The Right Rootstock for a Good Graft Stick
Propagation by grafting is expensive in terms of resources and labour input and is justified only because of the potential for enhanced returns for the finished, often highly desirable, plant. Failure of grafts can therefore be very costly and must be avoided.
Use of the correct understock is fundamental to success but there is such a confusing range of terminology applied to planting stock that while propagators know the size and type of stock required, they cannot be certain of asking for it correctly, let alone receiving it. There is, therefore, a need for a
simplified and generally accepted specification for stocks and planting material. The aim of this short paper is to address some of the misunderstandings current within the trade and to propose the adoption of specifications and definitions already used in forestry.
