They have been housing eucalypts crops for wood production. Their management, together with green manure inoculated with symbiont microorganisms, can increase the efficiency of nutrient uptake and reduce the need for chemical fertilization. The aim of the present study is to assess the growth and uptake of macronutrients by Eucalyptus grandis seedlings grown in substrate from clay extraction sites, based on intercropping system farming, with green manure inoculated with rhizobia and/or arbuscular mycorrhizal fungi (AMFs). The experiment followed a completely randomized design, with three repetitions, and the following treatments: cultivation of eucalypt (no intercropping) inoculated, or not, with AMFs; eucalypt intercropping system with Canavalia ensiformis Lam. or Canavalia brasiliensis Mart ex Benth., inoculated, or not, with AMF´s and/or rhizobia. Isolates of the symbiont microorganism were collected from spontaneous plants grown in clay extraction-site soils. Eucalypt seedlings and green manure were grown, together, in 6 L pots filled with substrate from clay extraction sites. Green manure shoot was cut 45 days after cultivation and eucalypt was harvested 60 days after it. Results: Inoculation with AMF´s+ rhizobia reduced the C:N ratio and increased N and P acquisition by C. ensiformis. Conclusions: Inoculation of native AMFs from the clay extraction site was effective in boosting the growth and nutrient acquisition of eucalypt plants grown in this substrate, in cultivation intercropped, or not, with C. ensiformis or C. brasiliensis. It also reduced visible symptoms of nutritional deficiency. Ca, Mg and K concentration in eucalypt plants was not changed by green manure cultivation or by inoculation with AMFs or rhizobia.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135260823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals do not quickly disappear and do not decay in nature; they accumulate in plant organs and indirectly affect human and environmental health. On the other hand, some elements are essential for plant growth, but some have poisonous or carcinogenic consequences, even at small concentrations. Thus, determining and observing heavy metal concentrations in the atmosphere is crucial., Plants are the utmost important indicator of heavy metal concentration changes in the air and are called biomonitors. The current study aims to determine the variation in some elements (K, P, Fe, Zn, Cu, Cd, and Cr) concentration inPicea pungensEngelm. (valued for its bluish or silvery-gray foliage) grown in the Ankara city center (capital of Türkiye and second crowded city), based on the plant needles and the age of the branch. Thus, this study tried to determine the potential of using needle leaves and branches ofP. pungens as a biomonitor to determine some heavy metal concentrations. Results: The heavy metal concentrations significantly differed by organ and organ age. The element levels were higher in the branches in some years and the needles in some years. Conclusions: This result indicates that Picea pungens needles and branches are suitable for observing studied heavy metal concentrations. Using branches and needles does not also harm the plant species.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135261458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a cold-tolerant tree species which also faces heat stress during summer. In the current study, RNA-Seq profiling of two-month-old B. platyphylla seedlings were conducted utilizing the MGISEQ-2000 platform. Results: In total, 856,347,961 clean reads were obtained from 26 RNA-Seq libraries. Totally, 822,552,820 reads were successfully mapped to B. platyphylla reference genome. Further, a total of 360 and 264 DEGs were discovered under cold and heat exposure, respectively, while a total of 104 DEGs were identified under both cold and heat exposure. It was found that several pathways including response to cold, response to heat, response to temperature stimulus, response to stress, lipid metabolic, jamonic acid and ethylene, even developmental processes were significantly enriched in GO enrichment analysis of cold and heat stress in biological process term. Several transcription factors (TFs), including MYB66, CBF2, bHLH96and bZIP7 take a pivotal role in response to temperature stresses. Furthermore, heat shock proteins were identified under cold and heat stress, respectively, suggesting these genes participate in reducing cold and heat stress detrimental effect by interacting with TFs or other genes related to abiotic stresses, chlorophyll and photosynthesis, osmoprotectants, and phytohormone as well. Conclusion: This study not only underlying B. platyphylla’ s molecular mechanism in response to temperature stresses but also provides candidate genes involved in response to temperature stresses.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135316886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Floristic and phytosociological studies are fundamental database for many studies of conservation and sustainability, but there is a knowledge gap concerning TDFs, especially in the Andes valleys. The aim of this study was to determine the phytosociological structure and composition of woody vegetation of seven TDFs in the Colombian Andes, and because the flora associated with this type of forest has a geographical distribution restricted to each locality where this biome exists, provide information on the main species, genera and families for conservation and restoration actions as well as for future meta-analyses. We sampled seven TDFs with 20 plots of 25 m × 4 m. Results: In the 1.88 hectares of samples, 8422 individuals were surveyed, distributed in 170 species, 120 genera and 50 botanical families. Of these species, 78.82% were identified at the species level, 17.05% at the genus level, and 4.11% at the family level. The most important families were Fabaceae and Myrtaceae. Nitrogen-fixing Fabaceae species were prominent amongst the important species, especially in low altitude and more stressing sites. Conclusion: The structure, composition and ecological importance of these forests must be considered for conservation and ecological restoration plans, in particular the habitat preference of species along the topographic gradient. Particularly noteworthy for conservation are the Myrtaceae species because promote connectivity and regeneration by providing resources for the fauna, a driver of dispersal, as well as nitrogen-fixing Fabaceae species, because promote the resilience and natural regeneration of TDFs in the Andes, a key feature of stability.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135261255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For each batch, we determined seed water content and initial germination. To evaluate temperature effects, we tested seed germination. After, we generated the imbibition curves for the two provenance. To evaluate the loss of DT, the seeds were left to germinate along different time intervals. We monitored water loss by regularly weighing the seeds until achieving stabilization, keeping them under these conditions for 72 hours. After drying, the seeds were pre-hydrated and submitted to the germination test. Results: We identified variations in physiological characteristics between the seeds from north and southeast batches. At the temperature extremes, the seeds from both provenance failed to germinate. The highest germination percentages were observed at 20 and 25 °C (constant) and between 20-30 °C (alternating) for the two batches and, for the southeast batch specifically, at 30 °C. The imbibition curve displayed a triphasic pattern with a rapid increase in seed fresh weight in the first 48 hours. Conclusion: The southeast provenance seeds lost DT abruptly, until its complete loss after radicle protrusion, which occurred in both batches. The highest values of germination speed index (GSI) of both provenance were observed after a 9-day imbibition period, suggesting seed hydration memory. Drying resulted in necrosis of the root tissue and death of the seeds with visible roots.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67155006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
