Advantage of in vitro walnut trees as opposed to grafted trees

The absence of a graft point eliminates a point of stress for the tree. This, in turn, improves the vigor and productivity of in vitro walnut trees.

Advantages of self-rooted walnut trees for wood production

These are clones selected because of their high productivity. There is also no grafting point that may depreciate wood.

Advantages of the UCB1 pistachio rootstock

These are rootstocks with a lot of vigor that are resistant to Verticillium, with a successful graft percentage of nearly 100% in the first year and with fast production (beginning the fourth year).

Our Products

Walnut-bearing trees

Our country is one of the world's largest importers of nuts; annual production is not nearly enough to supply current demand. MERISTEC proposes this crop as an alternative that has higher profitability than most other crops.

Walnut trees for timber

Walnut tree wood is one of the most esteemed woods on both the national and international markets. It has densities of 600 to 750 kg/m3, medium-grade hardness, fine grain, and straight fibers. It is homogeneous, very elastic, and heavy. It resists weather and fungi well.

Pistachio trees

Meristec offers its customers the best pistachio tree clonal rootstocks on the market: the UCB1 clonal rootstock sold in California. It is resistant to Verticillium dahliae and is also tolerant to salinity and cold winters.

Biotechnology at your service

Biotechnology aims to use living organisms or biological systems to create or modify products. It also aims to improve plants, animals, and microorganisms to be able to use them in certain processes. Examples of the use of biotechnology are the production of bread or beer (thanks to the fermentation of flour or barley), or the industrial production of insulin, thanks to the use of genetically modified bacteria.

Micropropagation, or in vitro growing, is a process to multiply plants in mass through the use of plant biotechnology techniques. It consists of rooting micro-shoots of the clone or variety to propagate under extremely optimized and controlled laboratory conditions. In this way, a yield is achieved that would be impossible to obtain through conventional techniques (in the greenhouse or the field).

The different species present different degrees of difficulty in terms of their micropropagation. Not always can the most interesting species from an economic standpoint be propagated in vitro with ease, which is why, in order to produce the species that interest our clients commercially, it is necessary to undertake major research efforts.

The goal of MERISTEC is for our customers to be able to take advantage of products that provide them with high levels of profitability.
