黑杨派杨树新无性系物候期及生物学特性观测研究

Observation on the Phenophase and Biological Characteristics of New Black Poplar Clone

摘要:

摘要：对黑杨派杨树I-63杨和I-69杨人工杂交获得的优良单株LH04-13，以I-69杨、I-63杨、南林895、中石7号杨等为对照营建试验林，观测研究各无性系萌芽展叶、生长、封顶落叶、开花结实等物侯期及生物学特性适应性、抗逆性等，以期为杨树无性系的选育及造林推广提供理论依据。

Abstract:

Abstracts:LH04-13 was a superior individual acquired through artificial hybridization between black poplar clone I-63 and I-69.In order to observe the phenophase and biological characteristics of LH04-13 , experimental forest was established with black poplar clone I-69,I-63,Nanlin895,Zhongshi7 etc as control.The period of bud exhibition leaf, growth,capping,defoliation, flowering and seeding of all poplar clones were monitored and compared.With the purpose of providing theoretical basis for poplar clones breeding and planting,the adaptability and adversity resistance of all clones were also analyzed.
