Other claims from this paper (19)
- Intervention effect Hormone sprays increased tomato plant height over control.
- Intervention effect Hormone sprays did not change tomato leaf number.
- Intervention effect Hormone sprays did not increase flowers or fruits set per cluster.
- Observation Across three clusters, gibberellin spray gave the greatest flower and fruit numbers.
- Observation Across three clusters, 2, 4-D spray gave the smallest flower and fruit numbers.
- Observation PCPA spray produced the highest fruit set percentage.
- Intervention effect Hormone sprays other than gibberellin accelerated fruit development over control.
- Intervention effect Gibberellin sprayed fruits were smaller than controls and development was checked.
- Observation 2, 4-D sprayed tomato fruits were seedless through parthenocarpy.
- Observation Gibberellin sprayed tomato fruits produced seeds.
- Observation NAA sprayed tomato fruits produced seeds.
- Association Larger seed bearing tomato fruits contained more seeds.
- Intervention effect Gibberellin spray increased tomato fruit yield over control.
- Intervention effect Other hormone sprays showed hardly any difference in tomato fruit yield.
- Intervention effect PCPA, NAA and 2, 4-D sprays increased early tomato yield.
- Observation Gibberellin spray delayed tomato harvest.
- Observation PCPA, NAA and 2, 4-D sprays decreased fruit chlorophyll and increased carotene, lycopene and xanthophyll.
- Observation Gibberellin slowed chlorophyll disappearance and lowered carotene and xanthophyll in tomato fruits.
- Observation Tomato fruit sugar increased and starch decreased during maturation, while sugar did not differ significantly among sprays and control.
