Talk:Vitis

Cleanup

The article is full of typos despite being well-written. I suspect a copyvio typed in from an offline source, but am I jumping to conclusions? I didn't find hits putting a few phrases into Google or Google Scholar. Should we try to investigate, just start over, or what? Kingdon 11:53, 26 August 2007 (UTC)

Either way, the article needs a major rewrite, which would probably automatically solve any possible copyright problems. I would also argue that Vitis should be a disambiguation page, rather than lead directly to an article about a small town in Austria. If anything it should be the other way around; "Vitis" should lead to the plant genus as it is a well-known and economically important plant, whereas the Austrian town is probably unknown to anybody outside Austria.

I did some very basic cleanup, moved the article about the Austrian town to Vitis (town) and turned Vitis into a disambig page. I tried to move Vitis (genus) to Vitis as the grape genus is far better-known than the town because of its economic importance, but apparently because Vitis was originally an article about the town, I couldn't make the move.

I've merged in a load of stuff that didn't belong in the grape article - it's still a mess, but at least it's started to go in the right direction. I filled the taxobox with the list of species from the grape article - looking more closely, it's got some of the hybrids like labruscana in there which presumably would be better off in the main text?

Rome

"Vītis" is the name of the staff carried by Centurions. I would appreciate if someone made note of this in the article. —Preceding unsigned comment added by 70.49.59.214 (talk) 15:09, 27 May 2009 (UTC)

No, you either have to create an article on this type of staff and add it to the hatnote, or create a disambiguation page for Vitis. This article is on the plant genus. Tomas e (talk) 16:45, 27 May 2009 (UTC)

question placed in article main space-moved to talk.

I observed that theese "species" can be "hibridized" (f.e.: vinifera x lambrusca), and the "hibrids" are able to producing seeds, and theese seeds can germinate. This is contrastant with the definition of different spesie!

Sure that my experience is not sufficient, I explane two situations:

1. Baco 22A is a crossing between Folle Blanche (vinifera) x Noah, but Noah is an hibrid of lambrusca and riparia (about this look baco 22A) Consequentially: lambrusca and riparia are two different subspecies of an only specie.

2. Frontenac is (lambrusca x vinifera) x riparia (List of grape varieties), so I understand that lambrusca and vinifera are an only specie.

From the (1.) and (2.) I can tell that is vinifera, lambrusca and riparia appartain to an only specie, so their correct names are Vitis vinifera vinifera, Vitis viniefra lambrusca and Vitis vinifera riparia, according to the only name that I've found on "Il Nuovo Pokorny", "Zanichelli Edizioni".

Many plant hybrids produce fertile offspring and many hydrides can also be crossed with other hybrids and produce fertile progeny too; thus using this criteria to destinate a group of plants as the same species is not reliable. It is more important for some plant species to see how consistent the progeny are before one can make that determination, if the progeny of a cross are distinctive from the parents, then the parents are very likely distantly related and not the same species.

The definition of a species is a big can of worms (see species problem). Using the definition of "groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups", the question is not whether they can hybridize (or whether they do occasionally), but whether they do so often enough to form an interbreeding population (this is very much a capsule summary and especially in plants the situation of who is breeding with who and where the genes are flowing can get complicated pretty fast. And that's just natural populations - cultivated plants are a whole different thing). Kingdon (talk) 01:37, 17 October 2009 (UTC)

I'll also point to it:Specie (for Sandro.maoret (talk · contribs), who asked for explanations in Italian). Kingdon (talk) 01:54, 17 October 2009 (UTC)

Juice?

The article says, Approximately 71% of world grape production is used for wine, 27% as fresh fruit, and 2% as dried fruit. So where does grape juice come from? Toadstools? --jpgordon^{::==( o )} 20:45, 8 September 2011 (UTC)

parts of the grapevine

I'm trying to find the name of the thing on a grape vine that's really thin and wraps it's self around things to hold on and climb things I can't find this anywhere. Should there be a section explaining the parts of a plant?50.47.100.224 (talk) 17:39, 29 October 2012 (UTC)

How long

How long before a plant yields fruit ? And how long does it live ? TIA, --Jerome Potts (talk) 03:53, 11 October 2017 (UTC)

Newly planted vines yield fruit in the 2nd season, according to this university source. Once growing and yielding fruit, annual fruiting begins about a month (in May) after the first flowers in the northern hemisphere, according to this. WP has an article on Annual growth cycle of grapevines and Old vine which provides sources showing some European vines about 350 years old are still bearing fruit. --Zefr (talk) 04:47, 11 October 2017 (UTC)
