 Available rootstocks :
 - Quince of Provence (or BA29): Will produce a pear tree of medium vigor (around 3m) allowing it to be grown in an orchard as a low or medium-sized tree, but also in a trellised form (palmette, etc.). Adapted to almost all types of soil, it also has excellent resistance to the woolly aphid. It is also less sensitive to drought than the Quince of Angers.
 It bears fruit quickly (around 3 years).
 Average lifespan: 50 years.
 - Kirchensaller: A highly vigorous rootstock (6 to 8m on average) offering great adaptability to different soil types. It is more resistant to disease, drought, and cold than quince-type rootstocks and will adapt better to windy conditions due to its deep rooting. For medium and tall stems.
 Fruiting is fairly quick: 4 to 5 years.
 Lifespan: More than 100 years.
