Description

Germination energy of cottonwood seed decreased gradually as moisture stress increased from 0.0 to 10.0 atm; 15.0 atm inhibited germination except at 32 and 38 C. Temperature extremes of 15 and 38 C drastically reduced germination energy, and the reductive effect of 38 C was particularly marked after storage. Only 15-atm moisture stress or 15 C greatly reduced total germination. Germination under optimum conditions (27-32 C) was reduced from 90% to 69% by 12 months' storage. Little seedling growth took place at stresses above 5 atm and at temperatures of 15 and 38 C. Initial growth was related to seed size, which varied considerably with parent tree.
