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.

Stable and Efficient Agrobacterium-Mediated Genetic Transformation of Larch Using Embryogenic Callus.

or larch is an economically important coniferous tree species with rapid growth in the early stages, strong adaptability, and a short time to harvest. The genetic improvement of larch has garnered considerable attention in recent years for reclaiming timber forests. However, traditional breeding methods are largely ineffective for achieving rapid genetic improvement of .
