Gas Comments
GAS: Effect of Ethylene on Plants Indoors Gas ranges in the home may produce ethylene to injure opening buds; natural gas contains no ethylene but the burners on starting, for 17 seconds, and on stopping, for ten seconds, emit small amounts especially if they are automatically controlled. A67-901 0
GAS: Toxicity to Plants Natural gas from heaters presents no ethylene problem but manufactured gas carries it and is very toxic. A71-783 0
