Little about the origin of dentryllion subjects. Divided into seedlings and clones. Ie those that are multiplied by native seed and what their multiplication is done by using small pieces of stems, roots or leaves or by the use of known layering. Yielding said method plants copies of the parent (the well known cloning). Historically we mention the following: Avocados with subjects (spur with inoculum) grown from seeds have high genetic variability. This attribute specifies that every tree has a different behavior. Until the eighties, nurseries only growing plants with imported seed of like Lula, Mexicola and Topa-topa.
Underlying call the tree that is placed in the bowl. It consists of the radical of the body or part of a seedling (wild) or clonal subject e.g. by grafting onto which is grafted our variety. Cambium is the cell layer between bark and wood multiplied produces inner timber and outer shell. Vaccination produce our fruit trees of preference depending on the tree size, karpoparagogis, disease resistance, the replacement of new varieties etc.
Differences seedlings of clonal avocado historical information
Differences seedlings of clonal avocado. Later researchers realized that to get low in height and homogeneous trees in terms of size and production and also resistant to fungi trees, they had to use Mr. lonika subjects (from slips). Selected for this purpose, since 1983, the clonal plant roots of Duke-7 and G-6 (and Mexican race Drymifolia). Because they are resistant to Phytophthora cinnamomi and extremely productive. These two subjects were selected by Dr. George A. Zentmyer, from the University of California. Control of avocado varieties held in an area of 11 hectares plantation to determine their effectiveness.
Spur (grafting) avocados information. vaccination avocado
Namely avocados are ideal months for vaccination is September and October with enofthalmikoi vaccinations and sleeping eye “T” (Beware the variety Hass presents ofthalmoptosi) . The ideal tools you need for a vaccination knife with a curved tip or straight blade depending on type of vaccination that you choose, an ointment (mastic) vaccination for the prevention of tree wounds, plastic strip (rubber) or adhesive plastic (Tellos electrician), plastic twine and finally a transparent plastic film of polyethylene.
Years ago, when a new plantation Avocado arrived in America, vaccinations were not given importance to the subject. Philosophy to emerge Ana nursery avocado with vigor and health. Time Over, unfortunately, they appeared on some plantations soil diseases such as Phytophthora cinnamomi or Rosellinia necatrix. Symptom root rot produced by fungi and result in tree death. Remember sapiloriziasma ours? All this made the researchers to rethink the importance of the subject.
Main factors for a good vaccination
The subject is primarily responsible for the absorption of nutrients that will determine both the size of the plant, such as the production and environmental adaptability is on, ie, soil, water and other environmental factors. This will determine the morphology of fruits and trees and their longevity. Another important element to be considered should be the relationship of the subject with variety so that ships can transport them safely and juice can be moved fluently without herpes or fungi in both directions.
Order Planting: 6 x 6 m. interim accommodation for 15/17 years and certainly 8,60 x 8,60 m.
All varieties and subjects that we offer to our nursery have been rigorously tested in our land. We aim to provide accurate advice for you to choose in each case the varieties and the subjects that are best suited to the specific characteristics of the seat of your country. Strictly control the production process, which allows us to guarantee the authenticity of the variety of plants and sell them arrive to you in the best plant health conditions and provide the appropriate certification .
