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.

在四倍体的葡萄砧木上，降低了鼠的营养生长，新根的生长较小，而在不同土壤（andosol或黄色沙质土壤）的每个条件下，新根进化的土壤深度比原始二倍体砧木上的土壤深度较浅，并减少了土壤水。当将不同水平的氮应用于根系的每个半半时，砧木的生长大于将相同水平的氮水平施加到根系的每个半半。年轻的葡萄树被1毫米网状塑料网覆盖，并促进了塑料庇护所覆盖的年轻葡萄，因此人们认为促进生长是由风能保护引起的。
