Studying the effect of the method of budding protection on the survival and development of scions of sweet orange (Citrus sinensis L.) and limequat (Fortunella Japonica × Citrus Aurantiifolia)

Citrus fruits are the world’s leading fruit crops. To meet the growing demand and increase the area under these crops, it is necessary to produce high quality planting material. The main method of producing seedlings of cultivated citrus varieties is budding. When using this technique, it is necessary to ensure reliable protection of the joint of the components. There is a lack of information on this issue in the literature. The present study was conducted in the suburb of Jalalabad, Nangarhar, Afghanistan, at a modern nursery. The first experiment (Citrus sinensis L.) included the following variants: 1. binding the scions with polyethylene tape without covering the buds; 2. binding the scions with polyethylene tape covering the buds; 3. binding the scions with polyethylene tape without covering the buds + painting the binding with white paint; 4. binding the scions with polyethylene tape covering the buds + painting the binding with white paint; 5. binding the scions with the innovative adhesive tape “Buddy Tape” covering the buds; 6. binding the scions with the innovative adhesive tape “Buddy Tape” without covering the buds + painting the binding with white paint. The second experiment involved three options for limequat (Citrus Aurantiifolia x Citrus Japonica): 1. binding the scions with polyethylene tape without covering the buds; 2. binding the scions with polyethylene tape covering the buds; 3. binding the scions with the innovative adhesive tape “Buddy Tape” covering the buds.
The study results showed that the binding materials, the method of binding and the use of painting had a significant impact on the survival of scions, the budding time of the scions, the development of shoots and leaf surface on the scion component. In the experiment with sweet orange, the maximum survival rate (91.64%) was observed when binding the scions with the innovative adhesive tape “Buddy Tape” covering the buds, and the minimum rate (77.52%) was noted when binding the scions with polyethylene tape without covering the buds + painting the binding with white paint. The studies showed that the binding materials of the limequat scions had a significant effect on the budding time, the number of leaves on the shoot, the length of the shoot and the survival rate of the scion buds. The minimum budding time was found when binding the scions with the innovative adhesive tape “Buddy Tape” covering the buds, while the maximum budding time was noted when binding the scions with polyethylene tape covering the buds. The maximum survival rate was observed when binding the scions with the innovative adhesive tape “Buddy Tape” covering the buds, and the minimum one was when binding the scions with polyethylene tape covering the buds.
