| Abstract: | Applications of ultrahigh CO2 treatments accelerated cuphea (Cuphea viscosissima × C. lanceolata ‘PSR23’) growth and development and aided in seedling establishment. The growth (fresh weight) and morphogenesis (number of leaves and roots and seedling length) were determined in cuphea seedlings exposed to 350, 1500, 3000, 10,000, or 30,000 μmol mol−1 CO2 for 30 days under greenhouse conditions. Greater CO2 levels, especially the ultrahigh levels (i.e. ≥3000 μmol mol−1 CO2) resulted in significantly higher (P ≤ 0.05) fresh weights, leaf numbers, root numbers, and seedling lengths compared to seedlings grown under ambient air (350 μmol mol−1 CO2). For example, cuphea ‘PSR23’ Morris heavy seedlings showed the greatest seedling fresh weight, leaf number, root number, and seedling length when supplemented with 10,000 μmol mol−1 CO2 increasing 607%, 184%, 784%, and 175%, respectively, when compared to seedlings grown without CO2 enrichment. |
