This invention discloses PtoNAC028 The gene is used to regulate the ratio of pectin monomers in poplar trees. The coding region of this gene has the nucleotide sequence shown in SEQ ID NO:1. This is achieved through overexpression or silencing of the gene in poplar trees. PtoNAC028 Genes capable of increasing or decreasing the proportion of lignin monomers in poplar provide key genes for the genetic improvement of poplar processing traits. This invention also discloses a method for cultivating poplars with a high lignin monomer ratio, through overexpression of [gene name missing] in poplar trees. PtoNAC028 The gene can significantly increase the proportion of lignin monomers in poplar trees, achieving targeted regulation of monomeric lignin metabolism, which helps to rapidly cultivate new poplar varieties with excellent wood properties and fast growth.

This invention discloses PCR primers and identification methods for distinguishing the sex of poplar trees from five major groups and the sex genotype of the white poplar group. This invention is based on the sex-determining gene in poplar trees. FERR Genes and FERR-R Specific primers were designed for each gene, and a PCR primer set for detecting the sex of poplar trees from five different groups was finally obtained through screening. PCR detection results of poplar materials with known sex using this primer set were completely consistent with the actual poplar sex phenotype, demonstrating that the PCR primer set provided by this invention can accurately identify the sex of poplar trees from the five different groups at the molecular level, making poplar sex identification more universal. Furthermore, the specific amplification provided by this invention... FERR The primer pairs for the gene can accurately identify the sex chromosome composition of poplar species. This invention has significant application prospects in the identification of male and female sexes in the five major poplar species, molecular breeding of poplars, and the control of female tree fluff.

A device and method for rapid calculation of forest stock volume, belonging to the field of forest calculation technology, uses a drone as a platform and integrates a lidar module, an optical camera module, a positioning and navigation module, a data storage module, a data transmission module, and a ground control module to achieve rapid collection, storage, transmission, and preliminary processing of forest parameters. It employs a drone-borne lidar and optical camera working in tandem, using 10 poplar trees as a standard measurement sample to achieve rapid, accurate, and efficient calculation of poplar stock volume. This significantly reduces the labor costs and time required for forest stock volume calculation, enabling calculation of a single forest plot to be completed within 1-2 days with an error controlled within 5%. It is applicable to scenarios such as forestry resource inventory, forest tenure valuation, carbon sequestration, and forestry management, providing accurate and efficient data support for relevant departments.
