Title: Growth and Production of ´Bing` and ´Schmidt` Sweet Cherries on Several MXM or East Malling Cherry Rootstocks
Authors: F.E. Larsen, S.S. Higgins and V.S. McCamant
Abstract:
'Schmidt' and 'Bing' sweet cherries were
planted in 1982 at the Washington State University Royal Slope Research Unit near Othello,
WA. 'Bing' was grafted onto EMCR (East Malling
cherry rootstocks) 15, 16, 21, 38, and 50.
'Schmidt' was grafted onto Mazzard seedling
and onto M×M (Mahaleb × Mazzard) rootstocks
14, 39, and 97. Data on growth and production
are reported for the first 8 years of commercial
production. 'Bing' trees were largest on
EMCR.38 and were smallest on EMCR.50.
Rootstock had no significant effect on cumulative yield of 'Bing,' which averaged 203 kg tree-1
after 8 years.
Cumulative yield efficiency for
'Bing' was highest from trees on EMCR.16 or
EMCR.50, and was lowest from trees on
EMCR.15 or EMCB.38. The largest 'Schmidt'
trees were on Mazzard seedling rootstock, and
the smallest were on M×M.14 or M×M.97. Rootstock
had no significant effect on cumulative
yield of 'Schmidt,' which after 8 years averaged
66 kg tree-1, and had no effect on cumulative
yield efficiency.
All tested M×M. rootstocks
offered some degree of size control, relative to
'Schmidt'/Mazzard seedling, but productivity
of 'Schmidt' was low.
