The wild grape Vitis mustangensis comes from North America with many varieties and subspecies. It was first described by George Engelmann in 1845 . In 1861 it was described as Vitis mustangensis by the biologist Samuel Buckley .
distribution
The vine is native to the US states of Arkansas , Louisiana , Oklahoma , Texas and northern Mexico . The Arkansas River forms the northern limit of the range. In some sources the states Mississippi , Alabama and Florida are also mentioned.
description
Vitis mustangensis has felty, white shoot tips with reddish edges. The leaf shape varies widely, but is usually thick and soft with a shiny, waxy surface. The leaves are dark green with convex leaf teeth. The red inflorescences are very small. This wild species, which climbs ten to 13 m high, has small, loosely-berried grapes with medium-sized berries. The deep dark blue berries have gelatinous flesh that has a burning, bitter taste.
use
The wild grape is very productive. However , the berry is unsuitable for viticulture . According to reports by pioneers of the 19th century the wine was palatable when the Most about 3 kg of sugar per gallon enclosed with the wine and incurred with alcohol aufspritete.
It has good resistance to downy mildew and powdery mildew , phylloxera , drought, soils with a high salt content and nematodes . On the other hand, it is very susceptible to excessive lime content in the soil and to frost. It is also very difficult to root.
Several crosses with the wild vines Vitis rupestris , Vitis riparia and Vitis berlandieri are known. The poor rooting makes it practically impossible to use it as a rootstock . At Davis University of California , selections of the species Vitis champinii ( Vitis mustangensis × Vitis rupestris ) are made because of their high salt and nematode resistance. These are used to a limited extent as rootstocks in Australia and California.
