Introduction: In the nursery, controlled-release fertilization and inoculation with mycorrhizal fungi promote the quality of plant material reproduced in containers. Objective: To evaluate the effect of two commercial mycorrhizal inoculants and one controlled-release fertilizer on the development of Pinus engelmannii Carr. in nursery. Materials and methods: Two commercial inoculants (fungi native to Mexico [1 mL·plant-1 with 1.05 x 107 spores·mL-1] and exotics [1.5 mL·plant-1 with 6.5 x 106 spores·mL-1]), two doses of a controlled-release fertilizer (11-28-11 NPK [3 and 6 g·L-1]) and a control were evaluated; in total, nine treatments were used. The variables analyzed were: survival, stem height, root collar diameter, wet and dry biomass, ratio of dry biomass of the aerial part/dry biomass of the root part, lignification index, Dickson’s quality index and mycorrhizal colonization. Results and discussion: Survival (80 to 96 %) was similar between treatments. Eight months after sowing, seedlings showed significant differences (P ≤ 0.05) in morphological variables; combined treatments gave better results. Plants with commercial inoculum of native fungi (1 mL·plant-1 [Amanita rubescens Pers., Amanita sp., Lactarius indigo [Schwein] Fr., Ramaria sp. and Boletus sp.]) and fertilization of 3 g·L-1 had higher Dickson quality index. It was observed that the higher the fertilization dose, the lower the percentage of mycorrhizal colonization. Conclusion: The combination of ectomycorrhizal inoculum of native fungi and low-dose fertilization showed that both components are complementary in the plant development of P. engelmannii.

Introduction: Bibliometric analysis is a quantitative tool for recognizing trends and research gaps in topics of scientific interest. Objective: To identify progress in scientific production, collaborative networks, research issues and application of models of temperate forest management (MTFM), on a global scale, in relation to management, productivity, carbon storage and nutrient cycling. Materials and methods: The review focused on the collection of data from the Web of Science Core Collection platform in the period 2005-2019. Results and discussion: The bibliometric analysis made possible to collect 960 specialized scientific articles on the topic, from journals indexed in Journal Citation Reports (JCR). The institutions with the greatest academic authority in forest management studies were Natural Resources of Canada (NRCan), Institut National de la Recherche Agronomique (INRA) and US Forest Service. MTFM topics focused on forest plantation growth, effects of forest practices on structure, productivity, carbon sequestration and, to a lesser extent, nutrient availability. Mexico showed low collaboration with other institutions and a forest approach in the application of models. Conclusions: The analysis helped to guide research on MTFM in Mexico. The implementation of models is recommended to achieve forest harvesting based on an integrated understanding of the system and thus provide sustainability.

Introduction: The forest management unit 0807 (UMAFOR 0807) is one of the most productive in timber and water resources provision, but there are no studies of historical hydroclimatic variability and its trends for predictive purposes. Objective: to generate a precipitation reconstruction through a regional dendrochronological network for the southwest of the state of Chihuahua. Materials and methods: a network of growth series of five distinctive conifers of UMAFOR 0807 was developed; through Principal Component Analysis the series with the greatest common variance were defined to obtain a representative chronology. The reconstruction model was generated with a series of regional precipitation. The general circulation modes with the greatest impact on rainfall variability and the association of the total ring-width index with the drought indices were analyzed. Results and discussion: From eight chronologies generated, six showed a common climate response to integrate a regional representative series, which responded to September-July precipitation. The correlation between the total ring-width index and the Palmer Drought Severity Index (PDSI) was 0.68 (P < 0.01) in the June-August period, and 0.71 (P < 0.01) for the Standardized Precipitation Evapotranspiration Index (SPEI) for August of the previous year to June of the current year of growth. The reconstructed precipitation showed significance in spectral peaks of 2.1 and 2.8 years, corresponding to the influence of ENSO (El Nino–Southern Oscillation). Conclusions: the dendrochronological network composed of various tree species and integrated in a regional chronology allowed to capture the interannual and multiannual variability of the climate.

Introduction: Wood is susceptible to be used as a carbon source by fungal species damaging the wood. Its durability has been categorized according to its weight loss, without taking into account the decrease in the inherent physicochemical and mechanical properties. Objective: To evaluate how how weight loss affects the physicochemical and mechanical properties of Pinus pseudostrobus Lindl. wood exposed to brown-rot fungi Gloeophyllum trabeum (Pers.) Murrill. Materials and methods: Sawn timber pieces of P. pseudostrobus were inoculated with 50 mL of G. trabeum (106 UFC∙mL-1). Periodically (zero, three, six and nine months) and with the help of a universal testing machine, parallel compression (PC), static bending (SB) and perpendicular compression to the grain (CPG) were evaluated, and holocellulose, cellulose and lignin were quantified. Results and discussion: After nine months of interaction with G. trabeum, the pieces of wood were resistant to degradation, taking into account only weight loss. However, the chemical-mechanical properties evaluated showed that the fungus produced thinning and rupture of the tissue cells causing significant decrease in SB (100 to 56 N∙mm-2) and CPG (42.2 to 20.2 N∙mm-2), which reduced its resistance to mechanical stress. Conclusions: Wood exposed to fungal degradation is significantly affected in its mechanical properties, disqualifying it for construction. The damage is not reflected in the aesthetics of the material, which is surprising, since the common user of pine wood would not be able to notice the problem.

Introduction: The establishment of new crops may cause climatic alterations at the local or regional level. Objective: To analyze temperature and rainfall variation by simulated replacement of current vegetation through the introduction of sugarcane (Saccharum officinarum L.), jatropha (Jatropha curcas L.) and moringa (Moringa oleifera Lam.) in the central region of the state of Veracruz, Mexico. Materials and methods: Simulations of environmental temperature and rainfall for each crop and the control (current conditions: mixed crop, perennial trees, mixed forest and irrigated agriculture) were made with the Regional Climate Model (RegCM4). The model was evaluated by comparative analysis between simulations and observed data, using the mean square error and the root-mean-square error as measures of dispersion. Results and discussion: Regions with soils devoid of natural vegetation, such as agricultural soils, would have greater climatic variability. In these soils, the displacement of current vegetation by sugarcane would generate the greatest thermal alterations with a decrease of 0.7 °C, while with jatropha and moringa, the decrease would be 0.3 °C. Regarding rainfall, the RegCM4 bias increases when there are high variations in elevation, thus other models should be explored. Conclusions: The introduction of moringa or jatropha for bioenergy purposes would be a low climatic impact alternative, while sugarcane is not considered suitable for these purposes due to the greater climatic impact that it would have in the region.

Introduction:Jatropha curcas L. is a species native to Mexico that has recently been considered an important crop to produce biofuel. Objective: To isolate and identify rhizobacteria from J. curcas with antagonistic activity against phytopathogenic fungi (Curvularia lunata and Fusarium equiseti) of this crop and evaluate their capacity to promote tomato plant growth. Materials and methods: The isolates were obtained by serial dilution and antagonistic activity was assessed by volatile and diffusible compounds on PDA medium. In addition, the production of antifungal compounds and metabolites that promote the plant growth were determined. The isolates were identified by amplifying the 16S RNA and sodA genes. Finally, the isolates were inoculated on tomato seeds to evaluated plant growth promotion and germination. Results and discussion: The antagonistic bacteria were identified as Bacillus mojavensis, Bacillus subtilis, Bacillusthuringiensis, and Pseudomonas aeruginosa. The antifungal effect on the mycelial growth of C. lunata and F. equisetiwas due to the presence of volatile and diffusible compounds with between 30 % and 79 % inhibition. Pseudomonas aeruginosa showed the strongest inhibitory effect (48.7 to 79.8 %). Bacillus subtilis (A1), B. mojavensis (A4) and B. thuringiensis (A6, A8) showed the highest germination (70 % to 88 %). The vegetative growth of tomato plants treated with the isolates was significantly higher than the controls(P < 0.05). Conclusion: Eight rhizobacteria isolated from J. curcas showed antagonistic activity against C. lunata and F. equiseti and demonstrated their capacity to improve the germination and promote growth in tomato plants

Pseudomonas aeruginosa showed the strongest inhibitory effect (48.7 to 79.8 %). Bacillus subtilis (A1), B. mojavensis (A4) and B. thuringiensis (A6, A8) showed the highest germination (70 % to 88 %). The vegetative growth of tomato plants treated with the isolates was significantly higher than the controls(P < 0.05). Conclusion: Eight rhizobacteria isolated from J. curcas showed antagonistic activity against C. lunata and F. equiseti and demonstrated their capacity to improve the germination and promote growth in tomato plants","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":"27 1","pages":"181-198"},"PeriodicalIF":0.6,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45873484","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}
