A Precision Seed Sower for Longleaf Pine Bareroot Nursery Seedlings

Commercial vacuum precision seed sowers were modified to obtain satisfactory density, row alignment, and spacing of longleaf pine (Pinus palustris Mill.) seed in two southern bareroot forest tree nurseries. Satisfactory seedling density and spacing for production of topquality seedlings can be obtained with the modified sower if seed purity is at least 95 % and germination potential is at least 70%. Potential limiting factors encountered and suggestions for improvements are discussed. Tree Planters' Notes 41(4):33-38; 1990.
