Abstract

The effects of root-inducing substances and time intervals were studied on the rooting of grape cuttings of Florida Selection 1001 left in sand beds 6, 8, and 10 weeks. Observations were made on the number of rooted cuttings, and the number and length of roots per cutting. The major results were as follows: 1. Root-inducing substances had no significant effect on the rooting percentage of grape cuttings. 2. The time the cuttings remained in the sand beds did have highly significant effects on the rooting percentages and on the number and length of roots per cutting, regardless of hormone treatments. 3. In these respects the 10-week period was better than the 6- or 8-week periods. 4. Indolebutyric acid had the greatest effect on the number of roots produced by grape cuttings, which is of importance in the establishment of these cuttings.
