.worldbotanical.com/fruit_types.htm -------------------------------------------------- Note added at 2 days5 hrs (2012-07-01 20:18:09 GMT) Post-grading -------------------------------------------------- Ghislaine, dit was het begin van mijn ontdekkingsreis, het antwoord op de vraag het tweede deel. Het antwoord op de vraag is dus eigenlijk de extra informatie. :-) Dit is het antwoord waarop ik het meest trots ben omdat de hele logica achter het begrip 'schijnvrucht' me duidelijk is geworden de schepping is groots |
