Drought Effects on Adventitious Root Development in Blue Grama Seedlings
Briske DD and Wilson AM. 1980. Drought Effects on Adventitious Root Development in Blue Grama Seedlings. Journal of Range Management. 33(5):323-327
Crowns of blue grama (_Bouteloua gracilis_) seedlings of three ages were exposed to drought treatments for 2 days, in constant humidity environments, and were then planted in moist soil for a 10-day growth test at 25 degrees C. Percentage survival of crowns decreased with a decrease in water potential during the temporary drought treatment and with a decrease in crown age at time of treatment. The percentage survival rates of 21-, 28-, and 35-day-old crowns treated at -180 bars were 5, 54, and 83 respectively. Crowns exposed to the 2-day drought treatment subsequently produced shorter adventitious roots than untreated crowns. Thus, a drought-induced inhibition of adventitious root growth may reduce the probability of successful seedling establishment.
