These provinces include Inner Mongolia, Liaoning, Jilin, Heilongjiang, Zhejiang, Anhui, Fujian, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Shanxi, Gansu, and Xinjiang. Next, the elements that influence the efficiencies in the spatial error model (SEM) and spatial lag model (SLM) are evaluated. The results show that carbon sequestration efficiency differs for different output indices. The comprehensive efficiencies of the provinces in East China and South-central China are superior to those of the provinces in Northeast, North, Southeast and Northwest China. Both efficiencies are affected by adjacent provinces, though comprehensive efficiency is influenced the most. The level of technique and management is the most important element influencing the carbon sequestration efficiency and comprehensive efficiency. The influencing elements of carbon sequestration show that workers who have been laid off negatively impact the efficiency of governmental investment. Afforestation investment and wildlife and natural reserve investment have the greatest influence on carbon sequestration efficiency. An evaluation of comprehensive influential elements shows that the primary industry of forestry has a greater influence on efficiency than revenue from forest parks, although the government advocates for industrial transformation.

This method provides the necessary amount of viable sterile cultures for their subsequent micro-multiplication (clonal), sufficient for the further mass production of planting material.

Higher BAP concentration resulted in more regenerants from one explant with their height shortened. Woody Plant Medium (WPM) with different concentrations of 6-benzylaminopurine and indolyl-acetic acid (IAA) is more effective for working with triploid aspen. Effective reproduction at triploid aspen cultivation was shown at 0.5 mg/l concentration of BAP.

Initially, crude extracts of hexane, chloroform, and methanol from A. paniculata leaves were evaluated for their efficacy against Ae. aegypti and Cx. quinquefasciatus mosquitoes, with the methanol extract showing promising activity. Subsequently, a comprehensive methanol extraction of A. paniculata leaves was conducted, followed by fractionation via column chromatography using various eluents, including chloroform, ethyl acetate, methanol, and their combinations. This process yielded 80 fractions, which were consolidated into 10 fractions based on thin-layer chromatography (TLC) profiles. Each fraction was assessed for ovicidal, larvicidal, and pupicidal activity across concentrations of 2.5, 5.0, 7.5, and 10 ppm. Among these fractions, ‘F-4’ exhibited exceptional efficacy against the larvae, pupae, and eggs of both mosquito species. At a concentration of 10 ppm, ‘F-4’ achieved 100% larval mortality, with LC50 values of 7.2 ppm for Ae. aegypti and 5.0 ppm for Cx. quinquefasciatus. Additionally, ‘F-4’ demonstrated substantial pupicidal activity, with LC50 values of 7.6 ppm for Ae. aegypti and 5.7 ppm for Cx. quinquefasciatus. Furthermore, ‘F-4’ exhibited ovicidal activity, with efficacy ranging between 77% and 78%.
