Physiological responses of Tillandsia albida (Bromeliaceae) to long-term foliar metal application

Popis výsledku v původním jazyce

The impact of 2 month foliar application of cadmium, nickel and their combination (10 uM) on Tillandsia albida was studied. Cadmium caused damage of tissue but assimilation pigments were depressed in Cd + Ni variant only. Stress-related parameters (ROS and peroxidase activities) were elevated by Cd and Cd + Ni while MDA content remained unaffected. Free amino acids accumulated the most in Ni alone but soluble proteins were not influenced. Among phenolic acids, mainly vanillin contributed to increase oftheir sum in all variants while soluble phenols even decreased in Cd + Ni and flavonols slightly increased in Cd variants. Phenolic enzymes showed negligible responses to almost all treatments. Mineral nutrients (K, Ca, Na, Mg, Fe, and Zn) were not affected by metal application but N content increased. Total Cd or Ni amounts reached over 400 ug g 1 DW and were not affected if metal alone and combined treatment is compared while absorbed content differed (ca. 50% of total Cd was absorbed
