Macadamia growers (especially those who are new to Macadamia farming) often question the differences between the root systems of vegetative clonal rooted-cuttings (VPs) versus seedling rootstocks. The answer is simple; VPs will produce a more even orchard due to the consistency of genetics and they offer a superior root-system when propagated by superior nurseries with experience.
It is true that not all cultivars root well on their own rootstocks in which case either a seedling or a clonal rootstock is required for grafting.
Amorentia customers give consistent feedback confirming what is already known at Amorentia – their Beaumont VPs are of excellent quality and show evidence of high yield early because they are well rooted and because their genetic material is superior.
High yielding nursery trees come from excellent mother-material.
Through its Plant-Improvement Scheme, the Amorentia Macadamia Nursery Beaumont mother-trees, (as well as all other cultivars) were monitored for high performance over a 15 year period. This exercise ensured that only high yielding trees remain in the mother-blocks. This was achieved by weighing the nuts from each mother-tree and removing all poor performing trees. It means that the genetic material used for all propagation at Amorentia offers growers a high-yield potential from day 1. It also means that the Nursery has 100% control over their propagation procedures.
