Evaluation of total protein,peroxidase,and nutrients measured by pXRF for the determination of tissue rejuvenation/reinvigoration of Eucalyptus microcorys

Ontogenetic aging of tissues and the gradual decrease of adventitious rooting are known challenges for the clonal propagation of woody species,hampering clonal forestry programs.This study examined possible signatures of tissue rejuvenation/reinvigoration in different propagated materials of Eucalyptus microcorys by analyzing the total protein profile,peroxidase activity,macro-and micronutrient contents,and adventitious rooting of mini cuttings.The analyses were performed on E.microcorys shoots which were successfully obtained by seminal and grafting propagation,micropropagation with epicormic shoots,and indirect organogenesis.Among four mature trees used in the propagation,tissues from the one with the best propagation results were investigated for signs of tissue rejuvenation and/or reinvigoration.Five individuals from each technique were randomly selected and transferred to a semi-hydroponic"channel"system.After four weeks in the seedbed,the total protein,peroxidase activity,nutrient content and rooting of the mini cuttings were evaluated.SDS-PAGE enabled the differentiation of leaf samples obtained by grafting from the other propagation techniques,as revealed by two distinct bands.Materials obtained by micropropagation with epicormic shoots showed the highest peroxidase activity,while those obtained by seminal propagation and from the selected mature tree showed the lowest peroxidase activity.A portable X-ray fluorescence spectroscope(pXRF)identified adequate nutrient content in most of the nutrients tested in materials obtained by seminal and grafting propagation,and by indirect organogenesis.The analysis of adventitious rooting showed that the highest rooting percentage was observed in mini cuttings from seminal propagation(75%)followed by indirect organogenesis(35%).Based on principal component analysis,it was concluded that rooting of mini cuttings from both seminal propagation and indirect organogenesis was associated with phosphorous,sulphur,and potassium contents,which suggests a higher level of tissue rejuvenation/reinvigoration in these propagated plants.Further studies are recommended to search for other methods that present similarities with the responses to adventitious rooting in forest species and thus optimize the rescue and propagation of plants with distinct ontogenetic stages.

Relationship between age, size, fecundity and climatic factors in Panax wangianus an endangered medicinal plant in the sacred grove forest of North-East India

Panax wangianus （Syn. Panax pseudoginseng） S. C. Sun （Araliaceae） is a critically endangered, medicinal plant of North-East India. The objective of this study was to determine how plant size affects flowering phenology and to evaluate the effect of climatic factors on flowering, fruiting and seed production. Data on vegetative and repro- ductive characters were monitored from 2016 individuals of Panax wangianus population in Law Lyngdoh, Smit sacred grove in Nongkrem, Shillong, India. Leaflet area was measured by a planimeter. Size variables of both vegetative and reproductive traits in different age classes were measured. Climatic factors were recorded from 2007 to 2009. Age was recorded by counting the number of bud scale scars on the rhizome. Light intensity and relative humidity were measured using a photometer, LiCor Model LI-189 and thermohygrometer respectively. Different climatic variables are correlated with vegetative and reproductive phenological events. Statistical analysis revealed that a strong positive correlation was observed between the age versus vegetative and reproductive characters, except 1%–2% plants showed neoteny. Morphological variations were observed in natural conditions on the basis of the number of prong and carpellate conditions. Phenological status revealed that most of the individuals of the age class 35–50 years and above 50 years contributed the most to flowering, fruiting and seed production. Age class was significant to predict the size of the plant and its reproductive capacity. Climatic factors such as temperature, precipitation and relative humidity show synergistic effect on both the vegetative and reproductive phases in Panax wangianus in the undisturbed Nongkrem sacred grove. The color of flowers of P. wangianus also varied depending upon the sunlight intensity. Therefore, in the view of conservationand management, the age class of 35–50 years and above 50 years is the most important for population sustainability.

Talcott Parsons＇ AGIL Schema-based System Identification of Administrative Problems of North-East Vocational Education in Thailand

Talcott Parsons was a great well-known sociologist whose approach was based on system theory. He identified social system into subsystems which were A （Adaptation functions）, G （Goal gratification functions）, I （Integration functions）, and L （Latent pattern maintenance functions）. His approach was based on the concern for the stability or maintenance of social system. The aim of this research is experimentally to identify the social system of north-east vocational education＇s macro administrative problems in Thailand by utilizing AGIL schema. The writer has adopted the symbiosis or maintenance of socials system stance by utilizing this approach. The results of the research were, firstly, the major macro vocational education eight problems （sentences） and 27 sub-problems （sentences） and secondly, the 15 diagrams of above-mentioned problems and sub-problems after utilizing AGIL concepts （In this paper, the writer illustrated seven of them）. The study had been done using both secondary and primary data. The secondary data were collected from the written documents and from the internet concerning the vocational schools. In depth interview data were collected. Some respondents have been interviewed more than once. The total of 69 times in depth interview were collected. The researcher had utilized Japanese Kawakita Jiro Method of processing scattering paper clips from these primary and secondary data. In conclusion, the detail of main findings, system of sentences of the macro problems, some derived diagrams examples （After AGIL schema applying） and also implication from the main findings have been illustrated.

Mineralogy of Meteorites from the North-Eastern India: A Brief Review

We present a brief overview of meteorites from the north-eastern India, with a focus on falls, finds, and research developments. To date, out of a total 150 numbers of meteorites fall/find in India (in Meteoritical Bulletin Database), only six meteorites from north-eastern region have received official international recognition from the Nomenclature Committee of the Meteoritical Society. Among these six meteorites, 2 finds and 4 falls, including one ureilite, two H chondrites and three L chondrites. The first meteorite from north-eastern India (Assam L5, Find) was documented in 1846. After a lack of 153 years, the first fall (Sabrum LL6 chondrite) was documented in 1999. The most recent fall is Kamargaon (L6) chondrite in 2015. Intensively researched meteorites of this region are Goalpara and Dergaon. The reported most massive meteorite of north-eastern India is Mahadevpur (H4/5) chondrite, 70.5 kg of total known weight, and the rest are <13 kg of total known weight. The researches on these meteorites from north-east India can be applied to the newly recovered meteorites to understand the astrophysical enigma.

人才强国战略的政策扩散与发展——基于2002—2021年政策文献的量化研究

人才强国战略是我国的核心战略之一,而人才政策则是该战略落地的重要载体。从政策扩散视角出发,基于政策文献计量分析方法对我国2002—2021年中央和地方政府颁布的有关“人才强国战略”的2163件政策文本进行分析,构建政策参照网络,结合关键词时序分析方法对人才强国相关政策的扩散强度、广度、速度和方向四个特征进行量化研究。研究发现我国政策颁布机构参照网络呈现出明显的三级结构。规划类政策具有较高的政策扩散强度和广度,且其扩散强度增长可以跨越政策文件的全部有效期,与意见/决定类文件形成对比,后者扩散强度增长仅能持续4—7年。通过关键词时序图谱对人才强国政策扩散中自上而下、自下而上、同级扩散、跟随扩散模式进行了重点分析。针对我国人才强国政策扩散过程进行研究,探索人才强国政策扩散与发展的特点,并为相关政策理论体系及后续实践提供参考意见。

补肾平喘膏方对支气管哮喘大鼠肺组织糖皮质激素受体的影响

目的:观察支气管哮喘大鼠肺组织中糖皮质激素受体(glucocorticoid receptor,GR)的变化情况以及补肾平喘膏方对其的影响,以探讨补肾平喘膏方防治支气管哮喘的作用机制。方法:60只SD大鼠随机分为正常对照组、模型组、地塞米松组、膏方预防组、膏方治疗组和膏方防治(预防加治疗)组,每组10只。除正常对照组外,各组大鼠以卵白蛋白致敏并诱发哮喘模型。采用地塞米松或膏方治疗后,HE染色法检测大鼠肺组织病理学改变,免疫组织化学法检测肺组织中GR的表达情况。结果:模型组肺组织GR表达低于正常对照组(P<0.05),膏方预防组、治疗组、防治组肺组织GR的表达较模型组明显上调(P<0.05),与正常对照组比较,差异无统计学意义(P>0.05)。其中膏方预防组GR的表达显著上升(P<0.01),膏方各组与地塞米松组相比亦明显上升(P<0.01)。结论:补肾平喘膏方可能通过上调哮喘大鼠肺组织中GR的水平治疗哮喘。

古槐树的保护与复壮研究

通过对古槐树的生长环境和生长状况的调查,并对植株叶片营养元素含量和生长地周边的土壤中营养元素含量进行定量分析,结果表明:土壤中的营养极度缺乏,根系得到的营养物质极为有限,这样,使根系无法生长,造成树体的伤害。在给古槐施用肥料中有必要增加N、P、Ca、Mg、Zn等营养元素,使古槐能更旺盛地生长。还对古槐树的保护和复壮提出措施,以期为延缓古树的衰老提供理论依据和切实可行的方法。
