Clone GT1 is one of the low metabolism clones and is recommended for smallholder and large plantations. These clones are responsive to stimulants and reach production peak at the mid-economic cycle period. Its production can reach 2200-3000 kg-1ha-1year-1 and is relatively more resistant to high exploitation pressures if the agroecosystem conditions are suitable. This study aimed to determine the effect of the combined application of liquid stimulant concentration and tapping interval on the physiology and productivity of latex in rubber clone GT1. This research was conducted at Naga Rejo Village, Galang District, Regency of Deli Serdang, Province of Sumatera Utara, located at an altitude of 49 masl with Ultisol soil type. The research design is factorial randomized completed block design (RCBD) consisting of 9 levels, namely S2d4 without a stimulant, S2d4 ET 3.5%, S2d4 ET 4.5%, S2d5 without a stimulant, S2d5 ET 3.5%, S2d5 ET 4.5%, S2d6 without a stimulant, S2d6 ET 3.5%, S2d6 ET 4.5 % with three replicas of each treatment. The results showed that the tapping system on clone GT1 obtained the highest annual production with tapping system S2d4 ET 4.5% (DS3) of 214.51 g/t/y. The lowest production is obtained in January-March when the leaves fall. High sucrose levels in the non-stimulant treatment (8.54 -12.98 mM) indicated that at least sucrose was converted into latex. The pH of latex is directly proportional to the stimulant, so an increase in the concentration of the stimulant raises the pH and metabolism of latex formation.
克隆GT1是低代谢克隆之一，推荐用于小型和大型种植园。这些克隆对兴奋剂有反应，并在经济周期中期达到产量峰值。如果农业生态系统条件合适，其产量可达到2200-3000公斤-1公顷-1年-1，相对而言更能抵抗高开发压力。本研究旨在确定液体刺激剂浓度和振打间隔对GT1橡胶无性系胶乳生理和产量的影响。本研究在北苏门答腊省德利塞尔当县加朗区Naga Rejo村进行，该村海拔49米，土壤类型为Ultisol。研究设计为析因随机完全区组设计（RCBD），由9个水平组成，即不含刺激物的S2d4、S2d4 ET 3.5%、S2d4ET 4.5%、不含刺激剂的S2d5、S2d5ET 3.5%、不含兴奋剂的S2d6、S2d6ET 3.5%和S2d6ET4.5%，每个治疗有三个复制品。结果表明，克隆GT1上的出穗系统年产量最高，出穗系统S2d4 ET 4.5%（DS3）为214.51g/t/y。产量最低的是在1-3月落叶的时候。非刺激处理中的高蔗糖水平（8.54-12.98mM）表明至少蔗糖转化为胶乳。乳胶的pH值与兴奋剂成正比，因此兴奋剂浓度的增加会提高乳胶形成的pH值和新陈代谢。

Chickpea (Cicer arietinum L.) is a crucial source of dietary protein and accounts for 18% of global legume production. However, the crop faces a variety of biotic and abiotic constraints, with fusarium wilt being the most common soil-borne disease. This disease poses a significant threat to chickpeas, leading to yield losses of up to 80% worldwide. Fusarium wilt pathogens exhibit host specificity and characteristic symptoms in mature plants include brown to black discoloration of the xylem vessels, wilting, and leaf burning caused by phytotoxins produced by the pathogen. To combat this fungal disease, several cultural, biological, and chemical methods have been extensively employed. While chemical control methods have proven to be highly effective and widely adopted by growers, they come with several adverse consequences for humans, the environment, soil, and water. Moreover, improper and excessive use of fungicides can lead to the development of resistance in plant pathogens. Thus, there is a pressing need for an environmentally friendly approach that promotes plant resistance. One such approach is induced resistance, which involves enabling plants to build their own resistance mechanisms. Induced resistance can take different forms, such as systemic acquired resistance based on the salicylic acid pathway, and induced systemic resistance based on the jasmonic acid pathway.

The study examines the economics of different paddy straw management methods in rice-wheat systems in Gurdaspur, Punjab during the Rabi seasons (2019-20 and 2020-21). The experiment was carried out with 2 wheat varieties, HD 3086 (V1) and PBW 550 (V2), using varied treatment combinations of crop residue management approaches, tillage and seed drilling methods. Based on the pooled data, the PAU (Punjab Agricultural University) cutter cum spreader + incorporation with Mould Board plough + Use of Seed drill (M4) treatment produced the highest plant height (95.87 cm). Treatment PAU cutter cum spreader + PAU happy seeder with press wheel (M2) (437.71) had the highest density of tillers per square meter, significantly outperforming other treatments. A significant interaction was observed between paddy residue management methods and varieties in terms of the number of tillers. Maximum spike length (12.81 cm) was obtained with Stubble Shaver + Burning + Zero Tillage Drill (M1), whereas maximum number of spikelets per spike (18.33) was noted in method (M2). The treatment method (M2) turned out to be the most efficient in terms of yield (44.02 q/ha) and benefit cost ratio (1.72).

Research on the natural resources found in medicinal plants and endophytes makes important contributions to a wide variety of fields, including drug development, agribusiness, biotechnology, and sustainable development. Endophytes are a group of microorganisms that can be discovered in the rhizosphere of plants being used in medical treatment. These microorganisms have the capability of producing a wide range of primary and secondary metabolites by utilizing a variety of distinct biosynthetic pathways. Several different technologies, such as genetic modification and artificial intelligence (AI), play a significant role in the acceleration of endophytic research. These methods aid in the discovery and synthesis of novel compounds with medicinal promise, the predictive analysis of bioactive compounds, the identification and classification of endophytes, and the optimization of potential bioactive compounds. In light of this, the current review focuses on providing a concise comprehension of the influence of bioactive compounds secreted by specific endophytes on medicinal plants through the application of significant technologies in the field of endophytic research.

The current study aims to assess the impact of different genotypes, environmental conditions, and their interactions (G×E) on lentil yield and nutritive traits in various agro-ecological locations across Morocco. To achieve this, two analysis methods, Analysis of Main Additive Effects and Multiplicative Interaction (AMMI), and Genotype and Genotype by Environment (GGE) were used. The study involved evaluating sixty-four lentil genotypes in six diverse environments during the 2017–2018 and 2019–2020 seasons. Results from the analysis of variance revealed that environmental variation significantly influenced grain yield (75.7%), zinc (48.4%), and magnesium (73.3%). In contrast, genotype by environment interaction (G×E) played a more substantial role in determining protein (45.7%), iron (53.2%), and manganese (49.6%) content. The first two components explained 69.2%, 78.3%, 90.5%, 79.3%, 71.4%, and 74.3% of the variation in grain yield, protein content, iron, zinc, manganese, and magnesium, respectively. The GGE biplot analysis identified specific environments (E3 and E5) as representative and discriminative for yield, zinc, and manganese. Similarly, E3 and E4 were discriminative for iron and protein and magnesium, respectively. Seventeen lentil genotypes exhibited high performance, combining yield and nutritional quality. Notably, genotypes LN34 and VR28 performed well in the Marchouch 2019-2020 environment, while genotype LN54 excelled in the Douyet and Sidi el Aydi environments during 2019-2020. Furthermore, three advanced lines (LN34, LN58 and LN64) expressed stability in yield and most nutrient traits, outperforming released lentil varieties. These promising lines hold potential for developing novel, resilient lentil varieties with both high yield and nutritive quality.
目前的研究旨在评估不同基因型、环境条件及其相互作用(G×E)对摩洛哥各地不同农业生态地点扁豆产量和营养性状的影响。为此，采用了主加性效应和倍增性相互作用分析(AMMI)和环境基因型和基因型分析(GGE)两种分析方法。该研究涉及在2017-2018年和2019-2020年期间评估六种不同环境下的64种小扁豆基因型。方差分析结果显示，环境变化对籽粒产量(75.7%)、锌(48.4%)和镁(73.3%)有显著影响。相比之下，环境互作基因型(G×E)对蛋白质(45.7%)、铁(53.2%)和锰(49.6%)含量的影响更大。前两个组分对籽粒产量、蛋白质含量、铁、锌、锰、镁的贡献率分别为69.2%、78.3%、90.5%、79.3%、71.4%和74.3%。GGE双图分析确定了特定环境(E3和E5)对产量、锌和锰具有代表性和歧视性。同样，E3和E4分别对铁、蛋白质和镁具有鉴别性。17个小扁豆基因型表现出较高的生产性能、综合产量和营养品质。值得注意的是，基因型LN34和VR28在2019-2020年Marchouch环境中表现良好，而基因型LN54在2019-2020年Douyet和Sidi el Aydi环境中表现优异。此外，3个先进品系LN34、LN58和LN64在产量和大部分营养性状上表现稳定，优于其他扁豆品种。这些有希望的品系有潜力开发出具有高产和高营养品质的抗逆性扁豆新品种。

One of the primary abiotic factors limiting rice production is zinc (Zn) deficiency. Effective management of Zn in rice soils is crucial, as rice is a staple crop for many nations. To address this issue, a pot trial was conducted at the net house of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh,from December 2019 to May 2020. The trail aimed to assess the impact of zinc on yield performance and grain zinc content of rice. The experiment employed a completely randomized design (CRD) with three replications, involving the applications of six different rates of Zn to three distinct varieties of boro rice. The result revealed that BRRI dhan28 exhibited superior yield and yield-related traits when treated with 12 kg Zn ha-1. Meanwhile, the application of 10 kg Zn ha-1 resulted in the highest Zn content in the grain of BRRI dhan74, considering the quantity of Zn accumulated by the grain. Based on the findings of the study, it can be concluded that applying 12 kg of Zn ha-1 is likely the optimal Zn management strategy to achieve outstanding performance in the rice cultivar BRRI dhan28. Furthermore, applying 10 kg of Zn ha-1 may enhance the Zn content of the grain in BRRI dhan74.
锌缺乏是制约水稻生产的主要非生物因素之一。水稻土壤中锌的有效管理至关重要，因为水稻是许多国家的主要作物。为了解决这一问题，于2019年12月至2020年5月在孟加拉国农业大学Mymensingh农学系的网房进行了盆栽试验。本试验旨在评价锌对水稻产量和籽粒锌含量的影响。本试验采用完全随机设计(CRD)， 3个重复，对3个不同品种水稻施用6种不同锌浓度。结果表明，在12 kg Zn ha-1处理下，BRRI dhan28表现出较好的产量及产量相关性状。同时，考虑到籽粒锌积累量，施用10 kg Zn ha-1的BRRI dhan74籽粒锌含量最高。综上所述，在水稻品种BRRI dhan28中，施用12 kg Zn ha-1可能是获得优异表现的最佳Zn管理策略。此外，施用10 kg Zn ha-1可以提高BRRI dhan74籽粒Zn含量。

Garcinia species (G. indica, G. cambogia, G. kola and G. mangostana) represent some of the most sought-after herbs globally due to their impressive medicinal qualities, hence the ever-growing interest of researchers into these plants. In this study, an extensive bibliometric analysis of the available research outputs on the widely-known Garcinia species was conducted to appraise the progress made and also highlight the future focus of research on the plants. The published articles (original and conference articles) on the selected species from 1991 to 2021 were retrieved from Scopus® database, scrutinized and further analyzed using the VOS viewer software. Over 2000 research outputs were published posting an annual publication rate of 75 articles, which have altogether garnered almost 37000 citations within the period under review. Of the 85 country affiliations on the publications, 5, which include India, Thailand, Nigeria, Indonesia, and the United States have cumulatively contributed two-thirds of the total outputs. The institutions; the University of Ibadan (97), Prince Songkla University (52) and Mahidol University (50) have the most publications revealing their research focus on herbs. However, in terms of individual influence, Prof E.O. Farombi, of the University of Ibadan, led the pack with an impressive 42 publications (1585 citations) on Garcinia kola followed by Prof Y.W. Chin of the Seoul National University, South Korea with 23 publications (452 citations) on Garcinia mangostana. The versatility in the health applications of these species especially as sources for new therapeutics, nutraceuticals or functional food ingredients, has been the main driver of the research within the past three decades. Recent research undertakings have demonstrated the potential industrial uses of herbs in the clothing and petroleum industries and these may dominate the research emphases in the immediate future.

Plant growth regulators control various physiological processes in plants, including growth and development. Among these regulators, brassinosteroids (BRs) have emerged as important phytohormones with diverse roles in crop development and metabolism. They influence processes like cell division, elongation, reproduction, flowering, vascular differentiation, fruit ripening, root formation, and responses to both biotic and abiotic stressors. Additionally, BRs enhance tolerance and resilience to these stressors. Their impact on fruit trees' defense mechanisms holds significant potential for the fruit industry. This review focuses on the wide-ranging physiological and economic importance of BRs in modern fruit production, highlighting their applications and implications through conceptual research and development efforts.

The Butuanon is one of the ethnolinguistic groups in the Philippines. The artefacts discovered by the locals and treasure hunters in Butuan City demonstrated that Butuanon is rich in history, culture, and tradition. However, they need more records of their traditional healthcare knowledge and practices. Therefore, this study documented Butuanon’s traditional knowledge and practices for managing illnesses and diseases using medicinal plants. Thirteen key informants were identified and interviewed through the snowball technique after obtaining their consent. The informants used a total of 132 plant species, which correspond to 116 genera and 57 families. The highest-represented family was Fabaceae, followed by Lamiaceae, with 11 and nine species, respectively. Many of the documented plants were herbaceous (37%), followed by trees (29%), shrubs (23%), and vines (11%). The informants commonly used leaves (43%), followed by roots (15%), bark (12%), fruit (7%), and flowers (5%). These plant species treated 93 different illnesses and diseases, of which fever had the highest number of plants used (18%), followed by diabetes (17%), urinary tract infection (16%), cough (15%), hypertension (14%), diarrhoea (11%), cuts and wounds (11%), relapse (8%), kidney dysfunction and disease (6%), and arthritis (6%). In conclusion, this study sheds light on the Butuanon community’s ongoing utilization of medicinal plants for their healthcare needs. This underscores the need to preserve their traditional alternative medicine and conserve Philippine medicinal plants.
