Other claims from this paper (11)
- Intervention effect A regulated level of pruning did not entirely overcome the low-yielding tendencies of very vigorous grafted vines.
- Observation The heaviest-yielding vines over six years were on the V. Champini selection Salt Creek.
- Observation Vines on the V. Champini selection Salt Creek showed the best balance between growth and fruit production.
- Intervention effect Girdling during bloom markedly increased total carbohydrate content in the shoots.
- Intervention effect Girdling during bloom decreased total nitrogen level in the shoots.
- Intervention effect Girdling increased yields only of the vigorous vines on Dogridge.
- Intervention effect Topping the vine at bloom did not change carbohydrate levels in the shoots at berry shatter.
- Intervention effect Topping the vine at bloom gave some reduction in vine vigor.
- Intervention effect A foliar spray of maleic hydrazide at 500 ppm during bloom was not effective in changing nutrient levels in the shoots.
- Observation Maleic hydrazide was followed by evident leaf symptoms late in the growing season.
- Observation Maleic hydrazide was followed by a reduction in shoot elongation late in the growing season.
