| Popis: | A technique was developed for controlled micro-release of CO2 into the leaf canopy of strawberry and tomato plants under field production conditions; The leaf canopy atmosphere of tomato plants was enriched to 500 and 1200 ppm CO2 with release rates of 60 and 300 l/h·30 m of row respectively. After 60 days of enrichment for 6 h each day beginning at fruit set, the total shoot biomass and yield was increased 41% and 25 % respectively for the high CO2 release rate. Strawberry leaf canopies did not show increased CO levels with CO2 enrichment except under ventilated2 row-covers where the atmospheric CO2 level was increased to 1500 ppm CO2. Although the total biomass was increased 39% this did not translate into increased yields perhaps due to excessive temperatures under the row covers. |
