Effects of SO/sub 2/ on growth and yield of winter crops grown in California. Research report (Final) November 1983-February 1985
The objective of the study was to ascertain the sensitivity of wheat and lettuce to SO/sub 2/ or ambient oxidants when plants are exposed under California winter conditions, the season when these crops are normally grown in California. The study was conducted in open top field chambers at the University of California, Riverside. Wheat was exposed to SO/sub 2/ or ambient oxidants for 118 days. Lettuce was exposed to SO/sub 2/ or ambient oxidants for 47 days. SO/sub 2/ at 183 and 393 micrograms/m/sup 3/ produced chlorotic injury on wheat leaves and increased total leaf sulfur. At 79 micrograms/m/sup 3/, SO/sub 2/ reduced wheat leaf buffering capacity. SO/sub 2/ at 393 micrograms/m/sup 3/ reduced total wheat seed weight by 31%. Lettuce showed no detrimental effect from SO/sub 2/.
