Original Article


This pot experiment was aimed at characterization of agro-physiological responses of potato to water deficit and exogenously application of salicylic acid (SA) and glycine betaine (GB). Four potato cultivars, Spirit, Born, Arinda and Banba, were exposed to two irrigation regimes (30 and 60% depletion of available soil water) and two levels of both SA (0.5 and 1.0 mM) and GB application (1.0 and 2.0 mM) in addition to the control (0.0 mM SA and GB). Activities of ascorbate peroxidase (APX), superoxide dismutase (SOD), total antioxidant capacity (TAC), ion leakage (IL), fluorescence chlorophyll (Fv/Fm), chlorophyll pigments, root dry mass (RDM) and plant dry mass (PDM) were measured. Water deficiency resulted in significant effects on all characteristics. Antioxidant enzymes and IL increased, but the other characteristics decreased significantly with water deficit. Tolerant cultivars (Spirit and Born) revealed higher activity of SOD enzyme, chlorophyll content, PDM and lower IL than non-tolerant cultivars (Arinda and Banba). This investigation has been able to provide evidence that SA and GB affected antioxidant enzymes and increased chlorophyll pigments and PDM. The range of the increases seemed greater when potato cultivars were grown under water deficit circumstances. PDM increased by increasing SA and GB levels. This led to the supposition that injurious effects on potato cultivars due to water deficit could be relieved by SA and GB.

Exogene Anwendung von Salizylsäure und Glycin-Betain als Tools zur Förderung der Biomasse und der Toleranz von Kartoffelsorten


Ziel des Topfversuchs war die Charakterisierung der agrophysiologischen Reaktionen von Kartoffeln auf Wassermangel und auf die exogene Anwendung von Salizylsäure (SA) und Glycin-Betain (GB). Vier Sorten, Spirit, Born, Arinda und Banba, waren 2 Bewässerungssystemen (30- und 60 %ige Reduktion des verfügbaren Bodenwassers) und 2 SA- (0,5 und 1,0 mM) und GB-Anwendungsregimes (1,0 und 2,0 mM) ausgesetzt; eine Kontrolle (0,0 mM SA und GB) diente als Vergleich. Gemessen wurden die Aktivitäten der Ascorbatperoxidase (APX) und der Superoxiddismutase (SOD) sowie die Antioxidationskapazität insgesamt („total antioxidant capacity“, TAC), der Elektrolytverlust („ion leakage“, IL), die Chlorophyllfluoreszenz (Fv/Fm), die Chlorophyllpigmente, die Wurzel- („root dry mass“, RDM) und die Pflanzentrockenmasse („plant dry mass“, PDM). Alle Charakteristika wurden durch Wassermangel signifikant beeinflusst: Die antioxidativen Enzyme und der Elektrolytverlust stiegen; die anderen Charakteristika wurden durch den Wassermangel signifikant reduziert. Tolerante Sorten (Spirit und Born) zeigten eine höhere SOD-Aktivität, einen höheren Chlorophyllgehalt, eine höhere PDM und einen niedrigeren Elektrolytverlust als nichttolerante Sorten (Arinda und Banba). Die Untersuchung konnte zeigen, dass SA und GB antioxidative Enzyme beeinflussten und den Chlorophyllgehalt sowie die PDM erhöhten. Diese Erhöhung schien größer zu sein, wenn Kartoffelsorten unter Wassermangelbedingungen angebaut wurden. Die PDM stieg bei höheren SA- und GB-Konzentrationen an. Dies führte zu der Annahme, dass sich wassermangelbedingte schädigende Effekte durch SA und GB reduzieren lassen könnten.
