. Abiu is a new, excellent, and rare fruit. The genetic diversity of 20 Abiu germplasm resources was determined using SCoT molecular marker technology. A total of 361 bands were amplified using 24 selected primers, including 309 polymorphic bands, with an average polymorphism ratio (PPB) of 85.60%. The number of alleles ( Na ) in the population was 1.9501, number of effective alleles ( Ne ) was 1.4659, gene diversity index ( H ) was 0.2806, and Shannon diversity index ( I ) was 0.4314, indicating high genetic diversity among the materials. The results of cluster analysis showed that the inter-specific genetic coefficient of 20 varieties of Abiu was between 0.53-0.76, and the results of principal component analysis were consistent with those of cluster analysis. The analysis of the population structure revealed that the 20 Abiu samples could be categorized into seven distinct groups. Of all the tested materials, 14 samples had diverse genetic backgrounds and complex genetic compositions, accounting for 70% of the tested materials, suggesting that the population genetics of the 20 samples had a rich genetic basis and complex and diverse sources. SCoT, which is an effective molecular marker, can be used to analyze the genetic diversity of the germplasm resources of Abiu. This study will be useful for the identification, collection, classification, protection, and evaluation of Abiu germplasm resources.

. The problem of continuous cropping obstacle has seriously restricted the development of the ginseng industry. In view of the little research on the mechanism of ginseng crop disorder, this study was conducted to investigate the ginseng crop disorder-related miRNAs and their target genes for the sustainability of the ginseng industry. A total of 376 miRNAs were obtained from all the tissue samples of the Continuous Cropping obstacles (CCO) and Control Check (CK). 121 miRNAs were found to be differentially expressed in the ginseng. Then, the target genes of differentially expressed miRNAs were enriched and found to be involved in phytohormone-related regulation, MAPK signaling pathway - plant, amino and nucleotide sugar metabolism, and monoterpene biosynthesis, suggesting that the alteration of these related pathways may play a key role in causing ginseng crop disorder. Finally, the correlations between miRNAs and mRNAs were integrated to construct the corresponding reciprocal networks and discover the miRNAs that might play a key role in causing ginseng crop disorder. osa-MIR818d-p3_1ss1TA and pgi-MIR6135i-p3_1ss11TG and pgi-MIR6140c-p5_1ss12CT were found to be at the core of the network, and it was hypothesized that these miRNAs play an important role in the formation of ginseng continuous cropping obstacle.
. 连作障碍问题严重制约了人参产业的发展。鉴于目前对人参作物病害发生机制的研究较少,本研究旨在研究人参作物病害相关mirna及其靶基因,以促进人参产业的可持续发展。从连作障碍(CCO)和对照检查(CK)的所有组织样本中共获得376个mirna。在人参中发现了121个mirna的差异表达。随后,我们富集了差异表达mirna的靶基因,发现它们参与了植物激素相关调控、MAPK信号通路-植物、氨基和核苷酸糖代谢以及单萜类生物合成,提示这些相关通路的改变可能是导致人参作物失调的关键因素。最后,整合mirna和mrna之间的相关性,构建相应的互惠网络,发现可能在人参作物病害中起关键作用的mirna。发现osa-MIR818d-p3_1ss1TA和pgi-MIR6135i-p3_1ss11TG和pgi-MIR6140c-p5_1ss12CT位于该网络的核心,推测这些mirna在人参连作障碍的形成过程中发挥重要作用。

. Rice drip irrigation cultivation is an efficient water-saving cultivation technique. However, it is a special water environment for rice, which makes rice vulnerable to water shortage during the whole growth period or at a certain stage. In this study, five water treatments were set up: drip irrigation regimes (DI), water deficient irrigation for 15 days at panicle differentiation stage (T1), booting stage (T2), flowering stage (T3) and grain filling stage (T4). Results indicated that the T1 treatment reduced the yield most, about 30.6% lower than that in DI treatment. T1 treatment significantly decreased the number of secondary branches and grains per panicle. The T2 and T3 treatment reduced the seed-setting rate of rice and led to yield reduction. The grain weight of grains on bottom secondary branches in T4 treatment was significantly decreased. Overall, In the drip irrigation management, further water shortage at different growth stages will lead to a reduction of yield. Therefore, in production practice, it is necessary to ensure adequate irrigation (soil water content kept 90% of the field water capacity at least) from the beginning of reproductive growth, especially in panicle differentiation stage. This provides a direction for breeding and water management under drip irrigation.
。水稻滴灌栽培是一种高效的节水栽培技术。然而,这对水稻来说是一个特殊的水环境,使得水稻在整个生育期或某一阶段都容易缺水。本试验设置了滴灌、穗分化期(T1)、孕穗期(T2)、开花期(T3)和灌浆期(T4)亏水灌溉15 d 5种水分处理。结果表明,T1处理的产量降幅最大,比DI处理降低了30.6%。T1处理显著降低了次枝数和每穗粒数。T2和T3处理降低了水稻的结实率,导致产量降低。T4处理下次枝籽粒重显著降低。总体而言,在滴灌管理中,不同生长阶段进一步缺水将导致产量下降。因此,在生产实践中,从生殖生长开始,特别是在穗分化阶段,必须保证充足的灌溉(土壤含水量至少保持田间水量的90%)。这为滴灌育种和水管理提供了方向。

. Larix kongboensis is a tree species indigenous to Tibet and sometimes mistaken for L. griffithii . At present, the population of L. kongboensis is dwindling as a result of urban growth. This experiment intends to determine the responsive connection between L. kongboensis standard chronology and climate change using analysis methods in tree-ring climatology and combining them with climate change features of the study region. This correlation study was undertaken to determine whether a “differentiation impact” on the radial development of L. kongboensis exists before and after the climatic change. We also aim to verify if a clear difference is observed between the radial orientation of L. kongboensis and weather conditions at two different heights. Combined with the tree-ring climatology method, Mann–Kendall test was used to assess the timing of abrupt temperature changes in the study region by cross-referencing the L. kongboensis standard chronology (STD). We also utilized sudden temperature change as the dividing line to explore the response connection between L. kongboensis and limiting influencing elements in the research region by comparing the degree of response of climatic factors to the radial growth of L. kongboensis before and after the abrupt change. We examined how the radial growth of L. kongboensis changed as a result of climate variables after rapid climate changes using moving correlation. We then compared the differences between different altitudes. The findings of the correlation analysis are presented as follows: (1) The radial growth of L. kongboensis was severely constrained by the maximum temperature in the early part of the growing season and the correlation between the radial growth from February to June of the same year and the maximum temperature changed from a positive correlation (P > 0.05) to a significant negative correlation (P < 0.05) after the abrupt shift in temperature. The minimum temperature changed from a mostly negative correlation to a mostly positive correlation. Precipitation and relative humidity were significantly more suppressed than those before the abrupt temperature change. (2) Moving correlation demonstrated that the negative reaction of the maximum temperature to the radial development of trees of both species increases in L. kongboensis in both research sites during the growing season, particularly in the early stages of the present growing season. (3) Lower-elevation radial development was hampered more than higher-elevation radial development, with precipitation exerting a significantly greater impact at higher elevations. Results indicated that the response of radial development to climatic conditions for the same tree species in two distinct environments differs significantly. The influence on the radial development of trees is neither completely prevented nor accelerated and “divergence problems” are observed in various months when a sudden temperature change occurs.
. 孔波落叶松(Larix kongboensis)是一种原产于西藏的树种,有时被误认为是L. griffithii。目前,由于城市的发展,孔波树的种群数量正在减少。本实验拟利用树木年轮气候学分析方法,结合研究区气候变化特征,确定孔柏标准年代学与气候变化的响应关系。本研究旨在探讨气候变化前后对孔波草径向发育是否存在“分化影响”。我们还旨在验证在两个不同高度是否观察到孔波草径向方向和天气条件之间的明显差异。结合树木年轮气候学方法,采用Mann-Kendall检验,交叉参考孔波松标准年表(STD),评估研究区温度突变的时间。我们还以温度突变为分界线,通过比较气候因子对空桦树径向生长的响应程度,探索研究区空桦树与限制影响因子之间的响应联系。利用移动相关分析了快速气候变化后,孔柏树径向生长随气候变量的变化规律。然后我们比较了不同海拔之间的差异。相关分析结果表明:(1)空柏树的径向生长受到生长季前期最高温度的严重制约,同年2 ~ 6月径向生长与最高温度的相关性由正相关(P < 0.05)变为显著负相关(P < 0.05)。最低气温由负相关转为正相关。降水和相对湿度受到的抑制明显大于温度突变前。(2)移动相关分析表明,两个研究点的最高温度对两树种树木径向发育的负反应在生长季中都有所增加,尤其是在本生长季的早期。(3)低海拔径向发展受到的阻碍大于高海拔径向发展,且降水对高海拔径向发展的影响显著大于高海拔径向发展。结果表明,同一树种在两种不同环境下径向发育对气候条件的响应存在显著差异。对树木径向发育的影响既不能完全阻止,也不能加速,在发生突然温度变化的各个月份观察到“发散问题”。

The findings of the correlation analysis are presented as follows: (1) The radial growth of L. kongboensis was severely constrained by the maximum temperature in the early part of the growing season and the correlation between the radial growth from February to June of the same year and the maximum temperature changed from a positive correlation (P > 0.05) to a significant negative correlation (P < 0.05) after the abrupt shift in temperature. The minimum temperature changed from a mostly negative correlation to a mostly positive correlation. Precipitation and relative humidity were significantly more suppressed than those before the abrupt temperature change. (2) Moving correlation demonstrated that the negative reaction of the maximum temperature to the radial development of trees of both species increases in L. kongboensis in both research sites during the growing season, particularly in the early stages of the present growing season. (3) Lower-elevation radial development was hampered more than higher-elevation radial development, with precipitation exerting a significantly greater impact at higher elevations. Results indicated that the response of radial development to climatic conditions for the same tree species in two distinct environments differs significantly. The influence on the radial development of trees is neither completely prevented nor accelerated and “divergence problems” are observed in various months when a sudden temperature change occurs.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
