Viticulture Terms Flashcards
1
Q
débourrement
A
budburst, budbreak
- 1st new green tissue emerges from each bud
2
Q
millerandage
A
hens and chicks
- Grape clusters with berries that vary in size and number of seeds
- Caused by cold weather at flowering, mineral deficiency, or disease
- Results in reduced yields and uneven ripening
3
Q
taille
A
pruning
- Excess wood is removed from the dormant vine, strategically leaving only buds that will produce
4
Q
porte-greffe
A
rootstock
- portion of the vine in contact with the soil
- typically phylloxera resistant
5
Q
couloure
A
uneven set
- Occurs when a significant number of berries do not set after flowering
- Caused by cold weather during flowering or mineral deficiency
- Results in reduced yields
6
Q
inflorescence
A
Cluster of flowers that, after berry set, becomes a grape cluster
7
Q
shot berries
A
Small, hard, green berries that contain no seeds
8
Q
suckering
A
Removing small, unwanted shoots that grow from buds, not yet developed, on the trunk and cordon
9
Q
Vitis berlandieri
A
- Species of grape commonly used for rootstock
- Good for limestone soils but does not graft well
10
Q
Vitis riparia
A
- Species of grape commonly used for rootstock
- Tolerates wet soils
- Has a devigorating (slowing of shoot elongation) effect on the vine
- Induces early ripening
11
Q
shoot devigoration
A
natural slowing of shoot elongation
usually due to water stress
