"To define a plant" means to establish its systematic accessory (look, a sort, family), to learn the scientific name, to receive data on its biology and ecology. You will be able to make by means of determinant of plants.
It is required to you
- Determinant of plants.
Instruction
1. definitionplantsIt is possible to carry out both on live by a copy, and on dried. However sometimes on a herbarium it is more convenient to do it. For example, to define a kind of a sedge, it is necessary to know, it has a long or short rhizome. Useful will be data on what soil and at what lighting the plant grew. You should not carry out definition as regards a plant, you hardly receive result.
2. For definition of plants you need the atlas determinant. It consists of tables. Each table , in turn, consists of consecutive steps which are designated by serial numbers. Each step consists of a teza and an antithesis. Teza has the same serial number, as a step, and an antithesis — a minus sign.
3. Teza and an antithesis contain opposite signs of plants. Also the teza and an antithesis contain number of a step to which it is necessary to pass if the described sign coincided with sign of the copy determined by you. Thus, you constantly have to choose the signs observed at a sample and, after all, will reach a teza or an antithesis which contains not signs, but the name of a plant.
4. If you carry out definition not in field conditions, and on a herbarium, and you have near at hand an Internet, you can use electronic determinant of plants (for example, planetariumy). Its work is constructed by the principle of paper determinant. The user needs to specify signs, characteristic of a plant, and the computer program itself will count possible options.
5. If the description of a plant in the last teza or an antithesis coincides with the copy found to you, so all of you made truly. In case the result does not suit you, carry out definition from the very beginning. If the mistake repeated, perhaps, you found a look which is not in determinant.
