Title
The effect of soil moisture stress on growth and flowering of carnations
Kowalczyk, Richard Adam Digital Collections of Colorado (Colorado State University) 1967. doi:10.25675/3.025142
Other claims from this paper (11)
- Intervention effect Reducing soil depth from 8 to 4 inches increased problems of too much or insufficient water for carnations.
- Intervention effect Carnation yield and grade were best when plants were grown in 8-inch soil.
- Intervention effect Raw field soil decreased carnation yield in a greenhouse bench because of an aeration problem.
- Intervention effect High soil moisture stress delayed the flowering of the second crop of carnations by up to 5 weeks.
- Association The number of stomatal and epidermal cells per unit area increased as soil moisture stress increased.
- Intervention effect Leaves of plants grown under high stress had greater resistance to transpiration.
- Association The correlation between transpiration rate and stomatal aperture was higher than that between transpiration rate and solar radiation.
- Observation The lithium chloride hygrometer was not sensitive enough to indicate when to water carnations in a greenhouse.
- Observation Measuring stomatal apertures with silicon rubber impressions was too laborious for a practical field technique.
- Observation The stomatal index was not beneficial for understanding stomatal distribution in carnations.
- Observation Bulk density, moisture content at all suctions and total pore space of the best soils were an average of the extremes of all soils compared.
