【Abstract】 Chin.J.Appl.Ecol .,2002,13(12):1551～1554. Six new poplar clones were introduced in Qianshuangjing township of Changtu county,Liaoning Province as experiment materials,and their indeces in growth,cold resistance,disease infection,and insect infection were evaluated and compared to the locally grown Fuzha Ⅱ poplar. According to the comparison of the 4 indices,the study found that N 119 poplar showed all the scores obviously better than those of CK and other poplars,and was recommended for the area. The growth of Zhonglin 95 was higher,and its disease and pest infection was equal or near to the CK. So,the poplar Zhonglin 95 is also worthy to be recommended.更多还原
