Other claims from this paper (10)
- Observation Parthenocarpy was induced in Flame Tokay and Rose Muscat.
- Observation Post-bloom BA plus KGA3 produced the most pronounced parthenocarpic berry growth.
- Observation Post-bloom 4CPA also produced pronounced parthenocarpic berry growth.
- Observation Post-bloom KGA3 at 50 to 100 ppm produced parthenocarpic berries.
- Observation BA alone had only a slight effect on parthenocarpic berry development.
- Observation BA with gibberellin or auxins gave satisfactory parthenocarpy results.
- Intervention effect BA plus KGA3 increased berry number and cluster weight.
- Observation At bloom, BA plus KGA3 gave Rose Muscat clusters with practically all berries seedless.
- Intervention effect Treated clusters produced 501 parthenocarpic berries, 96%, versus 14% berries in controls.
- Intervention effect BA with auxin or gibberellin produced seedless berries smaller than seeded berries in untreated clusters.
