Chapter 1: The Vine Flashcards
Canopy
The main shoots and all of their major structures: stems, buds, leaves, lateral shoots, tendrils, inflorescences, grape bunches
Clonal Selection
Nurseries identify vines with positive mutations, takes cuttings to grow new vines (1 vine can provide a large number of mutations)
Cross
Two parent vines from the same species
Cross Fertilization
Pollen from stamens of flower of one vine transferred to flowers of another vine
Desuckering
Process of removing lateral shoots (especially off the trunk)
Hybrid
Two parent vines from different species
Inflorescence
A cluster of flowers on a stem which becomes a bunch of grapes at fruitset
Internodes
The parts of the main axis between the nodes
Lateral shoots
The parts of the main axis between the nodes
Lateral shoots
Grow from prompt buds formed in same year
Lignify
Green shoots become woody, rigid and brown at which point they are called canes
Mass Selection
Owners take cuttings from vines in their own vineyard and cultive these cuttings (can also send them to a nursery to get them grafted onto American rootstock); cuttings taken from several different vines; these vines are monitored for several years to ensure they are the best
Nodes
Little swellings along the main shoot
Petiole
Leaf stalk
Prompt buds
Form and break open the same growing season; form on primary shoot,; form lateral shoots
Prompt shoots
Form and break open in the same growing season; form on primary shoot (that has just grown from a compound but) and produces lateral shoots
Solutes
Substances that dissolve in a liquid to form a solution; the shoot’s main access transport sugars and minerals in water
Stomata
Pores on the underside of leaves letting CO2 in and water out; close if water stress
Teinturier
A grape with a red coloured pulp; not common; Alicante Bouschet is an example
Transpiration
Process whereby water and nutrients are drawn from the soil up through the vine to the leaves
