Other claims from this paper (19)

Intervention effect Hormone sprays increased tomato plant height.
Intervention effect Hormone sprays did not change tomato leaf number.
Intervention effect Gibberellin produced the largest total number of tomato flowers and fruits set.
Intervention effect 2, 4-D produced the smallest total number of tomato flowers and fruits set.
Intervention effect PCPA gave the highest tomato fruit set coefficient.
Intervention effect Hormones other than gibberellin accelerated tomato fruit development versus control.
Intervention effect Gibberellin reduced tomato fruit size versus control.
Intervention effect PCPA produced seedless tomato fruits.
Intervention effect 2, 4-D produced seedless tomato fruits.
Intervention effect Gibberellin produced seed containing tomato fruits.
Intervention effect NAA produced seed containing tomato fruits.
Association Larger seed containing tomato fruits had more seeds.
Intervention effect Gibberellin increased tomato fruit yield over control.
Intervention effect PCPA increased early tomato yield.
Intervention effect 2, 4-D increased early tomato yield.
Intervention effect PCPA, NAA and 2, 4-D lowered fruit chlorophyll and raised carotene, lycopene and xanthophyll.
Intervention effect Gibberellin delayed chlorophyll disappearance and lowered carotene and xanthophyll versus control.
Intervention effect Hormone sprays did not significantly change fruit sugar content versus control.
Observation Tomato fruit starch content declined with maturation in all plots.
