Bosc pear

' Boscs Flaschenbirne ' (synonyms: often ' Emperor Alexander ', as well as rare ' calebasse Bosc ', ' Kaiser pear ', ' Alexander pear ' and in Northern Germany ' imperial crown ') is an ancient type of pear.

History

The origin of the variety is unclear. Either she was bred by Professor van Mons in Belgium to 1807 and came from this 1810 Hadrian Diel, or she is a Zufallsämling, which was found in 1793 as a tree in Apremont.

Named Boscs Flaschenbirne after Louis Augustin Guillaume Bosc and Hadrian Diel it was called Emperor Alexander, probably by Alexander I. In the 1920s Boscs Flaschenbirne was one of three pear varieties that have been selected to kingdom fruit.

Description

Tree

The medium- fast growing tree is as high trunk and bush tree less suitable and forms - without any care or education - a broad pyramidal crown with vertical and horizontal Leittrieben side shoots from.

Fruit

The fruit is with a height of 9-11 cm and a diameter of 5-7 cm medium to large in size, and is pear - up club- or cup-shaped. The rough skin has a greenish-yellow color, which is, however, mostly russeted completely yellow-brown. The fine pulp is yellowish, sweet and sour and juicy with a fine aroma.

The fruit is used as a table or pear for preserving and is ready for picking from mid to late September / October and is - with a short shelf life - subsequently ripe enough to eat.

Others

The variety Boscs Flaschenbirne is easily confused with Princess Marianne - including the use of synonyms. Compared to this, the stem is shorter and closes without a bead on the fruit on.
