In response to global warming issues, the entire world community seeks to decarbonize its energy and economy. One of the ways to reduce concentrated greenhouse gases in the atmosphere is to enlarge forest areas and encourage forest regeneration after fires. The given paper describes sterilization methods of primary explants. Studies have shown that 0.1% diacid solution supplemented with Tween 20 is the most effective at producing aseptic viable cultures of triploid aspen (Populus tremula L.) in vitro. 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. Murashige & Skoog (MS) medium supplemented with 6-benzylaminopurine (BAP) had a more intensive formation of adventive buds compared to the medium with kinetin. 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. The research results can be successfully used in vitro culture introducing of triploid aspen, experiments on micro-reproduction of other tree crops to get high-quality planting material.
为了应对全球变暖问题,整个国际社会都在寻求使其能源和经济脱碳。减少大气中集中的温室气体的方法之一是扩大森林面积,鼓励森林在火灾后再生。本文介绍了初生外植体的灭菌方法。研究表明,0.1%的二酸溶液中添加Tween 20对三倍体白杨(Populus tremula L.)无菌活菌的体外培养效果最好。该方法为其后续的微增殖(克隆)提供了必要数量的有活力的无菌培养物,足以进一步大量生产种植材料。Murashige & Skoog (MS)培养基中添加6-苄基氨基嘌呤(BAP)比添加动蛋白的培养基更能形成不定芽。BAP浓度越高,一个外植体再生体数量越多,再生体高度缩短。不同浓度6-苄基氨基嘌呤和吲哚乙酸(IAA)的木本植物培养基(WPM)对三倍体杨树的处理效果更好。BAP浓度为0.5 mg/l时,三倍体杨树繁殖效果良好。研究结果可成功应用于三倍体杨树离体培养引种、其他林木作物微繁殖试验,获得优质种植材料。

In the quest for environmentally friendly alternatives to combat the challenges of resistance development and environmental toxicity associated with synthetic insecticides in mosquito control, the aim of this study is to explore the potential of fractions derived from Andrographis paniculata as environmentally friendly alternatives for controlling Aedes aegypti and Culex quinquefasciatus mosquitoes, with a focus on assessing their larvicidal, pupicidal, and ovicidal activities. 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%. These results highlight ‘F-4’ from A. paniculata shows promise as an eco-friendly biocontrol agent against Ae. aegypti and Cx. quinquefasciatus mosquitoes, warranting further investigation for sustainable mosquito control.

The present work is the first attempt to monitor the spectroscopic characteristics of polluted plants in Abu Zabaal area. Spectral signatures for plants in the study area have been measured by ASD spectroradiometer to assess the status of plants species. Various hyperspectral indices of Plant and soil were calculated to evaluate the samples representing the soil and studied plant species. The analysis showed that chlorophyll a and b content decreased in all plant species under pollution in comparison with control ones. There is a change in chlorophyll fluorescence under pollution conditions. The experimental results were matching with the hyperspectral indices, especially the red edge vegetation indices (RE, MRENDVI, and RE-NDVI). Based on linear regression analyses, an innovative model for assessing HCO3% was generated using SAVI retrieved from hyperspectral data, giving a promising accuracy (90%).

本工作是首次尝试监测阿布扎巴尔地区受污染植物的光谱特征。通过ASD光谱辐射计测量了研究区域内植物的光谱特征,以评估植物物种的状况。计算了植物和土壤的各种高光谱指数,以评估代表土壤和研究植物物种的样品。分析表明,与对照植物相比,所有受污染植物的叶绿素a和b含量都有所下降。在污染条件下,叶绿素荧光发生变化。实验结果与高光谱指数,特别是红边植被指数(RE、MRENDVI和RE-NDVI)相匹配。基于线性回归分析,使用从高光谱数据中检索的SAVI生成了一个用于评估HCO3%的创新模型,给出了有希望的准确率(90%)。

Steady cultivar selection for the production of essential oil of palmarosa (Cymbopogon martinii [Roxb.] Wats. var. motia Burk.) in the semi-arid tropical Deccan plateau region of southern India 马提兰精油生产的稳定品种选择[j]。寺庙。产于印度南部半干旱的热带德干高原地区

The development of the rose-scented palmarosa crop stable varieties is primarily driven by the essential oil it contains, which is highly valued in the fragrance and cosmetics industries because of its high geraniol and geranyl acetate content. The objective of this investigation was to improve the stable yield and quality of the essential oil. Traditional breeding relies heavily on the harvesting phase to maintain consistency in the essential oil content. Findings from the AMMI and GGE analyses showed that various kinds exhibit both general and niche environmental adaptability. The mean essential oil yields, as well as geraniol and geranyl acetate, were significantly influenced by both genetic variation and environmental variables. The stability of the traits is also influenced by the correlations between different attributes across the four stages of the eight seasons/environments. Pr2 at full blooming stages 1 and 2 and Pr4 at full blooming stage 1 had stability for the maximum oil yield, geraniol, and geranyl acetate, based on the overall average of the eight seasons/environments in four stages of the crop. Because they have higher G × E, which makes them more sensitive to environmental changes, the AMMI model identified Pr2 at full flowering stages 1 and 2 and Pr4 at full flowering stage 1 as being more stable and better suited to their environments. Of the four varieties studied, Pr2 full flowering stages 1 and 2 and Pr4 full flowering stage 1 were identified as higher essential oil yielders and stable, and they also possessed other desirable characteristics like high herb’ plant height, branches/plant, geraniol content, and geranyl acetate content. Therefore, commercial-scale production should take advantage of these stable cultivars.
玫瑰香棕榈草作物稳定品种的发展主要是由其所含的精油驱动的,这种精油因其高香叶醇和香叶乙酸酯含量而在香水和化妆品行业受到高度重视。本研究的目的是为了提高挥发油的稳定收率和质量。传统育种在很大程度上依赖于收获阶段,以保持精油含量的一致性。AMMI和GGE分析结果表明,不同种类的植物均表现出一般和生态位环境适应性。平均精油产量、香叶醇和香叶乙酸酯均受遗传变异和环境变量的显著影响。性状的稳定性还受到8个季节/环境4个阶段中不同属性间相关性的影响。从作物4个生育期8个季节/环境的总体平均值来看,1、2盛花期Pr2和1盛花期Pr4在最大油料产量、香叶醇和香叶乙酸酯方面具有稳定性。由于它们具有更高的gxe,对环境变化更敏感,因此AMMI模型认为Pr2和Pr4在盛花期1和2和Pr4在盛花期1更稳定,更适应环境。在研究的4个品种中,Pr2盛花期1、2期和Pr4盛花期1期被认为是精油产量较高且稳定的品种,它们还具有较高的草本株高、枝/株高、香叶醇含量和香叶乙酸含量等理想特性。因此,商业规模生产应充分利用这些稳定的品种。

The objective of this investigation was to improve the stable yield and quality of the essential oil. Traditional breeding relies heavily on the harvesting phase to maintain consistency in the essential oil content. Findings from the AMMI and GGE analyses showed that various kinds exhibit both general and niche environmental adaptability. The mean essential oil yields, as well as geraniol and geranyl acetate, were significantly influenced by both genetic variation and environmental variables. The stability of the traits is also influenced by the correlations between different attributes across the four stages of the eight seasons/environments. Pr2 at full blooming stages 1 and 2 and Pr4 at full blooming stage 1 had stability for the maximum oil yield, geraniol, and geranyl acetate, based on the overall average of the eight seasons/environments in four stages of the crop. Because they have higher G × E, which makes them more sensitive to environmental changes, the AMMI model identified Pr2 at full flowering stages 1 and 2 and Pr4 at full flowering stage 1 as being more stable and better suited to their environments. Of the four varieties studied, Pr2 full flowering stages 1 and 2 and Pr4 full flowering stage 1 were identified as higher essential oil yielders and stable, and they also possessed other desirable characteristics like high herb’ plant height, branches/plant, geraniol content, and geranyl acetate content.
