Effects of CO2 Enrichment on Plant Growth in Greenhouses

This review explores the positive impacts of CO2 enrichment on various plant categories, including cucumber, pot plants, cut flowers, vegetables, and forest plants. Enhanced dry weight, plant height, increased leaf numbers, and better lateral branching are noted outcomes. Additionally, plant quality in terms of growth habit and flowering is often improved under elevated CO2 levels. Rooting of cuttings benefits from high CO2 concentrations, with optimal levels recommended between 700 and 900 µmol/mol. Understanding these effects helps optimize greenhouse environments for better crop yields.

  1. Cucumber yield

  2. Pot plants, cut flowers, vegetables and forest plants show very positive effects from C02 enrichment by increased dry weight, plant height, number of leaves and lateral branching. Plant quality expressed by growth habit and number of flowers is often enhanced by C02 enrichment. The rooting of cuttings is often stimulated by high C02 levels. The optimal C02 concentration for growth and yield seems to lie between 700 and 900 HI l- I, and this C02 level is generally recommended in greenhouses. C02 concentrations higher than 1000.
