Abstract
Living plants, such as young, evergreen or deciduous trees or bushes, can be stored without loss of viability for several months, and cut flowers can be stored for about a week without apparent loss or freshness when enclosed in a plastic sheet or film envelope which is waterproof, excludes at least 30% of incident visible light and substantially all incident infrared radiation, and is permeable to the gaseous constituents of air, but not more permeable to gaseous oxygen, carbon dioxide, and water vapor than low-density polyethylene film having a thickness of 20 micron.
Claims12
A method of storing a living plant which comprises:
- a. enclosing said plant in an envelope of sheet material,
- 1. said envelope being permeable to not more than 30% of incident visible light, substantially impervious to infrared radiation, waterproof, permeable to the gaseous components of atmospheric air, but not substantially more permeable to gaseous oxygen, carbon dioxide, and water vapor than low-density polyethylene film having a thickness of 20 microns;
- b. storing the enclosed plant;
- c. withdrawing the stored plant from said envelope;
- and
- d. planting the withdrawn plant in soil.
A plant package comprising:
- a. an envelope of laminar sheet material,
- 1. said sheet material having an outer layer essentially consisting of synthetic resin composition and solid particles reflecting infrared radiation, and an inner layer different from said outer layer and essentially consisting of synthetic resin composition and coloring matter,
- 2. said envelope being permeable to not more than 30% of incident visible light, waterproof, permeable to the gaseous components of atmospheric air, but not substantially more permeable to gaseous oxygen, carbon dioxide, and water vapor than low-density polyethylene film having a thickness of 20 microns,
- 3. the amount of said solid particles being sufficient to make said envelope substantially impervious to infrared radiation;
- and
- b. a living plant enclosed in said envelope.
