Abstract
New sweet cherry (Prunus avium L.) orchards are planted at high tree densities using precocious size-controlling rootstocks to improve economic returns and labor efficiency. Growers are seeking alternative planting strategies to reduce high costs of establishing these systems. This research project evaluated the feasibility of a sleeping eye (dormant graft) planting system compared to the traditional nursery tree (two year grown) for multiple genotypes. Graft survival and growth data were collected in 2006 and 2007 for 'Bing', 'Chelan', and 'Tieton' grafted on Mazzard (P. avium L.), MxM® 60 (P. avium x P. Mahaleb), and Gisela®6 (P. cerasus x P. canescens) in 2006. Graft success was 24% greater for nursery trees vs. sleeping eyes. In 2006 the nursery trees were larger than the transplanted sleeping eye trees but in 2007 growth of sleeping eye trees exceeded that of the transplanted nursery trees. Tree growth was delayed in the first orchard year irrespective of planting system. Using virus-infected budwood reduced graft success significantly but did not affect tree vigor. Preliminary economic comparisons suggest that start up costs for a two acre sleeping eye block would be $1,865 to $1,092 less than costs for planting standard nursery trees.
