Abstract

The budding of drupe fruit trees is more difficult than that of pone fruit trees. In this group of trees the tissues grow together slowly and often fail to unite. The results obtained in nurseries are often insatisfactory. Among the drupe fruit trees grown in Poland sour cherry is moist worthy of note because of insufficient supply of the nursery material of this species. It was why investigation was undertaken on the reasons of failures in budding sour cherry trees as well as on the ways of stimulating the union of the scion with the root stock. The investigation was carried out in 1971-1974 in the Agricultural Experimental Station of the Agricultural Academy in Krakow, the cultivar English Morello budded on Cerasus avium being the object. All experiments were carried out in a randomized block design in 5 replications, 30 root stocks being a plot. The experiment included the following fac¬tors as influencing the processes of budding and growth of young trees: I/ Tying, defoliation, and budding 30-40 cm above ground on shoots of the current season's growth, II/ Foliar nutrition of root stocks and parent trees with urea and IS-24 chelate, III/ Spraying root stocks and parent trees with solutions of giberellin and indoleacetio acids, IV/ Treating the trunk of the root stock with solutions of giberellin, indoleacetic, and indolebutyric acids and of etephon budding, V/ Short time grafting of scions on agar media with indoleacetic acid and then inserting the scion with small amount of the medium in the cutting on the stock. It was found that spraying the parent trees or root stocks with the giberellin acid negatively influenced as well the growth of the scion tissue in the root stock as the percentage of successful budding. Spraying scions with a 100-ppm solution of the giberellin acid resulted in a 30 % decrease in the number of successul budding, while spraying root stocks decreased this number by 17 %. Under the influence of the giberellin acid the leaf stems separated earlier thus this influence was contrary to that of the indoleacetic acid. If the leaf stems keep long it may in a greater degree suggest suc cessful budding than if they separate. As the shoots of drupe fruit trees grow older, the ability of the tissues to grow together decreases. If the site of budding is moved on the growth of current season, not only the number of successful graftings but also the total mass of the young tree are increased in consequence of limited pruning of the root stock. With this method of budding the number of successful grafting increased by 10 % and the thickness and height of young trees were significantly greater than in other treatments The plastic band used for tying was found better than the raffia, the number of positive budding increasing by 7 %. The defoliation and ring barking has a marked negative influence on the percentage of positive budding, while the effect of foliar nutrition was insignificant. The insertion of an agar medium between the scion and root stock did not negatively influence the growing of tissues in the process of budding. An addition of the indoleacetic acid /at the concentration of 1 and 0,1 ppm/ increased the percentage of unions between the cambium of the root stock and that of the scion. Rains significantly influenced the results of budding, better results being obtained if greater rains were noted in the period when the scion grew to the stock.
