Abstract:
Taking one-year-old new hall navel orange seedling that grafted onto Fructus aurantii as material,the effect of different diameters of root stock on growth and development of citrus were studied,in order to provide high-quality nursery stock cultivation citrus with theoretical basis and provide reference for scientific management measures.The results showed that the larger root stock could promote growth of seedling height,length of mainroot and spring tip length,regulate born of secondary tip,third tip,fouth tip,growth of second to forth tip of seedling,leaf number,tip number and length of internode,and the total new born tip increment and leaf number of grafted seedling the same year,etc;the higher the root stock,the higher the seedling,and the higher the grafting seedling,the longer the length of mainroot,and the longer the spring wood;to other index,it showed increasing trend when graft diameter was 3.0～7.0 mm,and showed decreasing trend when graft diameter was 7.0～11.0 mm.Considering on breeding high-quality citrus seedling using root stock,it suggested the first to select the root stock diameter was 6.0~8.0 mm,then selected the diameter 5.0~6.0 mm and 8.0~9.0 mm root stock.
