Other claims from this paper (12)
- Intervention effect Brown greenhouse shelters significantly reduced stem, leaf and root development.
- Intervention effect Clear greenhouse shelters significantly reduced stem, leaf and root development.
- Intervention effect Clear-shelter seedlings grew taller than controls but none supported themselves after shelter removal.
- Mechanism Brown-shelter growth reduction was attributed to 80% lower PAR.
- Intervention effect Brown field shelters had 55% mortality versus 60% without shelters.
- Intervention effect Clear field shelters had 40% mortality versus 60% without shelters.
- Mechanism Most clear-shelter field seedlings could not support themselves because height growth exceeded stem development.
- Observation Half of clear-shelter seedlings experienced new growth dieback in a warm early season.
- Observation Wire-shelter seedlings were unsupported, exposed to wind and ambient temperatures.
- Observation Wire-shelter seedlings had the lowest mortality, 20%, and supported themselves.
- Intervention effect Wire-shelter seedlings were significantly shorter than clear- and brown-shelter seedlings.
- Recommendation Wire shelters are a promising alternative for self-supporting seedlings with comparable growth, greater survival and similar cost.
