Abstract

An experiment on the taproot cutting of three-year-old seedlings of Carya cathayensis which were treated with different types of hormones of different mass fractions was carried out to accelerate their vegetative propagation and keep their excellent properties .The results indicated that the adventitious roots were developed from the callus , and the rooting rate , the number of new roots , the length of new roots and the diameter of new roots could be improved effectively with the treatment of 50 -100 mgkg-1NAA for 18 hours.However , 300 mgkg-1 auxin NAA could inhibit the formation of new roots .The cytokinin BA brought bad or no effects on the rooting of Carya cathayensis .The sources of root cutting and the measures for improving rooting rate were also studied .[ Ch , 6 tab . 9 ref .]
