Abstract
Inoculation with a culture of Puccinia recondita resulted in a susceptible infection type (IT) on Thatcher, a moderately resistant IT on Lrl6, and a highly resistant IT on Lr\9.The apparent photosynthetic rate (APR) and stomatal conductance were determined on days 0,4, 6, 8, 12, 15, and 20 after inoculation.Significant reductions in APR were detected 8 days after inoculation of Thatcher and the line containing Lrl6.Differences between healthy and P. recondita inoculated plants increased on each date of measurement until day 20 after inoculation when the APR of infected plants of Thatcher and those containing Lr 16 was reduced to about 56% of healthy.There were no significant differences between healthy plants and plants carrying Lr 19 following inoculation with P. recondita for any sampling date.This demonstrated t he value of resistance to P. recondita.The numbers of uredia cm" 2 were significantly negatively correlated with APR on day 20 after inoculation for Thatcher and the Lr 16 line.At day 20 the average stomatal conductance for both Thatcher and the Lrl6 line was significantly less than that of the healthy controls.
