Correlative Effects of Bench Chip Budded 'Mirandy' Roses.
by Yui-Sing Faon, and Fred T. Davies, Jr.
Bench Chip budding was tested as an alternative to T-budding of roses in field bush production. Greater than 90% success was obtained when 'Mirandy' scions (Rosa hybrida L.) were bench chip budded to rooted 'Brooks 56' R. multiflora Thumb. rootstocks with a Liliput budding tool. Growth of chip budded scions was inhibited by the presence of rootstock lateral shoots. This correlative inhibition was overcome by selected forcing, girdling, and pruning treatments to promote vigorous scion growth. Best chip growth was obtained when scions were budded onto the same side as rootstock lateral shoots and rootstock stems were partially cut or girdled. A positive correlation existed between 'Mirandy' scion shoot growth and flowering.
