Abstract
Description
Die Erfindung betrifft den Anwendungsmodus der Wachstumsregulatoren zur exogenen Steuerung der Assimilatverteilung unter Berücksichtigung der hormonellen Regulation assimilatorischer und dissimilatorischer Prozesse, die ihrerseits durch Umweltreize (Licht, Temperatur, Wasser- und Nährstoffversorgung), aber auch durch exogene Wirkstoffapplikation beeinflußbar sind. Das Verfahren hat zum Ziel, die Erträge generativer Speicherorgane in der pflanzlichen Produktion auf einem hohen Ertragsniveau zu sichern. The invention relates to the mode of application of the growth regulators for exogenous control of the assimilate distribution taking into account hormonal regulation assimilatory and dissimilatory processes that in turn through environmental stimuli (light, temperature, water and nutrient supply), but also through exogenous Drug application can be influenced. The procedure aims to increase the yield of generative storage organs in crop production at a high yield level to secure.
Seit Anfang der sechziger Jahre sind erste WR (Wachstumsregulatoren) vor allem zur Halmverkürzung bei Getreide, aber auch zur Vermeidung des Lagerns der Pflanzenbestände anderer Kulturen in der praktischen Anwendung.The first WR have been in use since the early 1960s (Growth regulators) especially to shorten the stalks Cereals, but also to avoid storing the Plant stands of other crops in practical Application.
In größerem Umfang kommen diese WR weiterhin im Baumwollanbau und abreiferegulierende Verbindungen im Zuckerrohranbau sowie verschiedenen Sonderkulturen oder als Anti- Transpiranz in der pflanzlichen Produktion zum Einsatz. Neben dem CCC (Chlorcholinchlorid) wurden bereits zahlreiche Substanzen mit ähnlicher Wirkungsweise gefunden. Moderne hochwirksame Verbindungen kommen vor allem aus der Gruppe der Triazole mit zum Teil auch fungizider Wirkung. Ihre Wirkungsweise ist dadurch gekennzeichnet, daß sie entweder direkt die Aktivität der Gibberelline und Auxine senken oder über den indirekten Weg die Aktivität der entsprechenden Antagonisten (Abscissine, Ethylen und z. T. Kinetine) erhöhen.To a large extent, these WR continue to come from cotton cultivation and ripening regulating compounds in sugar cane cultivation as well as various special cultures or as anti Perspiration used in plant production. In addition to the CCC (chlorcholine chloride) have already been numerous substances with a similar mode of action found. There are modern, highly effective connections all from the group of triazoles with some fungicidal activity. This is how it works characterized that they are either directly the activity of Gibberelline and Auxine lower or over the indirect Away the activity of the corresponding antagonists (Abscissine, ethylene and partly Kinetine) increase.
Beim Anbau intensiver, genetisch kurzer Getreidesorten oder einer entsprechend hohen WR-Aufwandmenge kommt es jedoch bei unvorhersehbaren suboptimalen Wachstumsbedingungen zu erheblichen Ertragseinbußen aufgrund einer mangelnden Ertragssicherheit.When growing intensive, genetically short cereals or a correspondingly high WR application rate however with unpredictable suboptimal growth conditions to significant earnings losses due to a lack of income security.
Der Erfindung liegt die Aufgabe zugrunde, in der pflanzlichen Produktion neben einer Ertragserhöhung auch eine Steigerung der Ertragssicherheit zu erreichen.The invention is based, in which crop production in addition to an increase in yield to achieve an increase in earnings security.
Die Aufgabe wird mit dem kennzeichnenden Merkmal des Anspruches 1 gelöst.The task is characterized by the characteristic of Claim 1 solved.
In Untersuchungen (siehe Ergebnisse im Anhang Tab. 1) zur Bedeutung unterschiedlicher Frühjahrswitterungen auf die Ertragsstruktur von Sommerweizen konnte festgestellt werden, daß besonders bei warmen Frühjahrstemperaturen die Assimilateinlagerung in die Ähre bereits durch eine einmalige WR-Gabe verbessert wurde, jedoch bei entsprechend kühler Frühjahrswitterung erhebliche Ertragseinbußen auftraten.In studies (see results in Appendix 1) for Importance of different spring weather conditions on the Yield structure of summer wheat was determined be that especially in warm spring temperatures Assimilate storage in the ear already through a one-time WR dose was improved, however at correspondingly cool spring weather considerable Yield losses occurred.
In Untersuchungen mit radioaktivem 14CO2 begasten Pflanzen (Tab. 2 u. 3) konnte des weiteren ermittelt werden, daß die WR-behandelten Pflanzen aufgrund der geringeren Pflanzenmasse absolut weniger CO2 assimilieren. Durch eine erhöhte Assimilatveratmung (Tab. 7), welche u. a. Energie für die Assimilateinlagerung in die generativen Sinks liefert, konnte bei gleichzeitig verzögerter Gesamtpflanzenentwicklung (Tab. 4 u. 5) der Assimilattransport in die Ähre (Tab. 5 u. 6.) deutlich gesteigert werden. Inwieweit diese, auch als Attraktionsatmung bezeichnete Dissimilation, einen Mehrertrag induziert, hängt jedoch von ihrer Effizienz sowie ihrem Verhältnis zur Assimilation, bzw. zur Brutto-Assimilatanlieferung in die generativen Sinks ab.In studies with radioactive 14 CO 2 fumigated plants (Tables 2 and 3) it was also possible to determine that the WR-treated plants assimilate less CO 2 due to the lower plant mass. Due to an increased assimilate respiration (Tab. 7), which among other things provides energy for the assimilate storage in the generative sinks, the assimilate transport into the ear (Tab. 5 and 6.) was clearly evident while the overall plant development was delayed (Tab. 4 and 5) be increased. The extent to which this dissimilation, also known as attraction breathing, induces an additional yield depends on its efficiency and its relationship to assimilation or to the gross assimilate delivery into the generative sinks.
Die hormonelle Stimulation dieser Attraktionsatmung ist genetisch in einem gewissen Rahmen abgesteckt, unterliegt jedoch erheblichen, unterschiedlichen Einflüssen einzelner Versuchsjahre bezüglich Temperatur, Wasser- und Nährstoffversorgung. Daher kann ihre Optimierung zur Ertragssicherung, bzw. zur Ertragssteigerung nur durch eine entsprechend angepasste WR-Gabe erfolgen.The hormonal stimulation of this attraction breathing is genetically staked out to a certain extent, is subject to however considerable, different influences of individual Trial years with regard to temperature, water and nutrient supply. Therefore, their optimization to secure earnings, or to increase the yield only by one appropriately adapted WR gift.
Bisher wurde die WR-Applikation nur zur Halmverkürzung in hoch dosierter Form als einmalige oder geteilte Gabe ohne Berücksichtigung der dadurch verursachten assimilatorischen und dissimilatorischen Veränderungen eingesetzt.So far, the WR application has only been used to shorten the stalk in high doses as a single or divided dose without taking into account the resulting assimilatory and dissimilatory changes used.
Der entscheidende Vorteil der WR-Applikation gemäß Anspruch 1 liegt darin, daß der Pflanzenbestand noch während der Vegetation unter Berücksichtigung der allgemeinen Wachstumsbedingungen auf die jeweils für die Ertragsbildung optimale Stimulation assimilatorischer und dissimilatorischer Prozesse reguliert wird. The decisive advantage of the WR application according to Claim 1 is that the plant population is still during the vegetation taking into account the general growth conditions on each for the Yield formation optimal stimulation assimilatory and dissimilatory processes is regulated.
