Effects of Ethylene on Development and Field Performance of Loblolly Pine Seedlings
Ethylene, a plant growth regulator, was produced by loblolly pine (Pinus taeda L.) seedlings in cold storage. Production was cyclic, with a peak occurring that seemed associated with seedling dormancy. Higher than naturally occurring levels of ethylene stimulated root growth potential, bud activity, survival, and growth. However, the intermediate concentrations that were measured in the cyclic peaks had an inhibiting effect on seedling development and performance. Further research is needed to assess the economical significance of these cyclic concentrations on survival and growth.
