Abstract EN
Basella alba is a soft green vegetable, survives in adverse environmental circumstances, for example, very cold temperature although the mechanism and the temperature sensitivity in this species are not clarified.
Pot experiment for cultivation of B.
alba was carried out to examine the effects of low temperature on the synthesis of two enzymes, polyphenol oxidase (PPO) and peroxidase (POD) in leaf of this plant.
They were exposed to 8 C for 24 h, 48 h and 72 h periods and the respective controls were kept in ambient room temperature for the above mentioned time.
Low temperature causes the higher activity of PPO and the threshold level was found after 48 h period when compared to the respective controls.
The activity was higher at 10 mM catechol, substrate for this enzyme, than 100 mM and 200 mM concentration, however, the three doses yielded the gradual increase in activity.
Similar stimulatory effects on peroxidase (POD) activity in leaf were observed whenever the plants were exposed to cold for 24 h, 48 h and 72 h periods and maximal after 48 h period.
Our findings demonstrate that the higher activity of these enzymes in leaf might be an index for the regulatory mechanism of the survival of these species in such adverse environment.
