摘要

Leaf indole content and vigour were studied in trees of 4 cherry rootstocks grafted with the scion cultivars Van and Germersdorfi orias and in cuttings taken from mother stock trees of the rootstocks. Leaf indole content of the high-vigour Prunus mahaleb rootstock Sainte Lucie 64 (SL64) was the lowest, at 2-4 mg/100 g, while Colt had 5 times this amount. The semi-dwarfing or dwarfing MXM 14 and MXM 97 rootstocks had 6-7 times more indole in their leaves than SL64. Leaf indole content in the scion cultivars was about 10 times higher than that of SL64, and was higher in the lower-vigour cultivar Van. The leaf indole content of cherry scion cultivars of the same age grafted on rootstocks with differences in vigour (of significantly different size) did not show any differences attributable to the rootstock. Rootstocks differing in vigour did not appear to affect the leaf indole content of the scions grafted onto them. Accepting that there is a positive relationship between the indole content in youngleaves and plant indole-auxin content, this indicates that differences in the content of indole-auxins cannot be responsible for the differences in vigour.
