Ethylene Accumulation during Cold Storage of Pine Seedlings: I.s it a Problem?

Ethylene is a plant growth regulator that can inhibit root and shoot growth in plants. The atmospheres of two loblolly pine seedling cold storage facilities were sampled over a three month period during the winter of 1981-1982 to determine the extent of ethylene accumulation. Ethylene concentration reached physiologically significant levels (2300 ppb) in the storage facility which employed open seedling bales. The use of K-P bags for seedling packaging in the other facility precluded the accumulation of ethylene in the atmosphere during storage. There was evidence of ethylene addition by the operation of gasoline-powered forklifts in one of the storage facilities. Gas samples from within seedling bales and K-P bags indicate that loblolly pine seedlings do produce ethylene.
