Effects of CO₂on greenhouse grown eggplant (Solanum melongenaL.) II. Leaf tip chlorosis and fruit production

Research note: Can decreased transpiration limit plant nitrogen acquisition in elevated CO2?

“…Russell and Barber 1960;Nye and Tinker 1977;Mortensen 1987;Masle et al 1992;Nederhoff and Buitelaar 1992;Pons and Bergkotte 1996;Polley et al 1999), and numerous authors have discussed (but not assessed) its possible role in plant nutritional changes under CO 2 enrichment (e.g. Mortensen 1987;Nederhoff and Buitelaar 1992;Conroy and Hocking 1993;Geiger et al 1999;Rogers et al 1999;Stitt and Krapp 1999;BassiriRad et al 2001). …”

Energy Gain in Passive Solar Greenhouses Due to CO2 Enrichment

“…Other studies present even higher yields for specific crops along with the CO 2 ; for example, tomato crops had a production increase ranging from 30% to 70% [4][5][6][7][8]. Similar behavior is presented by pepper and aubergine cultivation [8][9][10], and also other works referring to cucumber cultivation showed a production increase of between 25% and 50% [8,[11][12][13]. For floriculture plants, the benefit of CO 2 enrichment is reflected mainly in the quality amelioration [14][15][16][17].All the crops mentioned above, as with most of those cultivated in greenhouses, belong to the category of C3 plants which grow under optimum day temperatures ranging from 16 • C to 25 • C, and at night from 14 • C to 18 • C [18]; this emphasizes the necessity of daytime cooling and overnight heating be taken into consideration and the awareness that the most favorable periods for the cultivation of greenhouse crops are the spring and autumn.…”
