Research progress on rootstock of kiwifruit

The commercial cultivation history of kiwifruit is not long and research on the rootstock of kiwifruit is little all over the world. Special rootstocks were lack in kiwifruit production,it is usually adopted by grafting with Actinidia Chinensis or A. deliciosa,the same species as the scion. Previous studies have shown that application of A. hemleyana,A. erianths,and A. valvata as rootstock promotes flower bud formation of‘Hayward',‘Hongyang‘ and other varieties of kiwifruit,improves drought tolerance,water logging endurance,high pH tolerance and so on. In this paper,the profiles of rootstock application of kiwifruit,the affinity of root stock and scion,the influence of rootstock on scion growth characteristics,the rootstock resistance and the other research progress were reviewed,that provide a basis to evaluate and identify rootstock resistance,to screen and cultivate good rootstock and pair of scion with rootstock,to enhance kiwifruit resistance,to increase its ecological adaptability,and to promote the healthy development of kiwifruit industry.
