Other claims from this paper (5)
- Intervention effect Increasing available nitrogen, potassium or phosphorus singly did not counteract the pale-green colour induced by gibberellic acid in soybean.
- Observation Characteristic chlorosis of the lower leaves occurred in untreated and gibberellic acid-treated soybean plants at the low nitrogen level.
- Intervention effect Typical potassium deficiency symptoms developed only in gibberellic acid-treated soybean plants.
- Intervention effect Phosphorus amount in the tissue of gibberellic acid-treated soybean was slightly lower than in untreated plants.
- Observation The uniform pale-green colour of gibberellic acid-treated soybean was not identical to deficiency symptoms of nitrogen, potassium or phosphorus.
