Comparative Study on Growth Characteristics and Early Selection Efficiency of Hybrid Offspring of 'DD-109' and in Liaoning, China.

Poplar is an important tree species for timber supply and ecological protection in northern China. Cultivating and selecting high-quality varieties and germplasm resources suitable for cultivation are key factors in enhancing the quality and productivity of poplar plantations in the arid and semi-arid northern regions with shorter growing seasons. This study conducted a field cultivation experiment on 10 progeny clones from the direct cross (D × M) of imported 'DD-109' with and 7 progeny clones from the reciprocal cross (M × D) using one-year-old rooted cuttings planted at a 4 m × 8 m spacing.

Complete chloroplast genome sequence and phylogenetic analysis of Henry 1913 (Salicaceae Mirb.).

The classification and identification of species in has remained a formidable challenge due to widespread interspecies hybridization. The complete chloroplast genome of was obtained by Illumina high-throughput sequencing technology, with a typical quadripartite structure and 37.0% GC content.
