Other claims from this paper (11)
- Observation Total nitrogen in buds, bark and stem wood increased markedly in autumn.
- Observation Total nitrogen in winter buds and stems remained almost unchanged after leaf abscission until bud break.
- Observation Total nitrogen in burst buds increased drastically during new growth.
- Observation Total nitrogen in stems decreased markedly during bud burst.
- Observation Free arginine in stem bark accumulated in autumn in parallel with total nitrogen accumulation in buds and stems.
- Observation Proline accumulated in wood, bark and buds starting in October.
- Observation Proline in bark and wood decreased significantly at the early stage of bud break.
- Observation Arginine in stem bark decreased slightly at the early stage of bud break.
- Observation Asparagine, aspartic acid and glutamic acid increased appreciably in buds and stems.
- Observation Proline and arginine increased in dormancy-releasing buds before bud break.
- Mechanism Decrease in total nitrogen and increase in asparagine in stems and sprouting buds were primarily due to breakdown of protein stored in stems.
