Sucrose synthase (SS) was the dominant enzyme of sucrose metabolism in both stem and root vascular cambial zone tissues of nursery-grown loblolly pine (Pinrrs taeda L.) seedlings. Acid invertase (AI) and neutral invertase (NI) activities were generally less than 10% of the SS activity in both tissues. In both cambial tissues, seasonal patterns of enzyme(More)

About 95% of swamp tupelo (Nyssa sylvatica var. bi$ora (Walt.) Sarg.) and sweetgum (Liquidumbar styruci-$ua L.) seedlings survived continuous root flooding for more than two years, whereas none of the swamp chestnut oak (Quercus michauxii Nutt.) and cherrybark oak (Q. falcata var. pagodifolia Ell.) seedlings survived one year of flooding. Death of oak(More)
Two and three years after the outplanting of 1-O northern red oak (Quercus rubra, NRO) and white oak (Q. ulba, WO) nursery stocks, the highest net photosynthetic rates (A-) were observed from seedlings growing on a clearcut site followed by those under a pine stand. Both NRO and WO seedlings under a hardwood stand had A, less than 10% of the full sun(More)
Seasonal sucrose metabolism (sucrolysis) was studied in taproot cambial tissues of nursery-grown loblolly pine seedlings to assess the value of top clipping. In sucrose-importing taproots of nonclipped seedlings, sucrose synthase (SS) was the dominant enzyme for sucroti cleavage, and its activity exhibited a distinct seasonal activity. Both root SS activity(More)
We studied root and stem sucrose metabolism in trees excavated from a 9-year-old artificially regenerated lob-1011~ pine (Pinus tueda L.) plantation. Sucrose synthase (SS) activities in stem and taproot vascular cambial tissues followed similar seasonal patterns until they peaked during September. After September, stem SS activity disappeared quickly,(More)
Loblolly pine (Pinus taedu L.) seedling height, root collar diameter (RCD) and the specific activities of three sucrose metabolizing enzymes, namely, sucrose spthase (SS), acid invertase, and neutral invertase, were measured to assess seedling responses to transplant stress. Bare-root nursery-grown loblolly pine seedlings were lifted and transplanted(More)
This abstract is a prologue to this paper. Prior to his health failing, Martin Gibbs began writing remembrances of his education and beginning a science career, particularly on the peaceful uses of nuclear radiation, at the U.S. Brookhaven National Laboratory (BNL), Camp Upton, NY. Two years before his death Martin provided one of us (Govindjee) a draft(More)
