Conversion of rootstock cane buds into vegetative character ones
  • The problem to be solved:
    To increase the percentual take efficiency of the grafting by converting the mixed buds of the rootstock cane into vegetative character ones.
  • Definition:
    The buds of the rootstock cane are mixed character ones since they contain both shoot and cluster rudiments, too. The joining of the graft is indirect, the components are joined by the callus. Without callus (healing-tissue) there is no graft union. The callus formation is not satisfactory on the shoot pole. The cluster rudiments encumber the callus formation, so as it is practical to convert the buds into vegetative character ones. The invented method solves this problem as a result of some 40 years of experiments.
  • Presentation:
    In case of green grafting the percentual take efficiency can be as high as 100%, while in case of wood-grafting it is only 40% or, at best, 55%. It turned out that in case of green grafting the parts to be joined have vegetative character - because of the cluster rudiments are grown later in the buds during the summer season - but in case of bench grafting during the winter season there are always cluster rudiments in the buds of the parts to be joined that encumber the callus formation on the shoot pole. The higher is the number of cluster rudiments in the buds the lower is the rate of callus formation on the shoot pole. By decreasing the number of cluster rudiments in the buds the rate of callus formation becomes increased in a manner that in case of no cluster rudiments at all in the buds a fully all-round callusing can be achieved on the shoot pole. By this way, a nearly 100% of take efficiency may be obtained with a perfectly all-round graft union.
    The task is to increase the rate of callus formation on the shoot pole of the rootstock cane, since the callus formation is always satisfactory on the root pole. This is why it was necessary to discover the possibilities of the increase of callus formation rate. To achieve this increase it is necessary to decrease or completely encumber the cluster rudiment formation in the buds of the rootstock cane. This effect can be achieved by absorbing a part of the colour components of the daylight spectrum during the growth of the rootstock cane. The effect of the remaining colour components encumber or decrease the cluster rudiment formation and provide a perfect vegetative growth. The experimentally obtained results are self-explanatory ones and, it turned out that the callus formation rate has been increased significantly on the shoot pole of the rootstock cane, due to the used masked light treatment method, in comparison to the control-sample grown under natural daylight.
  • Application: First of all, it can advantageously be used in the propagation wood production.
  • Advantages:
    Using this method an all-round or closely circular callus formation can be achieved on the shoot pole instead of the incomplete callusing obtained up to now. This means that the graft union can also be an all-round one. Consequently, a nearly 100% of take efficiency can also be achieved.
  • Stage of development:
    The experiment has been carried out using two methods. On one hand, the rootstock cane has been grown under transparent masking colour foil. On the other hand and, due to the fact that the growth under transparent foil is more expensive and laborious, the light masking has also been tested using a colour spray but, due to the lower masking effect the results were something moderate. In 2000 further tests will be carried out. The rootstock canes grown in 1999 will be grafted in 2000. The results will be available by autumn. The documents are available.
