Description
Die Erfindung betrifft Mittel zur Erhöhung der allge meinen Streßtoleranz von land- und forstwirtschaftlichen Kulturpflanzen, insbesondere gegenüber abiotischen Stressoren.The invention relates to means for increasing the general my stress tolerance of agricultural and forestry Cultivated plants, especially towards abiotic ones Stressors.
Es ist bekannt, daß land- und forstwirtschaftliche Kul turen vielfachen Belastungen ausgesetzt sind.It is known that agricultural and forestry cult structures are exposed to multiple loads.
Durch den Einsatz von Pflanzenschutzmitteln und auch von biologischen Verfahren werden bekanntlich jene Schäden verhindert oder zumindest begrenzt, die biotischen Ur sprungs sind, beispielsweise ein Befall durch Schader reger oder auch der Unkrautwuchs.Through the use of pesticides and also from biological processes are known to cause that damage prevented or at least limited, the biotic primal jump, for example an infestation by malware brisk or weed growth.
Es ist ferner bekannt, daß land- und forstwirtschaft liche Kulturen in ständig zunehmenden Maße auch Be lastungen ausgesetzt sind, die physikalisch-chemischer Natur sind und vor allem durch das Klima und Umweltschad stoffe induziert werden.It is also known that agriculture and forestry cultures to an ever increasing extent exposed to physical and chemical loads Are nature and above all due to the climate and environmental damage substances are induced.
Zu diesen abiotischen Stressoren gegenüber Pflanzen ge hören beispielsweise Belastungen durch Trockenheit, fer ner durch Salz Hitze und Kälte, aber auch durch Schad stoffe in Luft und Wasser. Es ist bekannt, daß beispiels weise organische Stoffe in der Atmosphäre zudem auch photooxydativen Veränderungen unterliegen. Pflanzen sind daher im allgemeinen der gleichzeitigen Belastung durch verschiedene Stressoren ausgesetzt.To these abiotic stressors against plants hear, for example, exposure to drought, fer by salt, heat and cold, but also by damage substances in air and water. It is known that, for example also wise organic substances in the atmosphere subject to photo-oxidative changes. Plants are hence generally the simultaneous exposure to exposed to various stressors.
Es ist zu erwarten, daß diese global festzustellende Be lastung der Pflanzen durch klimatisch bedingte Faktoren selbst in gemäßigten Zonen an Bedeutung gewinnen wird. Der zunehmende CO2-Gehalt der Atmosphäre und die durch den Treibhauseffekt in den letzten Jahren zu beobachten de Erhöhung der Jahresdurchschnittstemperaturen bringen schon heute manche Probleme; physiologische Trockenheit kann an Kulturpflanzen bekanntlich erhebliche Ertrags depressionen verursachen.It is to be expected that this global burden on plants due to climatic factors will become more important, even in temperate zones. The increasing CO 2 content in the atmosphere and the increase in average annual temperatures that have been observed in recent years due to the greenhouse effect are already causing some problems today; As is well known, physiological drought can cause significant crop depression in crops.
Es hat nicht an Versuchen gefehlt, beispielsweise die Wasserausnutzung der Pflanzen durch Applikation transpi rationshemmender Substanzen zu verbessern.There was no lack of attempts, for example the Use of water in plants by applying transpi to improve ration-inhibiting substances.
Diese bewirken entweder eine zeitweilige Stomataapertur verkleinerung (DE-OS 17 67 829, DD 217 975, DD-PS 103 124, DD-PS 85 224) oder die Ausbildung von für Wasserdampf schwerdurchlässigen Molekularfilmen auf den Blättern (DE-OS 17 67 100, DE-OS 17 67 427, US 2333 887, US 2 923 095).These either cause a temporary stoma aperture downsizing (DE-OS 17 67 829, DD 217 975, DD-PS 103 124, DD-PS 85 224) or the training of for water vapor impermeable molecular films on the leaves (DE-OS 17 67 100, DE-OS 17 67 427, US 2333 887, US 2 923 095).
In der DD-PS 151 104 wird vorgeschlagen, Ethanolamin allein oder in Kombination mit Azetylsalizylsäure und gegebenen falls Paraformaldehyd als Mittel zur Erhöhung des Wasser aneignungsvermögens, insbesondere von Getreide und Zucker rüben, einzusetzen.DD-PS 151 104 proposes ethanolamine alone or in combination with acetylsalicylic acid and given if paraformaldehyde as a means of increasing water appropriateness, especially of cereals and sugar beets.
Aus der DD 255 874 A1 ist ferner bekannt, N-(2-Hydroxy ethyl)piperazin als Mittel zur Erhöhung der Salztoleranz von Kulturpflanzen, vorzugsweise von Getreide auf NaCl-ver salzten Böden zu verwenden.DD 255 874 A1 also discloses N- (2-hydroxy ethyl) piperazine as a means of increasing salt tolerance of crops, preferably cereals on NaCl ver to use salted soils.
Mit dem Einsatz von Phytohormonen schien sich ein neuer Lösungsweg abzuzeichnen. Diese Substanzen und auch synthe tische Wirkungsanaloga werden aber von den Pflanzen oft schlecht aufgenommen, in der Pflanze zu schnell metaboli siert und sind zudem in der Herstellung sehr kostenauf wendig.With the use of phytohormones appeared a new one Sign off the solution. These substances and also synthe However, plants often produce functional analogues poorly absorbed, metaboli too quickly in the plant and are also very expensive to manufacture agile.
Aus der Fachliteratur ist ersichtlich, daß Mittel zur Er höhung der Toleranz gegenüber einzelnen Stressoren be kannt sind. Ein Weg zur Verbesserung der allgemeinen Streß toleranz, insbesondere gegenüber abiotischen Stressoren, wurde aber nicht gefunden.From the specialist literature it can be seen that means for Er increase in tolerance to individual stressors are known. A way to improve general stress tolerance, especially towards abiotic stressors, was not found.
Es bestand somit die Aufgabe, Mittel zur Erhöhung der Streßtoleranz land- und forstwirtschaftlicher Kultur pflanzen, insbesondere gegenüber abiotischen Stressoren, zu entwickeln, die kostengünstig herstellbar und vor allem toxikologisch unbedenklich sind.There was therefore the task of increasing funds Stress tolerance of agricultural and forestry culture plants, especially against abiotic stressors, to develop the inexpensive to manufacture and before are all toxicologically safe.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Mittel neben üblichen Hilfs- und Trägerstoffen als Wirkstoff eine Kombination aus Cholinchlorid (I) und N-(2-Hydroxyethyl)-piperazin (II) enthalten, wobei das N-(2-Hydroxyethyl)-piperazin auch in Form seiner Salze mit Mineralsäuren vorliegen kann und das Masse verhältnis der Komponenten I : II = 1 : 0,05 bis 0,5 beträgt.This object is achieved in that the means in addition to the usual auxiliaries and carriers as Active ingredient a combination of choline chloride (I) and Contain N- (2-hydroxyethyl) piperazine (II), where the N- (2-hydroxyethyl) piperazine also in the form of its Salts with mineral acids can be present and the mass ratio of components I: II = 1: 0.05 to 0.5 is.
Es wurde überraschenderweise gefunden, daß die Anwendung der erfindungsgemäßen Mittel - offenbar durch eine wirk stoffinduzierte Vitalitätssteigerung - zu einer signi fikanten Erhöhung der Streßtoleranz land- und forst wirtschaftlicher Kulturpflanzen führt. Die experimen tellen Ergebnisse belegen - bezogen auf die Anwendung der Einzelsubstanzen - einen echten Synergismus.It has surprisingly been found that the application of the agent according to the invention - apparently by an effective substance-induced increase in vitality - to a significant noticeable increase in the stress tolerance in rural and forest areas of economic crops. The experiments prove results - based on the application of the individual substances - a real synergism.
Erste Versuche zeigen, daß durch die protektive Anwendung der erfindungsgemäßen Mittel selbst in Jahren ohne Trockenstreß eine Qualitätssicherung des Erntegutes er reicht wird und keine Ertragsminderungen auftreten; viel mehr wird die Resistenz der Pflanzen verbessert und der Befall durch Schaderreger geringer.First attempts show that through the protective application of the agent according to the invention even in years without Dry stress a quality assurance of the crop is sufficient and there are no reductions in yield; a lot the resistance of the plants is improved and the Infestation by pests less.
Von Vorteil ist auch, daß die Wirkstoffkombination in toxikologischer Hinsicht unbedenklich ist.It is also advantageous that the active ingredient combination in is toxicologically harmless.
Die Einzelwirkstoffe sind Handelsprodukte; ihre Her stellung ist aus der Literatur bekannt.The individual active ingredients are commercial products; her fro position is known from the literature.
Durch die Ausführungsbeispiels soll die vorteilhafte Wirkung der Anwendung der erfindungsgemäßen Mittel bei landwirtschaftlichen Großkulturen näher erläutert werden.The exemplary embodiment is intended to be advantageous Effect of using the agents according to the invention major agricultural crops are explained in more detail.
Der Einfluß der erfindungsgemäßen Mittel wurde in einem Mitscherlich-Gefäßversuch mit Sommergerste "Salome" und Winterweizen "Mikon" ermittelt. Die Pflanzenanzucht er folgte nach Standardvorschriften für Gefäßversuche [7 kg Quarzsand/Boden-Gemisch im Verhältnis 2 : 1; Befeuchten des Gefäßsubstrates auf 50% der nutzbaren Wasserkapazi tät und kontrollierte Wasserversorgung durch tägliches Gießen/nach Gewicht; Düngung: 0,54 g P, 1,6 g N (1/2 da von als Kopfdüngung), 1,48 g K (1/2 davon als Kopfdüngung), 0,33 g Mg, 1 ml 10% FeCl3-Lösung und Mikronährstoffe].The influence of the agents according to the invention was determined in a Mitscherlich vessel test with summer barley "Salome" and winter wheat "Mikon". Plant cultivation was carried out according to standard regulations for vascular tests [7 kg quartz sand / soil mixture in a ratio of 2: 1; Moistening the vascular substrate to 50% of the usable water capacity and controlled water supply through daily watering / by weight; Fertilization: 0.54 g P, 1.6 g N (1/2 da from as top fertilizer), 1.48 g K (1/2 from top as fertilizer), 0.33 g Mg, 1 ml 10% FeCl 3 solution and micronutrients].
Die erfindungsgemäßen Mittel wurden zu DC 31/32 über
Sproßapplikation auf den trockenen Pflanzenbestand ge
sprüht. Zur Trockenstreßinduktion sind 3 Streßperioden
von je 4 Tagen Dauer im Zeitraum zwischen Ährenschieben
bis Ende Kornfüllung durch Absenken der Substratfeuchte
auf 30% der nutzbaren Wasserkapazität eingelegt worden.
Neben dem Kornertrag wurde der Streßtoleranzindex (SI)
ermittelt. Der SI-Wert errechnet sich wie folgt:
The agents according to the invention were sprayed onto DC 31/32 via shoot application onto the dry plant stand. For the induction of dry stress, 3 stress periods of 4 days each have been inserted in the period between earing and filling the grain by lowering the substrate moisture to 30% of the usable water capacity. In addition to the grain yield, the stress tolerance index (SI) was determined. The SI value is calculated as follows:
Die Ergebnisse sind in den Tabellen I und II zusammen gefaßt. The results are summarized in Tables I and II composed.
