CHERRY ROOTSTOCKS

MAHALEP SL 64
– It is among the clone rootstocks belonging to the Mahalep species.
– It is a medium-strength rootstock that develops at a rate of 75-80 times that of the Mahalep seedling.
– It is not recommended for heavy, high groundwater, clayey soils.
– It does not need support because its root system is well-developed and its hold on the soil is strong.
– In gardens to be established on this rootstock, 5m between rows and 3.5-4m on rows are suitable.
– If a cherry orchard is to be established on soils where lime is a problem, this rootstock can be used.

GISEL A ROOTSTOCKS
– They are rootstocks that were found by hybridizing P. Avium P. Canensis species as a result of breeding studies conducted at the Gissen Research Institute in Germany.
– Gisel A 5, Gisel A 6, Gisel A 7, Gisel A 12 are the most commonly used Gisel A rootstocks and in recent years the fully dwarf Gisel A 3 rootstock has also started to be used.
– Gisel A rootstocks should be used in deep soils with a pH below 8 and an active lime rate of less than 10% and with irrigation possibilities.
– Gisel A rootstocks are not suitable for heavy-textured soils with high groundwater.
– Gisel A rootstocks should not be used in extremely hot regions.
– The most dwarf of these rootstocks is Gisel A 3 and 35-45% of the rootstock formed by Mazzart rootstock (bird cherry) is Gisel A 5 rootstock; 50-55% of it is Gisel A 6 rootstock, 70-80% of it is Gisel A 12 rootstock, 90-95% of it is Gisel A rootstock.
– Gisel A rootstocks provide 2-3 years of earliness compared to Mazzart seedling rootstock.
– Gisel A 5 and Gisel A rootstocks are tolerant to Prune Dwarf virus and Chlorotic Necrotic Ring Spot virus diseases.
– When cherry trees are replanted on Gisel A 5 rootstocks where the cherry tree is removed, problems occur in the trees.
– Since there is excessive fruit formation on Gisel A rootstocks from self-fertile varieties, the fruits remain small. For this reason, gardens should not be established with saplings hung on Gisel A rootstocks, especially varieties such as Sweet Heart, Lapins and Chelan.
– Gisel A 5 rootstock can be planted at 4x 2.5 Gisel A 6 rootstock can be planted at 4.5x 3.5 intervals and distances.

MAX MA DELBARD ROOTSTOCKS
– It was found as a random seedling in the US state of Oregon.
– The most important of the Mazard and Mahalep hybrid Max Ma rootstocks is the Max Ma 14 rootstock, and there are Max Ma 60 and Max Ma 90 rootstocks besides this rootstock.
– MaxMa14 rootstock is semi-dwarf and carries the good characteristics of Mazard and Mahalep rootstocks.
– It creates a tree crown volume of 70-75% of the bird cherry (Mazard) rootstock.
– It makes the variety on it bear fruit early. It has a positive effect on fruit size and quality. .
– It can make very few bottom shoots.
– MaxMa rootstocks are resistant to Pseudomonas disease.
– They are cold-resistant rootstocks.
– They are not recommended for heavy-textured, poorly drained soils.
– They are widely used especially in Spain and France.

CAB ROOTSTOCKS
– They were improved at the University of Bologna in Italy.
– CAB 4D, CAB 11E and CAB 6P are the most important rootstocks in this series.
– They are in the Prunus Cerasus (Cherry) species and can be recommended as rootstocks for cherries.
– They have been tested and widely used in Italy for 30 years.
– They can be used in heavy-textured soils.
– They form trees as much as 50-60% of the tree volume formed by bird cherry and develop with the same strength as Ma x Ma 14 rootstock.
– It yields 2 years earlier than the variety on the seedling.
– It forms a few shoots at the base, and it is difficult to propagate with cuttings.
– It is a rootstock resistant to cold.

P-HL ROOTSTOCKS
– The most important of these rootstocks obtained by hybridizing Prunus Cerasus and Prunus Avium species in Czechoslovakia are P-HL-A, P-HL-B and P-HL-C rootstocks.
– It has a shallow root system.
– It is resistant to cold climate conditions.
– It can be produced by tissue culture.
– Of the rootstocks in this group, P-HL-C rootstock has the feature of being the dwarfest rootstock, and produces trees that are 40-50% larger than the standard seedling rootstock of bird cherry.
– A support system is necessary in windy areas.
– Partially resistant to heavy textured soils.

WEIROOT ROOTSTOCKS
– It is one of the cherry rootstocks developed from the Prunus cerasus species in Germany.
– The most important ones are Weiroot-158 and Weiroot-54 rootstocks.
– It ensures that the variety on it bears fruit early.
– It forms trees that are 40-45% larger than the crown formed by the bird cherry seedling rootstock.

VICTOR ROOTSTOCK
– It is a rootstock improved at the University of Bologna in Italy.
– It is among the semi-dwarf rootstocks.
– It was obtained from the Prunus Cerasus species.
– It is a good rootstock in terms of fruit size and productivity.
– It is moderately resistant to lime, groundwater and drought.
– On this rootstock, 3-3.5 m spacing and distances within the row and 4-4.5 m between the rows can be applied.
