Cane Quality Determination of 5 BB and 140 Ru Grape Rootstocks

摘要

This study was conducted to investigate best cane quality level in 140 Ru and 5 BB grape rootstocks through morphological changes when the canes were sectioned into 4-bud segments from base to tip. Canes were later forced to grow in plastic pots to determine the relationship between cane quality and root-shoot growth characteristics. The results suggested that rootstocks differ along their canes length for best quality to use in propagation. Cuttings should be prepared in 5 BB between 5 to 16(th) internodes, and in 140 Ru between 5-12(th) nodes, because of better quality and well balanced root-shoot growth.
