Summer and winter survival of Puccinia recondita and infection by soilborne urediniospores
Hassan, Z.M.
Summer and winter survival of Puccinia recondita and infection by soilborne urediniospores - 1986 - Printed
Tables, references p. 371-372
Emerging wheat seedlings readily trapped urediospores of P. recondita from soil or host plant debris. Soilborne spores survived simulated summer temp. of 34/22øC day/night for up to 22 d on moist soil, 13 d on dry soil and 4-7 d when covered with a 5 mm layer of soil. Trapped spores survived 8 d on dry leaves at 34/22ø. Spores in pustules on excised leaves placed on soil during simulated summer (30-33ø) conditions survived up to 15 d. Spores floating on flood waters were able to cause infection when brought in contact with partially submerged host leaves. Dormant mycelium survived all conditions that host tissue could survive.
