AbstractMaximum emergence occurred when honey mesquite (Prosopis glandulosa Torr, var. glandulosa) seeds were planted 0.5 cm deep at a soil temperature of 27 C. Percent emergence was severely reduced at a soil temperature of 18 C, regardless of planting depth. Seeds placed on the soil surface germinated, but seedlings did not survive. Seeds planted 5 to 6 cm deep germinated, but no seedlings emerged. Rate and extent of emergence in a nursery were evidently dependent on the temperature reaching 24 C in the surface 2.5 cm of soil.
