PERFORMANCE
◉Rootstocks resistant to root-knot nematodes. Answer: Ramsey and
Dog Ridge (both vitis champini)
◉Rootstocks resistant to draught. Answer: 110 R(ichter), 140
R(uggeri)
hybrids of v. rupestris and v. berlandieri
they root deeply and quickly
◉Rootstocks tolerant to waterlogged soils (high rainfall/soils
retaining water). Answer: v. riparia (Riparia Gloire)
◉Rootstocks tolerant to salinity in soils. Answer: 1103 Paulsen
◉Rootstocks tolerant to acidic soils. Answer: 99 Richter
110 Richter
hybrids of v. rupetris and v. berlandieri
,◉Main grape varieties. Answer: vitis vinifera (native to Eurasia)
Vitis Riparia
v. Berlandieri
v. rupestris
above mainly used for rootstocks
◉Anatomy of the vine: main elements. Answer: roots
permanent wood (trunk)
one year old wood
main shoots
◉Structure of the shoots. Answer: Main shoots
the stem

◉Vine propagation. Answer: 1. Cutting - allows usage of rootstocks,
can be treated for disease
2. Layering - burying a cane and cutting it off once it establishes
root; cannot be grafted
◉Why use different clones?. Answer: yields
berry size
resistance to disease
skin thickness
◉Mass selection (Selection Massale). Answer: growers cultivate
their own cuttings
expensive and labor intensive, takes a long time
