what is stage 3 of grape growth and ripening? - ANSWER--
ripening
what happens during grape ripening? - ANSWER--- cells expand
rapidly
- sugar and water accumulate

what is stage 4 of grape growth and ripening? - ANSWER--extra
ripening
what happens during stage 4 of grape growth and ripening? -
ANSWER--- No more sugar or water are imported to the grape by
the phloem at this stage, but water loss in the grape through
grape transpiration means that sugars are concentrated
- Extra-ripe aromas can also develop
what is the ideal temp range for fruit set? - ANSWER--26-32C
what factors affect temp and sunshine levels? - ANSWER---
latitude
- altitude (& diurnal range)
- slope, aspect
- proximity to water
- wind
- soil characteristics

Generally, the vine needs a minimum of ______ mm of rainfall per
year in cool climates and at least ______ mm in warm regions -
ANSWER--500
750
what does water do for vines? - ANSWER--- provides turgidity
- photosynthesis
- temp regulation
- acts as a solvent for nutrients in the soil
- medium in which all of the vine's biochemical and physiological
mechanisms take place
lack of water resulting in closing of stomata can have what effects
on vines? - ANSWER--- help conserve water
- reduce or stop photosynthesis (lack of CO2 entering vines)
- slows growth and ripening
