To investigate the response of seedless grape to different leveles of pruning ( 20 to 200 buds! vine) C.v. Sefid, an experiment was carried out
lasting for two years during 1995-96. A complete randomized block design of
four replicates was used. The results showed that the number of buds left on the vines affected yield. The yield increased with increasing number of buds left on the vines, and the bud number was dependent upon the growth capacity of the vines. Maximum yield was obtained when 45-50 buds were left on the vines for each Kg pruning weight. According to the results, there exists
a linear relationship between trunk diameter and pruning weight.
