D1 Week 1 - Multiple Choice Revision Questions Flashcards
Increased levels of bud fruitfulness in next year’s growing season is influenced by what?
- The emergence of the inflorescences after bud burst and their success depends on air temperatures above 10ºC
- As the flowers open prior to fertilisation; the success depends on air temperatures above 16°C
- The exposure of compound buds to sunshine in the previous year’s growing season.
- The fertilisation of the ovules and its success depends on dry conditions.
The exposure of compound buds to sunshine in the previous year’s growing season.
What are compound buds?
* Buds that break in the same year as they are formed.
* Buds that develop into tendrils only
* buds that never break but stay dormant
* Buds that break the following spring
Buds that break the following spring
They are also referred to as latent buds.
How can rainfall affect the growing vine and ripening grapes?
- Prior to harvest can cause berry splitting
- Ensures good fruit set
- Decreases the risk of fungal diseases
- Warms the mesoclimate
Prior to harvest can cause berry splitting
In the warmer wine regions in the EU zones of production which of the following is correct?
- Minimum potential alcohol increases, level to which must can be enriched decreases, deacidification becomes illegal and acidification becomes legal.
- Minimum potential alcohol decreases, level to which must can be enriched decreases, deacidification becomes legal and acidification becomes illegal.
- Minimum potential alcohol decreases, level to which must can be enriched decreases, deacidification becomes illegal and acidification becomes legal.
- Minimum potential alcohol increases, level to which must can be enriched increases, deacidification becomes illegal and acidification becomes legal.
- Minimum potential alcohol increases,
- level to which must can be enriched decreases,
- deacidification becomes illegal and acidification becomes legal.
Which acid is typically high in grapes ripened in very cool conditions?
* Citric acid
* Malic acid
* Lactic acid
* Ascorbic acid
Malic acid
Where are anthocyanins generally found in the grape berry?
* The stems
* The skins
* The pulp
* The seeds
The skins
What are the limits to the accuracy of the growing degree days system?
* It does not work when temperature is measured in degrees Fahrenheit.
* Vine growth slows down significantly when temperatures go above 33ºC, high temperatures influence the rate of photosynthesis; this is not taken into consideration in this calculation.
* The minimum temperature for vine growth is not considered.
* The growing season calculation is too short.
Vine growth slows down significantly when temperatures go above 33ºC, high temperatures influence the rate of photosynthesis; this is not taken into consideration in this calculation.
What is a key advantage of clonal selection over mass selection?
* It is a quicker process to create a new clone
* The quality of fruit is higher
* It is a cheaper process to create a new clone
* The new plants created are virus free
The new plants created are virus free
What are the main characteristics of a Mediterranean climate?
* Minimal temperature variation during the year so seasons are not so defined, only by rainfall.
* Wide annual range of temperatures (hot summers and cold winters) with low rainfall during the growing season.
* Low annual range of temperatures (warm summers and mild winters) and relatively high rainfall during the growing season.
* Low annual range of temperatures (warm summers and mild winters) with most of the rainfall during the winter months.
Low annual range of temperatures (warm summers and mild winters) with most of the rainfall during the winter months.
Which vine organs are principally responsible for photosynthesis?
- Roots
- Petioles
- Buds
- Leaves
Leaves
What rootstock parentage is resistant to root-knot nematode e.g. Ramsey?
- V. champini
- V. rupestris
- V. riparia
- V. berlandieri
V. champini
What would be considered the main disadvantage of planting a vineyard close to a body of water?
* It can increase the temperature of the vineyard by reflecting the sun’s rays.
* Increases the risk of fungal diseases.
* Soils close to bodies of water tend to have poor drainage.
* Increases the risk of ground frost.
Increases the risk of fungal diseases.
Humidity is generally higher and therefore fungal diseases become a greater risk in vineyards close to bodies of water.
You are asked to evaluate a new vineyard site in the Middle Mosel that is going be planted with Riesling to produce high quality wine.
Which of the following points should you consider?
- The aspect of the slope
- The risk of erosion
- The proximity to the river
- The viability of mechanisation
All
In high pH soils which trace element’s uptake is inhibited by the vine increasing the risk of chlorosis?
* Sulfur
* Aluminium
* Potassium
* Iron
Iron
Which of the following will NOT improve soil structure?
- Adding nutrients
- Encouraging the biodiversity of the soil
- Repeatedly cultivating the soil
- Adding organic matter
Adding nutrients
Adding nutrients will not improve the soil structure but the addition is beneficial for nutrient poor soils.
