Gisela 6, supports medium density plantations 450-550 trees / ha. Medium vigor, Gisela®6, begins to produce in 2-3 years, reaches full production on 5
In this article we will present the most representative characteristics of the Gisela 6 rootstock.
Gisela 6 is a variety of acid cherry (wild cherry) obtained by Doctor Gruppe in Giessen (Germany). Its obtaining was made thanks to the crossing of the subspecies Prunus cerasus (wild cherry) x Prunus Canescens (Gray leaf cherry or Cano cherry). Disseminated in 1994, this rootstock is currently under patent or commercial registration.
Characteristics of the Gisela 6 cherry rootstock
Vigor: Gisela 6, has a vigor greater than Gisela 5 medium-high, 70-90% according to the sources consulted. When the land is poor and we graft varieties of high productive capacity, vigor decreases to levels below 50%.
Productivity: Certain studies show a significant improvement in the precocity and production of Gisela 6 compared to the Mazzard rootstock. With productions similar and even superior to Gisela 5.
Compatibility. It is compatible with other varieties of sour or sour cherry and with the majority of existing sweet cherry varieties.
Density: Plantations of between 450 and 550 Gisela 6 plants can be made per hectare. For cherry plantations made in Vogel central leader, it supports 6×3 meters and 6×4 meters frames in Steep Leader.
Resistance: It is resistant to gill nematodes. It is moderately resistant to agrobacterium (bacteria that produces tuberculosis) and the parasitic fungus Armillaria.
Root: The Gisela 6 rootstock has medium anchorage to the ground and does not produce sierpes or little grandparents.
Soil: It adapts well to all types of soils, however, its planting is preferable in fertile soils. The rootstock does not favor acid soils.
Propagation: Gisela 6 is easier to spread than Gisela 5 by being able to multiply both by semi-woody and in vitro stapling. Therefore, the nursery sale prices should be somewhat lower.
Fruit quality: Due to its high production capacity, the size of the cherries on Gisela 6, can be significantly diminished. Especially, if the cherry tree pruning is not carried out with adequate intensity.
Irrigation: Keeping plants in a good water state is essential. By requiring less intensive planting frameworks, Gisela 6 has access to a greater amount of water resources from the rain, requiring a lower amount of irrigation compared to Gisela 5.
Pruning: In productive plantations with Gisela 6 rootstocks, it is essential to carry out “aggressive” pruning regulators. Thus, better control of tree size is achieved, and the probability of overload is eliminated.
Climate: The Gisela 6 rootstock withstands well arid or hot climates.
We must use the Gisela-6 rootstock in medium density plantations and preferably when we want to plant varieties of cherry that are not very productive or difficult to curdle. It is a good rootstock for fertile soils.
