Objective: To determine the influence of bud origin, rootstock fertilization, grafting period and grafting techniques on the success of grafting, growth, and survival of intraspecific grafts in Pinus pseudostrobus var. oaxacana (Mirov) Harrison. Materials and methods: The effect of four factors was evaluated ([a] two bud sources, [b] three rootstock fertilization doses, [c] three grafting seasons and [d] two grafting techniques) on the success of grafting, shoot growth (Sg) and survival. An analysis of variance was carried out to determine the effect of factors a, b, c, and d on successful grafting and Sg, and a Log-Rank test was carried out for survival analysis. Results and discussion: Significant differences (P ≤ 0.05) were obtained for factors a,c and d. Grafting during winter (December 2018 and February 2019) using the side-veneer grafts technique and buds coming from Santa Catarina Ixtepeji showed the highest values of successful grafting (≥25.5 %), Sg (≥14.5 cm) and survival (≥20.5 %). Final survival decreased from 100 to 27 % 90 days after grafting. Conclusions: Grafting period, bud origin, and grafting technique, individually or interacting with, are determinant factors for the success of intraspecific grafting on P. pseudostrobus var. oaxacana.","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48494659","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}

Objective: To study the effect of livestock on the early stages of regeneration of a queñoa (Polylepis australis Bitt.) forest. Materials and methods: Within a pure forest of P. australis at Parque Provincial Potrero de Yala, Jujuy, Argentina, densities of seedlings (˂1 year) and saplings (˃1 year and ˂30 cm) were measured in the presence (0.23 heads∙ha-1) and absence of livestock, for a year. Linear mixed models(normal distribution) were adjusted for density of seedlings and saplings. Data was analyzed with a Chi-square test (X2). Results and discussion: Presence of livestock had no impact on seedling density, but significantly decreased density of saplings (P < 0.001); in areas without livestock (10.58 ± 6.64 individuals∙m-2) was three times higher than with presence of livestock (3.17 ± 3.86 individuals∙m-2). Difference in density of seedlings and saplings was significantly (P < 0.001) over time. This indicates that there is potential for natural regeneration, but livestock would affect stages after seedling emergence, representing a threat to the forest. Conclusion: This study provides important information on livestock management in mountain forests of P. australis. A long-term study of the effect of livestock on seedling and sapling density, and over the entire distribution range, is needed.","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43078385","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}

Objective: To determine productive potential, dispersal distance and seed bank of Lupinus montanusKunth (lupine) at the upper limit (4 200 m) of its natural distribution at the “Nevado de Toluca” mountain. Materials and methods: The seed bank was estimated in an area of 1.88 m2. Three sampling sites were established with plants in reproductive stage (15 plants) isolated from other adult plants. Seed production was determined in traps placed at the four orientations of each plant and spatial pattern of dispersal was also determined. Results and discussion: Seedbank density was 4.26 seeds∙m-2 of soil. Lupinus montanus produced over 5 500 seeds per plant in one reproductive cycle; its seed potential was associated with plant height and number of stems. The number of seeds collected varied significantly (P < 0.0001) with respect to distance from the mother plant. The dispersion curve was adjusted (P < 0.01) to a negative exponential model (R2 = 0.849). Dispersal in the four orientations was symmetrical; 97 % of the seeds fell at a distance ≤2 m from the mother plant. Conclusions: Only 3.2 % of the seeds of L. montanus reached a distance greater than 2 m from the mother plant; however, dispersal is uniform in all orientations, therefore soil slope does not represent a limiting factor for the altitudinal migration of species.","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42621451","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}

Objective: To quantify the growth and phytochemical and nutrient content of S. pilosa plants in situ under three edaphoclimatic conditions in the state of Hidalgo, Mexico. Materials and methods: At the three sites called Huasca de Ocampo (HO), Mineral del Chico (MCh) and Mineral del Monte (MM), with different climates, soil types and elevation ranges, soil was collected and three plant samplings were carried out to follow the development of the species. Results and discussion: The number of plants varied according to the sampling sites, being higher in MCh (12 plants·m-2). Growth rate and leaf area were directly related. In MCh and MM plants, net photosynthesis only supplied the demand in the first two samplings, where there was significant accumulation (P ≤ 0.05) of matter, while in HO it supplied all the samplings. MCh and HO plants had a higher nutrient concentration (P ≤ 0.05). MCh and MM plants showed a higher concentration of phenols and flavonoids, and HO plants stood out in total terpenes.

Indicators recurrently include qualitative attributes for which there are few studies assessing the level of compliance. Objective: To apply a multigranular approach, based on the 2-tuple fuzzy linguistic model, to evaluate 13 indicators of the National Forestry Program, established in the system of social policy indicators derived from the National Development Plan 2012-2018 of Mexico. Materials and methods: The method uses the 2-tuple fuzzy linguistic representation model and an extension called extended linguistic hierarchies, designed to solve problems with multigranular linguistic information. The indicators’ level of compliance was evaluated based on four criteria: clarity, relevance, monitoring, and adequacy. Results and discussion: The structure defined in evaluating social policy indicators corresponds appropriately to that used with the 2-tuple fuzzy linguistic model. The evaluation resulted in a sorted list in which the indicator “Rate of change of timber forest production” had the best rating with a “very high” level of compliance; 10 other indicators had the “high” level of compliance, and the remaining two indicators were rated with “moderate” compliance.

Objectives: To model the ecological niche of the forage species Chloris gayana Kunth and Eragrostis curvula (Schrad.) Nees, and the conifers Pinus devoniana Lindley, Pinus lawsonii Roezl ex Gordon and Pinus montezumae Lambert and to identify potential areas for silvopastoral systems. Materials and methods: The ecological niche was modeled based on data from georeferenced collection sites in Mexico and 23 environmental variables. Subsequently, areas were identified and the extent, where forage species converge with conifers in both agricultural and forest areas, was estimated. Results and discussion: Potential areas for silvopastoral systems with the five species were found mainly in the Neovolcanic Axis and the Sierra Madre del Sur, with a greater area suitable for agricultural areas compared to forestry areas. The ecological niche models had high predictive capacity with an area under the curve values greater than 0.93. Altitude and annual temperature range were the most important variables. Pinus devoniana had the largest potential area to be intercropped with C. gayana and E. curvula.
