Mineral supplementation and productivity of the Shiitake mushroom on eucalyptus logs. Brazilian reports on Shiitake mushroom [ Lentinula edodes Berkeley Pegler] productivity grown on Eucalyptus saligna Sm. The current production on this kind of wood is, however, low and variable. Mineral fertilization was carried out when the logs were submerged in water to induce fruiting bodies, using the following saline concentrations: Mineral fertilization increases the productivity provided that the logs are well colonized by Shiitake mushrooms.
Lentinula edodesnitrogen, phosphorus. The Shiitake mushroom, in Brazil, has been cultivated almost exclusively on eucalyptus logs due to their lower exigency in terms of cultivation installations and handling.
On the other hand, there are frequent producer complaints regarding low and inconsistent yields which have caused many of them to abandon their activities or find alternative cultivation on heat-treated particulate substrates such as axenic media. The brazilian literature regarding production of Shiitake on eucalyptus logs is optimistic in that logs, 12 cm in diameter, produce up to 1. This excessive of optimism, resulting from the lack of scientific background and from the extrapolation of data obtained in other countries using other types of wood, has included the generalization that cultivation of Shiitake on logs is low cost and has a rapid financial return.
These extrapolations, however, do not support the fact that eucalyptus logs are not associated with uniformity in production Montini, ; Andrade, ; Teixeira, Some logs with mean diameter of 10 cm and length 1 m produced g of fresh mushrooms per log in the first harvest but, others did not reach this productivity, as suggested in the literature Montini, Shiitake productivity is related to climatic conditions and the interaction among lines and species of eucalyptus Teixeira, The level of contamination of the logs is another factor that affects yield Andrade, In addition to sanitary problems in Shiitake cultivation, the eucalyptus, when cultivated in low-fertility soil, can produce a wood that is poor in nutrients, important for the development of Shiitake.
Another important aspect is the number of eucalyptus cuts, since the older the cut, the poorer the wood, due to soil exhaustion in the course of conducting the forest Barros, The objective of shiiatke research was to evaluate mineral-supplementation interactions for the cultivation of the edible mushroom Shiitake, aiming to attenuate nutritional shiitakr of eucalyptus wood, which has an impact on the yield of this mushroom. The inoculant or “seed” of L.
Interactions of mineral supplementation two rates and a control fe were evaluated for three lines of the Shiitake mushroom and, after six months of incubation, fruitification was stimulated artificially in immersion tanks of contents supplemented with minerals. Minerals were supplied, at the following levels: For this procedure, together with the induction of mineral supplementation, the nutrients were dissolved in water and added to the immersion tank.
The concentration of carbon dioxide gas was maintained between and m L mL The following production phases were cuotivo by the same method after varying periods of inactivity for the logs: Productivity is defined as the yield of wet biomass of mushroom g per kg of dry log in four accumulated production frutings.
The dry mass of the logs was determined through the basic density of the wood, and the log’s mean diameter and length. The basic density of the wood is defined as the relation between the mass of an oven-dried sample and its displaced volume in water.
This was determined with a hydrostatic balance ABNT,to measure samples of 50 logs of virgin wood non-degraded wood was used to evaluate the initial basic density, Dbi, in t m With the wet volume of the logs, the mass of the initial dry log Mtsi kg was calculated as: The sawdust was obtained from the same population of experimental trees, from recently-cut logs in the field.
The extract was obtained from this dust by infusion in mL of boiling water for 30 minutes followed by filtration through cotton fabric resulting mL of extract.
After filtration, mineral supplementation of the sawdust extract was made with the following treatments: Evaluation was made daily at the same hour to register the radial growth until the fungus mycelium reached approximately 0. In the final fruting of the experimental production on logs, mushroom samples from all treatments were submitted to a Weende-scheme chemical analysis.
For productivity, non-parametric analysis of variance and the Kruskal-Wallis test were utilized. For mycelial growth, parametric analysis of variance was run using F-test, with data from the fifth day after inoculation.
For the first fruiting, productivity was negligible; even after six months of incubation only a few logs showed signs of colonization with spontaneous fruitification. This may be related to the substrate culture since the amount of nutrients in the logs from the seventh cutting did not allow for extensive colonization of the log by Shiitake, increasing the fruitification period in comparison to logs from the first or second cutting.
For the second and third fruitings the accumulated mean productivities were low. After four fruitings the accumulated mean productivity increased considerably Figure 1and significant interaction occurred between lines and rates of mineral supplementation.
This reinforces the hypothesis of late production, obtained in the present work, possibly due to the low nutrition level of the seventh cutting of eucalyptus cultivated on non-fertilized soil.
This suggests that the colonization of exhausted logs depends on the aggressivity of the line and its competitiveness with the ambient microbiota. In the present work, until the third fruiting these periods were less than 60 days, since reduction of the periods among production phases as a function of mineral supplementation was expected.

Late production may have been due to the scarcity of nutrients in the logs treatment without mineral supplemenationassociated with the time needed for mineral supplementation to be effective.
It was shiitae that the responses would be immediate with mineral supplementation in the immersion bath and, probably would have a cumulative effect.
Shiitake cultivation on heat-treated enriched sawdust with sugar-cane Saccharum officinarum L. Shiitae results from the experiment to evaluate radial growth of Shiitake ratified this hypothesis since under axenic laboratory conditions, all lines responded to mineral supplementation at two concentrations, 0.
Many producers attribute the delay in fruitification and low productivity to the poor quality of the inoculant. However, the species of eucalyptus that was cultivated, the soil or the fertilizer used for eucalyptus forest are often unknown.

Also unknown is the number of cuttings undergone by the trees since their planting, ignoring the importance of wood substrate in relation to productivity. This was evidenced in the present work, in which greater production occurred only in the fourth se, days after inoculation of the logs. This long period is mainly due to the wood substrate logs from the seventh cuttingnutritionally poor for Shiitake, but satisfactory for competitors.
On the other hand it must be remembered that for commercial cultivation the inoculant can be contaminated or may have lost shiitaoe fruitification properties. Mineral supplementation increased the protein content of Shiitake Figure 4 and Table 3as a direct function of increasing rates of mineral supplementation.
