Plantaciones Trufas Bio Bio y Malleco

En Junio estamos llevando a cabo el proceso de plantaciones de trufas negras en nuestros campos en la zona de Mulchen, Bio Bio. Actualmente esta zona y Malleco pasan a tener la mayor superficie plantada de Truferas a nivel nacional, completando en total 70 has aproximadas este año.
En esta zona actualmente existen 9 has actualmente que comienzan a producir trufas esta temporada y se espera que prontamente en 2 años será la zona más importante de producción de trufas en Chile.

Truffle Growing Conference in Talca

Chile has established a policy of growth, based on long-term strategy to make the country one the best Food and Forestry Suppliers . However, several studies have established that to achieve this we must solve various productivity gaps and to generate effectively launch beyond this policies. With the purpose of promoting emerging sectors in the Maule Region, and thus support the national strategy , Social Development Corporation Rural Affairs (Codesser) within the Action Plan funded by CORFO, organized the Conference “Challenges and perspectives of truffle cultivation in Chile”, an activity that was held on Thursday July 7 from 9 : 00 hours in Talca. In this opportunity, Ricardo Ramirez spoke on “Current Status of truffle cultivation in Chile and its prospects for development”, the participants became familiar on Truffle growing in Chile, the experience to date, current situation, associated costs, expected economic returns, projections, challenges for the country, planting techniques, marketing, among other issues related to this high delicacy. Important information for those interested in establish plantations, which has great potential, since Chile has climatic and soil conditions to produce exceptional truffles.

New Truffle harvest season in Talca

On Saturday, June 25, was held a tour near Talca city to kick off the new Truffle Season. This plantation is a pioneering and demonstration project of Foundation for Agrarian Innovation (FIA, Ministry of Agriculture of Chile). These results on black truffles Production are the fruit of more than 6 years of applied research, which has successfully demonstrated that truffle growing is feasible around some areas of the country and certainly with a huge potential for future growth as a new and exclusive industry gourmet such as black truffle (Tuber melanosporum).

“Sex War Under Truffle Soils ”

The article published in New Phytologist on the underground distribution of mating types in truffle strains has caused enough press activity in past months. The new coverage grew minute to minute … It’s amazing how this fungus is causing great stir. It is also good that this works reaches a wider audience. Here is the press release: “They are one of the most popular dishes in the culinary world, but now scientists have discovered that strains of black truffles are involved in a war for sexual reproduction in the ground. The research, published in the journal New Phytologist just when the truffle season started in Europe 2010-2011, represents a breakthrough in understanding the reproductive aspects of this fungus, which may be the basis for future crop improvement.
The team, led by Dr. Francesco Paolocci and Dr. Andrea Rubini of the CNR of Italy, the Institute of Plant Genetics of Perugia and by Dr. Francis Martin INRA Nancy, conducted research on strategy reproduction of the prized black truffle, Tuber melanosporum, which grows naturally in southern Europe. During truffle season, between late fall and winter, these fruiting bodies can grow to 7 cm in diameter, and typically weigh up to 100 grams, with a value that is often measured in hundreds of euros.
The fruit is the crucial part of the life cycle of the truffle, which occurs from the mycelium of the fungus interacts with the host plants by colonizing their roots. However, the process that makes this fungus pass from his vegetative state (mycelium and mycorrhizal development) to state their reproductive status (the same nose. Fruit of the fungus) is still unknown.
“It was commonly believed that truffles, like other fungi, are homotallic, meaning that they reproduce without a partner (processes of self-fertilization). It was also believed that the truffle was based only on the environment and nutrition, but we know this is not true. “
The use of information provided by the project to sequence the genome of Tuber melanosporum. directed by Martin of INRA, France and the molecular analysis performed by the Italian team, now shows that truffles need crossing, which means that they act both genders and sexual reproduction of the fungus occurs between strains with different mating types (opposite sex).

The team studied samples from wild strains of black truffle in a natural truffle orchard near Spoleto in central Italy. The study showed that the strains of the opposite sex are not evenly distributed in the areas of potentially productive land.

The team studied the dynamics of strains of truffle in host plants inoculated with truffle spores and grown in a greenhouse, which showed that there is a competition between different strains of truffle to colonize plant roots, even under controlled conditions.

The fruiting season traditionally begins in late fall, but sexual reproduction is thought to occur in spring. The Italian team proved that at the end of the fruiting season of truffles, are in the ground next to host trees, fungal strains of the opposite sex also showed that strains of fungus present in host trees, colonized, act as mother pair in the reproductive process.

These findings represent a major break in understanding the reproductive strategies of the truffle and the dynamics of truffle strains under field conditions and host plants produced artificially to boost production.

“These results are of great practical use to optimize and increase the production of truffles in the fields around the world”. “It is of great interest to artificial truffle plantations promote a balance of strains of both sexual types. Future research will determine whether the distribution of mating types is a factor that really limits the production of truffles under field conditions.

¿Como van las producciones de Trufa negra en Australia?

Segun la Asociacion de Productores de Trufa en Australia (www.trufflegrowers.com.au) , la cosecha de trufa negra en la temporada 2010 (Junio – Septiembre) se estimó en 1,7 Toneladas.  Las cosechas 2010 fueron significativamente mas altas que el año anterior, sin embargo en algunas areas, una cantidad importante de las trufas cosechadas han sido afectadas por problemas de pudrición.  Este problema esta siendo estudiado y se le ha encargado al gobierno un Proyecto de Investigación a traves de RIRDC que es una entidad que financia proyectos de Investigacion e innovacion en el rubro agricola. Los problemas de pudrición encontrados en las cosechas de trufa en ciertas zonas de Australia, podrían deberse a distintos factores, sin embargo lo más probable es por  suelos con problemas de drenaje y aireación

A continuación les muestro una imagen de un suelo trufero en una plantacion en Yarra Valley, Victoria que me toco visitar, y a mi entender no tiene una textura y estructura óptima (Alto nivel de arcilla) pudiendo generar falta de aireación y alta retención de humedad. Por otra parte, otro de los factores que sumado a la capacidad de drenaje estaría afectando es la aplicación de programa de riego equivocados.

En cuanto a la comercializacion, los Precios pagados a los productores en Australia se movieron entre AUS $ 900 a AUS $ 2.000 y el precio promedio de venta fue de AUS $1.400, lo que equivale aprox a a 1.000 Euros por Kilo de trufa negra.

La venta de trufas en el mercado Australiano se estimó en 500 Kg, por otra parte 1.000 Kg fueron exportados a distintos paises; con la diferencia de la- produccion total sin ventas (+- 200 Kg). La comercializacion de trufas es un tema importante para la industria Australiana, ya que por ser un nuevo rubro en el país, ademas de que existen muchos pequeños productores atomizados esto pasa a ser un tema complejo.

La producción estimada para la temporada 2011 en Australia se espera que supere las 3 Toneladas.
