摘要:
The influence of soil moisture on endomycorrhizal infection in black walnut was studied using four groups of potted seedlings watered at different time intervals. Seedlings watered every day or every second day had much longer lateral roots but fewer infected root segments than seedlings watered every third or fourth day. These results suggest that controlling the soil moisture level may alter the conditions that affect competition for colonization between introduced and indigenous mycorrhizal fungi.
