Propagation of Aspen Trees from Lateral Roots
Lateral roots were used successfully in propagating aspen trees under greenhouse conditions. Roots ½ to ¾ inches in diameter and 1 to 15 inches in length were the most desirable sizes. All monthly collections of roots were satisfactory but the earliest sampling was best. Relative location of the lateral root from tree proper was not a factor in shoot production. A sand or sand-soil medium plus a nutrient solution, gave best results. Lateral roots, freshly collected, gave good growth of shoots and roots; 8 months of storage reduced viability, while 15 months of storage gave no growth at all. Results indicated that aspen trees can be produced easily and in quantity.
