Abstract:
The activities of nitrate reductase and glutamine synthetase in leaves of greenhouse grown rose plants (Rosa hybrida cvs. Ilseta and Mercedes) grafted on various rootstocks were compared with those in leaves of non-grafted, own-root plants of these cultivars. The results obtained showed that the enzymatic activities as well as nitrate content in the leaves were altered by the grafting and by type of the rootstock used. These rootstock-imposed alterations differed between the two cultivars used in the study.
