Carbon Dioxide Enrichment during Photoautotrophic Micropropagation of Protea cynaroides L. Plantlets Improves In Vitro Growth, Net Photosynthetic Rate, and Acclimatization

Abstract: The effects of CO2 enrichment on the in vitro growth and acclimatization of Protea cynaroides L. plantlets were investigated. Three CO2 enrichment concentrations were used: 0 (control), 1000, 5000, and 10000 μmol·mol−1. Plantlets in the control treatment were cultured on half-strength Murashige and Skoog (MS) medium supplemented with sucrose, whereas those enriched with different CO2 concentra… Show more

“…We found CeLn, CeLn, and CeLs increased dry weight accumulation in shoots and roots, which agrees with the result of Fierro et al (1994), but they also shifted dry weight to the roots, resulting in a higher root-toshoot ratio compared with CaLn. This result is consistent with the effects of CO 2 enrichment in grape (Wu and Lin, 2013) and in Rhodes grass (Ksiksi and Youssef, 2010), indicating supplementary light and CO 2 enrichment may promote the uptake of nutrients from culture substrate by altering the distribution of dry weight and thus increasing yields.…”

“…However, there was an increase compared to the fresh weight at the beginning of the study. Fresh weight was the accumulation of photosynthate and water content (Wu and Lin, 2013). The sunlight, water, and nutrients affected the photosynthate and water content (Febriyono et al, 2017).…”
