Other claims from this paper (12)
- Intervention effect Both rootstocks allocated a higher proportion of biomass to roots under salt.
- Observation The 9-1-6 rootstock had lower salt sensitivity and higher salt tolerance indexes.
- Observation The 9-1-6 rootstock had a higher salt tolerance index.
- Intervention effect Salt stress significantly decreased leaf, epidermis and palisade thickness and mesophyll compactness in both rootstocks.
- Intervention effect Salt stress significantly increased sponge tissue thickness and mesophyll looseness in both rootstocks.
- Observation The anatomical change range was smaller in 9-1-6 than M. baccata.
- Association Na+ accumulation increased significantly with longer stress duration.
- Association K+ accumulation gradually decreased with longer stress duration.
- Observation The 9-1-6 stem and leaves accumulated less Na+.
- Observation The 9-1-6 stem and leaves accumulated more K+.
- Observation The 9-1-6 roots showed higher Na+ rejection.
- Mechanism The authors attribute 9-1-6 salt tolerance to root allocation and reduced Na+ transport and leaf secretion.
