DE2341652A1 - Eliminating or reducing bacteria from pelargonium plants - by change of temp. and-or oxygen deprivation - Google Patents

Abstract

Bacteria are elinated and/or reduced in culturing. Pelargonium plants by heating or cooling the plants, or parts of them, beyond the temp. limits at which the bacteria are killed or reduced, without the plants losing their visibility. Pref. the plants, or a part of them, are stored in a room or container from which the O2 is withdrawn until the bacteria are killed or reduced; this can be combined with the temp. change. The process and appts. may be applied to other decorative plants also. No further details of conditions ar given.

Description Process, device for the destruction and / or reduction of bacteria on pelargonium plants, or parts thereof, or in pelargonium plants, or in parts thereof, with the purpose of maintaining the viability of the plant or parts thereof. that the bacteria live in a certain temperature range and need oxygen, or one of both ». If the plant or the plant part is attacked by the bacterium, there is a risk that the bacterium will multiply quickly and thereby destroy the culture. The economic pressure to optimally utilize the means of production makes the culture more susceptible to bacterial infestation. The risk for the plant or parts of it to become infected by the bacterium exists if the necessary quantities of temperature, oxygen and humidity are present. This then leads to the bacterium appearing to multiply, and this already leads to considerable losses in the culture and its offspring. Attempts are therefore made to produce or multiply plants or parts thereof that are free from bacteria; or limit the bacteria in numbers so low that no harm occurs. For this purpose are used today: 1. Chemical industry products. 2. the meristem culture 3. the influencing of plant growth not according to optimal criteria, but according to the criteria counteract the spread of the bacterium. At the moment there are no known chemical agents in Germany that are effective, economical and environmentally friendly are. The meristem culture is too complex. To prevent the bacterium from growing too quickly, it can It may be necessary to keep the plant or part of it in its optimal growth. But this means that the Resources not optimally used. All of this is prevented by the protection claims described below:
Claim ii Method, device for the destruction and / or reduction of the bacteria on / in the pelargonium plant or parts of it, while maintaining the viability of the pelargonium plant or parts thereof, as well as their offspring; optionally or jointly by the methods described below, Devices. Method, device according to claim It To heat the pelargonium plant or part of it or to cool beyond the temperature limit in which the The bacterium dies or is reduced without the plant or part of it losing its viability. - 2 - 509809/0569 1. The method, device according to claim I: The storage of the pelargonium plant or part of it in a border or container from which the oxygen is withdrawn until the bacterium is killed or reduced, without the plant or part of it losing its viability. 2. Method, device according to claim I: Method, device can optionally, or together can be applied. 3. The method, device according to claim I: The method and device can also be used with other ornamental plants. 4. The method, device according to claim I: The palargonia plants or parts thereof treated according to the method, device according to claim I, as well as their offspring, can be specially marked. 509809/0569 Claim \ I ι \ Method, device for destruction and / or reduction of the bacterium on / in the pelargonium plant or parts thereof, with the preservation of the pelargonium plant or parts thereof, as well as their offspring, optionally or jointly by the methods and devices described below. To heat or cool the plant or part of it beyond the temperature limit in which the bacterium dies or is reduced without affecting the plant or any part of it Lose viability. 1. The method, device according to claim I: Keeping the plant or part of it in a room or container that has been deprived of oxygen until Kills or reduces the bacterium without the plant or any part of it losing its viability. 2. The method, device according to claim II The method and device can be used optionally or together. 3. The method, device according to claim I: The method and device can also be used with other ornamental plants. 4. The method, device according to claim I: The plants or parts thereof treated according to the method, device according to claim I, as well as their offspring, can particularly be marked. 509809 / Π56
