e0“A hydroponic experiment was carried out to study the ameliorative effects of exogenous glycinebetaine (GB) upon cadmium (Cd) toxicity in cucumber seedlings”
e1“The results indicated that 50 μmol/L Cd stress decreased soil plant analysis development (SPAD) value, plant height, root length, seedling biomass, activities of ascorbate peroxidase (APX) and ATPase in leaves, stems and roots”
e3“Cd stress also elevated leaf/root malondialdehyde (MDA), proline, phenols and flavonoid content in all cucumber tissues over the control”

Other claims from this paper (15)
- Intervention effect Cadmium stress decreased SPAD value, plant height and root length of cucumber seedlings relative to control.
- Intervention effect Cadmium stress increased peroxidase and superoxide dismutase activities in all tissues of cucumber.
- Intervention effect Cadmium stress increased catalase activities in stems and roots of cucumber.
- Intervention effect Cadmium stress elevated malondialdehyde and proline in cucumber tissues relative to control.
- Intervention effect Cadmium stress elevated phenols and flavonoid content in cucumber tissues relative to control.
- Intervention effect Supplementation with GB alleviated Cd-induced growth inhibition and oxidative stress compared with Cd alone.
- Intervention effect Supplementation with GB increased SPAD value and stem ATPase compared with Cd alone.
- Intervention effect Supplementation with GB improved photosynthetic performance compared with Cd alone.
- Intervention effect External GB diminished leaf and root MDA accumulation under Cd stress.
- Intervention effect External GB decreased leaf and root proline contents under Cd stress.
- Intervention effect External GB decreased phenols and flavonoid contents in all tissues under Cd stress.
- Intervention effect Exogenous GB brought POD and SOD activities in all tissues down towards the control level.
- Intervention effect Exogenous GB brought stem and root CAT activities down towards the control level.
- Intervention effect Exogenous GB significantly increased APX activities in leaves and stems of cucumber under Cd stress.
- Mechanism The protective effect of exogenous GB against Cd toxicity in cucumber seedlings is closely related to improved photosynthesis, diminished proline and MDA accumulation, enhanced ATPase and modulated antioxidant enzymes.
