A Study on the Graft-cutting of Rose by the Film Packing Method

Abstract

This is a study on the effects of plastics used for graftings. This report deals with a simple examination of the various aspects of grafting unions of rootless stocks, and with its applications like grafting-cuttings of rosaceous trees, as a new agricultural experiment. This is a discovery second to the report on the leaf-removal and longtime storage of grafting scions by S. MIKI. The previous report was made in 1) and explained the longtime storage of scions and its perfect results. Through soft plastic film packing the storage method has provod successful.
1. According to this simple inspection method of grafting unions, examination may be con-ducted throughout the year. Naturally wintertime storage is feasible then, and grafting union is sure if the grafting are preserved till warm springtime. Thus winter grafting may become a good side-job for farmers in their wintry slack season.
2. The sole difficulty in this storage method is the growth of mold and eventual decay of the materials just as in case of scion storage. Lower temperature invites less mold.
3. As for grafting-cutting to which this method may be applied most effectively, so for as the stocks are usable for cuttings, good results will be gained on the nine fruit trees and many other trees.
4. The combination of scion and stock in grafting-cuttings must be normal/revrse, which has been verified as the best combination in many experiments. This can be a quicker way of conducting examination only.
5. This method can be adopted indoor working of rooted stocks as well as of rootlese stocks.
