Herregård
20 prøver af Quercus sp., er undersøgt. 12 prøver er dateret. Seks af prøverne havde splintved bevaret, heraf én med fuld splint. Yder mere kunne der konstateres splintvedgrænse på to prøver og én prøve havde et løst splintstykke, som ikke kunne placeres.

Prøverne blev udtaget fem forskellige steder i husets nordfløj. Tagkonstruktion, øst-ende; Tagkonstruktion, vest-ende; Loft, 1. etage; Loft, stueetagen samt Bjælker i kælder.

Tagkonstruktion, øst-ende
Seks prøver, alle dateret. Én af prøverne har splintved bevaret (21300069). Yngste bevarede splintårring er dannet i 1517. Kompenseres der for manglende splintved kan fældningstidspunktet for træet, der har leveret tømmer til prøven, beregnes til ca. 1534.
Prøverne, repræsenteret af 21300029, 21300039 og 21300059, stammer muligvis fra en senere reparation. Yngste bevarede årring dannet i 1527. Kompenseres der for manglende splintved, kan det beregnes at træerne, der har leveret tømmer til prøverne, er fældet ca. 1547.

Tagkonstruktion, vest-ende
Seks prøver, hvoraf fem er dateret. Kurverne fra 4 af de daterede prøver (21300079, 21300089, 21300119 og 21300129) synkroniserer indbyrdes. Yngste bevarede årring, som er dannet i 1529 (21300129) har barkkant, og er fældet i vækstperioden maj - september (sommerfældning). Alle fire træer, der har leveret tømmer til prøverne, er givetvis fældet 1529.
Kurven fra prøve 21300099 dækker perioden 1481-1523. Prøven har splintved bevaret og fældningstidspunktet for træet, som prøven stammer fra, kan beregnes til ca. 1540.

Samlet, viser undersøgelsen, at tagkonstruktionen over både øst- og vest-enden kan være bygget samtidigt; ca. 1529-34 og repareret i 1540'erne.

Loft, 1. etage
Fire prøver, én er dateret (21300139). Kurven fra prøven synkroniser med det øvrige daterede materiale fra undersøgelsen. Yngste bevarede årring dannet i 1511. Kompenseres der for manglende splintved, kan det beregnes, at træet, der har leveret tømmer til prøven, er fældet efter ca. 1531.
Konstruktionen af loftet på 1. etage kan ikke dateres nærmere end til efter ca. 1531.

Loft, Stueetagen
To prøver, ingen dateret. For få årringe.

Bjælker i Kælder
To prøver, ingen dateret. For få årringe.

Til dateringen af prøverne er der brugt referencekurver fra Danmark, Tyskland og Sydvestsverige.

Splintstatistik: 20 -5/+10 år.

English summary:

VEDBYGÅRD, RUDS VEDBY, HOLBÆK AMT

Manor house
20 samples of Quercus sp., oak, were examined. 12 samples are dated. Six of the samples had sapwood preserved of which one had complete sapwood. Sapwood border was observed on two samples and one sample had a small bit of sapwood, which had become detached and could not be refitted to the rest of the sample.

The samples come from five different locations in the north wing of the house. Roof, east end; Roof, west end; Ceiling, 1^st Floor; Ceiling, Ground floor and Beams from Cellar.

Roof, east end
Six samples were examined, all are dated. One of the samples had sapwood preserved (21300069). The outermost preserved tree-ring was formed in AD 1517. Allowing for missing sapwood, the felling date, for the tree, from which the sample comes, can be estimated to c. AD 1534.
The samples represented by 21300029, 21300039 and 21300059 possibly come from a later repair. The outermost preserved tree-ring was formed in AD 1527. Allowing for missing sapwood, the felling date, for the trees from which the samples come, can be estimated to c. AD 1547.

Roof, west end
Six samples were examined, of which five are dated. The curves from four of the dated samples (21300079, 21300089, 21300119 and 21300129) cross-match internally. The outermost tree-ring, which was formed in AD 1529 (21300129) has bark edge, and is felled in the growing season May - September (summer felling). All four trees, from which the samples come, are probably felled in AD 1529.
The curve from sample 21300099 covers the period AD 1481-1523. The sample has sapwood preserved and the felling date for the tree, from which the sample comes, can be estimated to c. AD 1540.

As a whole, the analysis shows that the roof over the east and west ends, possibly were constructed at the same time; c. 1529-34 and repaired in the 1540's.

Ceiling, 1^st Floor
Four samples were examined, of which one is dated (21300139). The curve from the sample cross-matches with the curves from the other dated samples. The outermost tree-ring was formed in AD 1511. Allowing for missing sapwood, the felling date for tree, from which the sample comes, is estimated to after c. AD 1531.

The construction of the ceiling on the first floor cannot be dated more precisely than to after c. AD 1531.

Ceiling, Ground floor
Two samples, none were dated. Too few tree-rings.

Beams from Cellar
Two samples, none were dated. Too few tree-rings.

In dating the samples, reference chronologies from Denmark, Germany and south-west Sweden were used.

Sapwood statistic: 20 -5/+10 years.
