Abstract |
Jet star, an indeterminant tomato cultivar, was exposed to 0.011, 0.059, 0.118, 0.235, and 0.468 ppm SO2 in open-top field chambers supplied with nonfiltered(NF) air and to 0.005, 0.113, and 0.466 ppm SO2 in chambers with charcoal-filtered(CF) air. Treatments were given 5 hr/day, 5 days/wk, for a total of 57 days during July, August, and September. Ripe fruit yields were decreased 16% by O3 in NF compared with CF air. The highest dose of SO2 given in CF air reduced fruit yield by 18%. Ambient O3 and the SO2 treatments were additive in their effects on fruit yields. Significant reductions in fruit numbers were observed. Fruit quality was not measurably altered. A negative linear response for ripe fruit yield vs SO2 exposure dose was demonstrated. |
