Wax Extracted from Waste Cauliflower Leaves Shows Potential Antitranspirant Efficacy When Applied to Rapeseed Plants
Abstract
:1. Introduction
- To extract wax using supercritical CO2 from cauliflower (Brassica oleracea L.) leaf waste and to formulate the wax for spraying as a film antitranspirant.
- To evaluate the efficacy of this wax formulation in comparison with a current commercial film antitranspirant (di-1-p-menthene) for reducing stomatal conductance and water use of young glasshouse-grown plants of rapeseed (Brassica napus L.) in three experiments.
- To compare the cost of the extracted wax with the cost of di-1-p-menthene.
2. Materials and Methods
2.1. Supercritical CO2 Extraction of Wax and Its Characterization
2.2. Plant Material and Experimental Design
2.3. Water Management and Treatment Application
2.4. Physiological Assessments
2.5. Statistical Analysis
3. Results
4. Discussion
- Another plant component co-extracted with the wax may have had antitranspirant activity, e.g., if abscisic acid was co-extracted, as this hormone is a metabolic antitranspirant [3].
