) blackberry plants that develop a flower shoot and fruit within several months. Cuttings would be taken during the dormant season to root, flower, and fruit for an annual high-density (≈75,000 potted plants/acre) production system that should produce ≈5000 lb

A modified culture medium is presented that promotes in vitro rooting of grapevine rootstock and Vitis vinifera L. cultivars even in the absence of plant growth regulators. Study of 15 Vitis genotypes indicated a strong genotype-dependent response to culture medium and growth regulators with respect to formation of roots in onenode shoot segments.

Knowledge concerning the lateral spread of tree root systems is important for many horticulture and silviculture objectives. Because of the hidden nature of roots, these traits are rarely studied, especially for large trees. The limited number of
