All cultivated pear varieties are grafted on a rootstock. The rootstock influences the tree's vigour, fruit-bearing capacity and health. Quince rootstocks are most commonly used. The type used depends on the soil, pear variety and planting system.
Solution
Knowledge of differences in rootstock properties is essential when choosing a rootstock-variety combination. It is important to choose the rootstock that suits your soil, variety choice, planting system and desired growth.
Description
The selection of the right rootstock results in a pear tree with balanced growth and production, good yields and fruit quality.
Practical recommendation
• The most frequently used rootstocks in organic pear growing are various types of quince
• The various quince rootstocks differ in vigour, requirements for soil conditions and water demands
• Not all varieties are compatible with every rootstock. Incompatibility is known for the varieties Williams, Guyot, Verdi, Bosc, Triumph de Vienne and Xenia/Oksana/Novembra. A solution is to use an intermediate stem.
• Doyenné du Comice (=Vereindechant) fits any rootstock and is, therefore good to use as an intermediate stem
• The rootstock Eline® leads to the production of pears with less bronze colour (smoother pears) than rootstocks MC, Adams, C132 and MH (Maas 2014)
• Adams is the most productive rootstock under growth conditions in which no or limited water and fertigation can be applied
• Frost sensitivity is an important factor. Quince Eline is less susceptible than other Quince rootstocks
• New rootstocks with resistance to various diseases should be tested under organic circumstances.
