Abstract:
The basal parts of the germinating strips of C.heterophylla×C.avellana were treated with IBA,ABT and GGR concentrations(500,750,1 000,1 250 mg?L-1).The effects of hormone and concentration on rooting of root-tiller seedlings were studied,and the dynamic changes of nutrient contents during rooting were discussed.The results showed that 1 000 mg?L-1 IBA treatment had the best rooting effect,with an average rooting rate of 87.92%.The number,length and thickness of primary lateral roots were significantly higher than those of other treatments and controls.During the rooting process,the soluble sugar and soluble protein content in the basal part of the sprouting strip treated with IBA showed a trend of ‘descending-ascending-descending’ and reached a peak at the adventitious root formation stage,while the total nitrogen content increased first and then decreased,and the content was lower than the control as a whole;the change of C/N ratio showed a trend of descending first and then rising.IBA treatment could promote the accumulation of soluble sugar,reduce the total nitrogen content,and increase the C/N ratio,which was conducive to the formation of root primordia and adventitious roots.
