ABSTRACT:
A molded plant tray is provided in the form of a unitary molded plastic member formed of relatively light foamed plastic and having downwardly extending tapered plant cells for receiving plating medium in which individual seedlings are crown. The plastic member is provided with a plurality of parallel, U-shaped indexing rod-receiving grooves defined on the bottom surface of the plastic member by portions of the intermediate walls that define the plant cells. The indexing rod-receiving grooves are complementary in shape to a plurality of indexing rods arranged in parallel spaced relation in a drum shape rotatable about a longitudinal axis and spaced to receive the indexing rods as they rotate about the longitudinal axis. A U-shaped alignment member-receiving groove is also provided, and is defined on the bottom surface of the plastic member by portions of the intermediate walls to extend perpendicular to the central axes of the indexing rod-receiving grooves. The alignment member-receiving groove is complementary in shape to a ring extending around the perimeter of the drum shape.
