Other claims from this paper (8)
- Intervention effect Shoot apex excision had almost no effect on plant nitrogen content.
- Intervention effect Shoot apex excision sharply increased nicotine concentration, especially in middle and upper leaves.
- Intervention effect Axillary bud removal increased nicotine concentration further.
- Intervention effect Routine leaf harvest wounding did not change leaf nicotine concentration.
- Intervention effect Reducing leaf harvest times did not change leaf nicotine concentration.
- Association The results indicated no direct relationship between nitrogen supply and leaf nicotine concentration.
- Intervention effect Applying 1-naphthylacetic acid after apex removal decreased total plant nicotine.
- Mechanism Reduced auxin supply after apex removal may regulate root nicotine synthesis.
