摘要
杨树具有分布广、适应性强、生长迅速等特点,是造林绿化的重要树种。杨树多倍体诱导已成为近年来杨树育种的热点,培育出的良种具有生长快、抗性强和品质优的特点。该育种方法为林木育种提供了更为广阔的发展空间。对近年来杨树多倍体的诱导、鉴定等方面进行了概述,并对存在的问题提出了解决的建议,以期为杨树多倍体育种提供理论参考。
Poplars,important tree species for afforestation,had wide distribution,with strong adaptability,rapid growth.The poplar polyploid induction is becoming a hot spot of Poplar Breeding in recent years.By this methods,the improved varieties cultivated had the characteristics of fast growth,strong resistance and good quality.This method provides a broader space to development of forestry breeding.In this review,the induction,identification of poplar polyploid in recent years were summarized,then suggestions of solving the existing problems were put forward for providing theoretical reference for the poplar polyploid breeding.
