Abstract
Effect of root type and clone of ‘Schattenmorelle’ sour cherry trees upon growth and productivity was studied in the years 1993–1996. Self-rooted trees of ‘Schattenmorelle’ clone 226/80 showed a lower vigour compared with trees on rootstocks.
It was manifested by a significantly reduced increase of trunk cross section area (TCSA) in successive biennial periods and over the whole experiment.
After eight years of study the size of self-rooted trees (expressed as TCSA) was 39 – 55 % smaller, compared with the trees on rootstocks.
Yield per tree and cropping efficiency index were affected by the type of root system, except for the year 1994 when no significant differences in yield per tree were found.
In the last four years (1993 – 1996) self-rooted trees gave a lower yield per tree; however, their cropping efficiency index was 23 – 28 % higher than that of trees grown on seedling rootstocks.
It is concluded that self-rooted ‘Schattenmorelle’ cherry trees are more compact than trees on Pr. avium rootstocks and hence may be planted denser, resulting in a higher production per unit area.
Between two clones of ‘Schattenmorelle’ no differences in growth and yield indices were found, except for cropping efficiency index for the period 1995–96 which was higher for clone 226/80 than for 226.
