Cellular Drought Tolerance Studies in Loblolly Pine

Drought resistance evaluation and selection in woody, perennial plants often takes several years. Tissue culture technology is being explored as a means of accelerating the selection and tree improvement process and understanding the physiological basis of drought tolerance. The physiological, tolerance response of osmotic adjustment has been demonstrated in vivo and in vitro in a large number of plants. In loblolly pine ( Pinus taeda L.), it has been demonstrated only in vivo.
