In Mesoamerica, this forest is among the most threatened by anthropogenic activities, which makes necessary agricultural practices that incorporate local germplasm preservation. We propose the propagation with stakes of Bursera copallifera, B. fagaroides, and Ipomoea pauciflora, three tree species of the tropical dry forest of Morelos, Mexico. We evaluated if stake survival was related to their diameter, height, and leave's presence for each tree species in a one-year greenhouse experiment. After one year, 79%, 39%, and 9% of the stakes of B. fagaroides, B. copallifera, and I. pauciflora became established, respectively. Only the leaf's presence influences stake survival. The propagation of stakes is a highly viable method for the two Bursera species. With stakes, peasants can develop live fences inside agricultural fields, preserve local germplasm, and simultaneously, the ecological interactions and the ecosystem functions of the species in the landscape. Our work contributes original and transferable knowledge for the vegetative propagation of tree species of the tropical dry forest. This knowledge can help with the conservation of the tropical dry forest and the sustainable management of tree species with ecological and cultural importance.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"220 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79833050","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}

Out of these microorganisms, particularly from the species of the genus Streptomyces, most of the antibiotics that are used for human health have been characterized and identified. However, they are seldom used as antagonists in agricultural systems; despite it is plausible that species of Streptomyces can control important root pathogens. The objective of this study was to obtain the molecular identification and characterization of three Streptomyces strains by confronting them against phytopathogenic fungi and oomycetes, in order to determine the in vitro antagonistic potential and the effect of volatile compounds produced. The strains of Streptomyces were molecularly identified through the sequence of 16S of the RNAr such as: Streptomyces mauvecolor (B21), Streptomyces lasiicapitis (B22) and Streptomyces olivochromogenes (B37) which showed antagonistic potential in vitro against Rhizoctonia solani, Fusarium oxysporum and Phytophthora capsici. S. mauvecolor showed an average percentage of radial growth inhibition (PICR) for the three pathogens of 62.88 %, S. lasiicapitis of 98.72 % and S. olivochromogenes of 83.58 %. Similarly, out of the three pathogens, R. solani was inhibited in greater proportion by the three strains (93.85 %). A relevant fungistatic action was observed over P. capsici, an economically important oomycete, with 100 % inhibition at 24, 48 and 72 h of exposure with S. lasiicapitis, first reported as antagonist of root pathogens. The use of these species of Streptomyces with high levels of antagonism against pathogens of economically important crops, represents an alternative of low environmental impact.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"10 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85346333","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}

Under the hypothesis that replacing alfalfa (lucerne) with dry brewer grains (DBG) for lactating ewes would modify their milk production and physicochemical quality. The aim was to determine the effect of the DBG supplementation in the feed of ewes in milk production and quality, as well as in the physical condition of the animals. Fifteen 18-month-old ewes from a cross between Friesian × Rambouillet resulting from a first birth (30 days on milk) were distributed into 3 treatments with 0, 150 or 300 g of DBG. The experiment had a duration of 30 days, in which milk production, feed intake and physicochemical characteristics of the milk (fat, non-fatty solids, density, cryoscopic point, protein, lactose, and salts) were measured and each week the intake of feed in dry mass and the change in body weight were registered. Milk production displayed no differences between treatments and a decrease was observed in the production of milk for all treatments between weeks one (462 mL) and four (162 mL). Physicochemical variables of the milk displayed no differences between treatments, and quality was not affected. The change in body weight was the highest in the 300 g DBG treatment, with a modification of approximately 12.8 ± 0.45 kg (p ≤ 0.05) during the trial time, daily weight gain was 440 ± 0.08 g d-1 (p ≤ 0.05).

It is hypothesized that initial seed weight and scarification would affect the percentage of seed germination of this species. The objective was to compare the effect of initial seed weight (two levels) and scarification treatments (four levels) on in vitro germination of E. parryi. The morphology of seedlings grown for 12 months was also described. Four hundred seeds were divided into two groups of 200 seeds each: first group, seeds of 35 to 45 mg; and second group, seeds of 46 to 55 mg. The scarification treatments were a control (intact seeds), mechanical scarification, application of 25 % sulfuric acid and Murashige and Skoog growing medium added with 2 mg L-1 of gibberellic acid. Fifty seeds per treatment were placed for each weight group. Treatments were distributed in a completely randomized experiment with factorial arrangement. Data were subjected to analysis of variance and means were compared by Tukey’s test (p ≥ 0.05). Results showed significance in the interaction of seed weight and mechanical scarification treatment by obtaining 93.2±3.6 % germination in seeds of 35 to 45 mg and 96.0±3.3 % in seeds of 46 to 55 mg at 30 d of in vitro culture. The morphological description of the seedlings provided information on the development of E. parryi in juvenile stages, which differs from the adult stage. Results on germination and the morphological description of the seedlings represent an important advance for propagation and conservation purposes.

Generally, grafting success is low, therefore, it is required to study the influencing factors. Such as the technique and the contact surface of the cambium that depends on the length of the cut on the scion and the rootstock. The objective of this study was to evaluate graft success, growth, and needle development on Pinus patula grafts as functions of the grafting technique and cutting length. It was expected that a specific combination of technique and cutting length would allow predicting the graft success. The techniques of top cleft, side-veneer and splice grafting were used with three cutting lengths (1.5, 2.0, and 2.5 cm) in a completely randomized design with factorial array. The data were analysed with an analysis of variance and treatment means were compared with the Tukey test (p ≤ 0.05). Sixty days after grafting, technique influenced success; top cleft grafting had the highest value (80%) but was not statistically different from side veneer grafting (73.3%). There was, however, statistical difference between top cleft and splice grafting (56.7%, p ≤ 0.05). There were no differences among the three cutting lengths in terms of the three variables evaluated. The effect of the interaction showed that top cleft and side veneer grafts with the cutting length of 1.5 cm expressed the greatest growth (32.4 and 32.2 mm, respectively); followed by side veneer grafting with the cutting length of 2.0 cm (30.4).

In a randomized complete block design with slope as the block factor and experimental units of 2700 m2 with four replications, the agronomic and nutritional quality characteristics of six treatments were compared: Urochloa hybrid cultivar Mulato II, U. brizantha cultivar Toledo and Megathyrsus maximus cultivar Mombasa, established alone or associated with Canavalia brasiliensis, against the control Dichantium aristatum, a naturalized forage of the region. Mulato II, Toledo and Mombasa alone and in association showed greater (p ≤ 0.05) vigour, height, cover and forage production than the control. Mombasa produced 10.7 Mg ha-1 MS (Megagrams of dry matter per hectare), exceeding (p ≤ 0.05) by 74, 53 and 84 % that were recorded in Mulato II, Toledo and control, respectively. C. brasilienses promoted higher productivity in the association with Mulato II and improved nutritional characteristics in the associations with Toledo and Mombasa compared to specific monocultures and the control. The improved grasses alone or associated with C. brasiliensis were a better forage option than Dichantium aristatum.

In order to measure the effect in the agronomic characteristics of X´mejen Naal maize, an experiment was designed in complete randomized blocks in a bifactorial arrangement with four repetitions, in which three green manures were tested, with or without the inoculation of Fosfonat (endomycorrhizas, EM, plus nitrogen fixating bacteria, NFB). Treatments were Mucuna (Mucuna pruriens, T1=MUC), Xpelón (Vigna unguiculata, T2=PEL), Ibes (Phaseolus lunatus, T3=IBE), inoculated Mucuna (T4=MUCEM), inoculated Xpelón (T5=PELEM), inoculated Ibes (T6= IBEEM) and the control with the incorporated biomass of weeds plus the addition of 200 kg ha-1 of diammonium phosphate (T7=ARDAP). Results showed that there were only differences caused by the types of green manure and their interaction with the inoculated symbionts in the fresh weight or biomass in X´mejen Naal maize.
