| Research Abstract |
On the tetraploid grape rootstocks reduced the vegetative growth of scion cultivars, growth of new roots was smaller and soil depth of new root evolution was shallower than those on the original diploid rootstocks in each conditions of different soils(andosol or yellow sandy soil) and reduced soil water. When different level of nitrogen was applied to each halves of root system, growths of rootstocks were larger than those applied the same level of nitrogen to each halves of root system. Young grapevines covered with 1-mm mesh plastic net was promoted the growth as well as those covered with plastic shelter, thus the growth promotion was thought to be induced by wind protection.
