'_ PEACH YIELDS, PRINCETON, 1951
is W. D. Armstrong
The subzero weather of early February 1951 killed virtu-
ally all peach fruit buds in orchards over the commercial sections
of Kentucky except ina few spots in Western Kentucky. The peach
variety orchard at the Western Kentucky Experiment Substation
zs at Princeton came through withacrop on some of the hardier va-
le rieties.
W
?$ Of the varieties that fruited, the following produced a full
°S crop: Mamie Ross, Veteran, Cumberland, and Triogem.
ie
sh Varieties that produced a medium to partial crop(enough to
St spray and care for) were Halehaven, Marigold, Alton, Vedette,
in Viceroy, Dr. Burton, Ideal, Georgia Belle, Hiley, Summercrest,
S' July Heath, Erly Red Fre, Barbara, and K-53.
Those produc_ing only an occasional peach (1 to 10) were
lg Sunhigh, Golden East, Fair Beauty, Golden Beauty, Golden Jubilee,
a` Fisher, Lizzie, White Hale,Ambergem, Afterglow, Nectar, Sni-
dl der Elberta, Elberta, Redhaven,Eclipse, Dixired, and Raritan
Rose.
le Varieties that had absolutely no fruit in 1951 on mature
an trees were: Gage, Prairie Schooner, Prarie Clipper, Prarie
ig Rambler, Golden Gem, Short, Tena, and July Elberta.
CONCORD GRAPE VINES RESIST SUB-ZERO WEATHER
is W. D. Armstrong
al
During February 1951 temperatures of approximately Z5
degrees below zero occurred in the grape-variety planting at the
Q- Western Kentucky Experiment Substation at Princeton. These
ie temperatures killed to the ground the vines of most varieties.
However, all the vine of Concord, the standard black grape of the
East survived along with their canes (last year‘s growth). A1-
though there was heavy bud killing at the nodes {joints)on the Con-
cord canes, enough buds grew and set fruit to produce a crop of
near-normal size. Only about 30 percent of the joints produced
new growth; however, as the vines were not pruned there was a
large expanse of 1950 canes from which new growth originated.
3; Canes of the Fredonia variety, an outstanding new, early
Jn ripening black variety also survived and had enough live buds to
produce a partial crop on unpruned vines. Other varieties, of
less interest in Kentucky, that withstood the cold weather and pro-
is duced a partial crop were Caco, Van Buren, Norton, and West-
Er field. Varieties that were killed to the ground, however, grew
sprouts from the roots, and new vines could be rebuilt from these
in two or three seasons.
