Other claims from this paper (10)
- Intervention effect Ca at 0.8 μM reduced root growth of peach seedlings.
- Intervention effect Ca at 0.8 μM made roots brown, gelatinous and decayed before foliar Ca deficiency symptoms developed.
- Intervention effect Ca at 0.8 μM caused peach leaves to wilt severely within 24 hours.
- Intervention effect Ca at 0.8 μM made peach seedlings begin to defoliate 5 days after treatment started.
- Intervention effect Ca at 2.5 μM caused Ca deficiency symptoms in leaves as marginal chlorosis followed by necrosis.
- Intervention effect Ca at 2.5 μM made roots die back severely with little regrowth.
- Intervention effect Ca at 2.5 μM restricted elongation of main and secondary roots, which were swollen and stubby.
- Intervention effect Ca above 7.5 μM produced no Ca deficiency symptoms in peach seedlings.
- Observation The Ca concentration in the external solution increased from 0.8 μM to 4.5 μM.
- Observation Shoot tips died on some peach seedlings.
