| Abstract | Paclobutrazol was applied at several rates as a foliar spray to nursery grown loblolly pine seedlings. Paclobutrazol significantly reduced (P<0.05) seedling height without reducing root collar diameter. Seedling heights were reduced by up to 20% depending on rate of paclobutrazol applied. Shorter seedlings may be more tolerant to desiccating environments and drought. Paclobutrazol was applied as a foliar dip to nursery run (1-0) loblolly pine seedlings at the rates of 500, 250, 125, 62.5, 31.25, and 0 ppm. Paclobutrazol at the rate of 125 ppm significantly increased (P<0.05) root growth potential (RGP). Compared to the control, total number of new roots was increased by 88% without reducing shoot growth. Increasing loblolly pine root growth with paclobutrazol may be important for improving plantation establishment, especially on harsh sites. |
