Isozyme Polymorphism during Rooting at Elevated CO2

Year: 1989

Type: article

Abstract: The effects of CO 2 enrichment and IAA on adventitious root formation of hypocotyl cuttings of Impatiens balsamina L. ‘Camellia’ were examined. Root numbers increased significantly at 675 and 1000 µl CO 2 /liter compared to 350 µl liter -1 . In the presence of IAA, the number of roots increased at 675 and 1000 µl CO 2 /liter and the effect was most pronounced with 5 µg IAA/ml at 675 µl CO 2 /liter. IAA-treated cuttings, compared to those in deionized water, exhibited slightly increased intensities of some of the isoperoxidases coinciding with root initiation and development in a CO 2 -enriched atmosphere. The data also indicate that at least two isozymes of peroxidase are associated with root development. Chemical names used: l- H -indole-3-acetic acid (IAA).
