Contrary to previous indications, this study shows that there is no inherent limit to the longevity of seminal roots of blue grama seedlings. When restricted to seminal primary roots, blue grama seedlings grew actively in the greenhouse for 22 weeks. Tillering began at 3 weeks and continued at a linear rate of 0.165 tillers per day. Leaf length on primary shoots reached a maximum of about 80 cm at 6 to 7 weeks and decreased by death of older leaves thereafter. Total leaf length of tillers reached a maximum of 250 to 350 cm of green tissue at 13 to 14 weeks. The water-transport capacity of the subcoleoptile internode apparently prevented further leaf expansion. Since field conditions impose sudden increases in transpirational stress, it may be necessary to restrict leaf expansion until adventitious roots are well established.Type
