Other claims from this paper (16)
- Intervention effect High nitrogen produced larger pine seedlings than low nitrogen.
- Intervention effect High nitrogen increased residual transpiration by 11%.
- Intervention effect High nitrogen increased new root growth capacity and caused stomatal closure at higher water potential.
- Intervention effect High nitrogen increased frost damage by 24%.
- Intervention effect High nitrogen decreased plasmalemma stability to dehydration by 9%.
- Intervention effect Drought hardening decreased frost damage by 21%.
- Intervention effect Drought hardening decreased stomatal conductance by 31%.
- Intervention effect Drought hardening decreased residual transpiration by 24%.
- Intervention effect Drought hardening increased plasmalemma stability to dehydration by 8%.
- Intervention effect Drought hardening increased tissue non-structural carbohydrates and nitrogen concentration, especially with high fertilization.
- Association Frost damage was positively related to plasmalemma stability to dehydration.
- Association Frost damage and plasmalemma stability were negatively related to reducing soluble sugar concentration.
- Observation Moderate and strong drought hardening treatments did not differ.
- Intervention effect Neither nitrogen nor drought hardening clearly affected seedling performance under xeric outplanting.
- Intervention effect Fertilization increased growth under mesic outplanting.
- Intervention effect Drought hardening decreased growth under mesic outplanting.
