Other claims from this paper (11)
- Intervention effect Alkali stress reduced linseed relative growth rate much more than osmotic or salt stress.
- Association Relative growth rate of linseed decreased as osmotic potential decreased.
- Intervention effect Photosynthetic activity and pigment indices of linseed were nearly unchanged with increasing osmotic and salt stresses.
- Intervention effect Alkali stress severely inhibited photosynthetic activity and pigment indices of linseed compared with osmotic and salt stresses.
- Mechanism Alkali stress may decrease photosynthetic pigments in linseed through Na+ uptake accumulation to toxic levels.
- Mechanism Massive Na+ influx may be the main cause of damage from alkali stress in linseed.
- Mechanism Alkali-stress precipitation of phosphate and metal ions causes a sharp decrease in ionic activity in linseed.
- Mechanism Proline synthesis decreased osmotic potential in linseed under stress.
- Mechanism Proline in linseed remedied the shortage of inorganic anions and maintained stability of the intracellular pH.
- Observation Betaine contributed little to osmotic adjustment in linseed because its ratio to total organic matter was very low.
- Mechanism Accumulation of organic acids may maintain ionic balance in linseed under alkali stress.
