 | | We studied a broad range of CO2 atmospheric environments to ascertain the influence of CO2 on immature pine tree seedling growth and secondary metabolism in order to develop a technique to improve pine growth in a nursery environment. |
 | | Loblolly pine (Pinus taeda L.) of Pinaceae, an important paper tree in Southeastern United States, was employed in this study. |
 | | Loblolly pine seedling fresh weights, number of roots, shoot length, and number of needles from pine seedlings supplemented with 10,000 umol mol**-1 CO2 increased 120%, 171%, 36%, and 245%, respectively, when compared to loblolly pine seedling grown without any CO2 enrichment. |
