| The present investigation was undertaken to determine if CO2 enrichment promoted rooting and subsequent growth of Lagerstroemia indica L. cuttings. Cutting were taken from the one-year-old semihardwood twigs, and rooted in enclosed propagation frame with enriched CO2 levels (500-2000ppm) regulated by a gas monitor. The base of each cutting was dippid from 500 to 4000ppm naphthalenacetic acid. Roothing was determined after 3 months. CO2 enrichment during roothing increased the rooting percentage and number of roots per cutting, but nontreated cuttings rooted in low percentages producing one or two roots. The length of new shoots and dry weight of whole cuttings in CO2 enrichment were significantly greater than those of the atmospheric controls. The organic and inorganic compounds concentraion were measured as an indication of nutritional state in whole cuttings. As a result of CO2 enrichment, carbohydrate, protein and inorganic compounds(total nitrogen, P2O5, K2O, CaO, MgO) concentration were higher than controls. |
