Procesy wzrostu i rozwoju roślin są regulowane przez hormony roślinne jak również przez czynniki środowiskowe np. temperaturę. Celem badań było wyznaczenie temperaturowej zależności aktywności oddychania komórek segmentów koleoptyli Zea mays L., indukowanego przez IAA i 4-Cl-IAA. Badania przeprowadzono na 10 mm, etiolowanych segmentach koleoptyli kukurydzy z których usunięto pierwszy liść. Pomiary zawartości tlenu w środowisku segmentów koleoptyli kukurydzy przy braku i w obecności wybranych substancji wzrostowych przeprowadzono przy użyciu elektrody tlenowej oraz tlenomierza. Wykazano, że pobieranie tlenu przez segmenty koleoptyli kukurydzy jest zależne od temperatury.
Plants continuously encounter different types of environmental stresses, among which extreme temperatures are very critical for their growth and development. On the other hand, these processes are also precisely regulated by plant growth substances among which indole-3-acetic acid (IAA) plays a key role. The main objective of the present study was a comparison of the effects of indole-3-acetic acid (IAA) and 4-chloroindole-3-acetic acid (4-Cl-IAA) on oxygen uptake in maize coleoptile segments incubated at a wide range of temperatures (10 - 45°C). The experiments were performed with 10 mm coleoptile segments cut from 4-day old etiolated seedlings. Changes in oxygen uptake by maize coleoptile segments, incubated with and without of auxins, were measured using a oxygen electrode. It was found that the uptake of oxygen in maize coleoptile segments was temperature-dependent.
