黑美人松及复选优树特性分析

Characteristics analysis of Punusthunbergii × P. sylvestris var. sylvestriformis ‘baicheng-1' and superior trees

黑美人松是以黑松为母本、长白松为父本的人工杂交子代。测定发现其具有高生长量、高保存率的特点,树形、树皮颜色、针叶、芽、球果和花色等生物学特性表征较为复杂,分离严重,在抗逆性方面表现突出,尤其是复选出的15株优树在耐寒性、抗病虫危害方面表现更优。

Punusthunbergii × P. sylvestris var. sylvestriformis ‘baicheng-1' was artificial hybrid offspring whose female parent and male parent were Pinus thunbergii and Pinus syluestriformis. It had the characteristics high growth amount and high preservation rate. The biological characteristics such as tree shape,bark color,needles,buds,cones and flower color were more complicated,severely separated and outstanding in stress resistance,especially the 15 superior trees that were selected were better in cold resistance and pest resistance.
