Abstract:
Taking Baleng Crab (BC) vigorous seedling rootstock，M9 and SH40 dwarfing rootstocks，or M9 and SH40 interstems with Baleng Crab as rootstocks，and ‘Red Fuji’(RF) apple cultivars were grafted onto them，using minirhizotron system，the relationship between root and top growth were analyzed.The results showed that root length density，surface area density，volume density and density of root tip number acted as RF/BC>RF/SH40/BC>RF/M9/BC>RF/M9>RF/SH40 in annual mean.Compared with RF/BC (vigorous)，inserting a dwarfing interstem between scion and Baleng Crab seedling rootstock，the root length density(RLD) reduced，but it was superior to that of dwarfing rootstock.Plants with M9 or SH40 interstock showed lower vegetative growth.Correlation analysis showed that total shoot length (TSL)，diameter of trunk (DT)，short shoots number (SN) and long shoots number (LN) could be used as the important indicators to judge the root characteristics，and in which LN and TSL were the major indicators to judge multinomial root characteristics.
