This rootstock, reproduced exclusively by seeding, is obtained by the self-fertilization of the strain SL 405 AF FERCI. It can be classified in the range of semi-robust to robust and allows for a more opened port to grafted varieties with lighter foliage than those grafted on SL 64.
Fruit set is rapid and abundant while maintaining a good fruit caliber, even slightly superior to witness (SL 64 / COLT). High productivity index.
PONTALEB® is adapted to and recommended for dry and calciferous soils and we can see in certain conditions, a better tolerance to root asphyxia than with classic Mahalebs.
Apart from its simple reproductive system, PONTALEB® has excellent agronomic returns. This is a good selection of SAINTE LUCIE DE SEMIS.
