To assess the effect of cold stress on banana, twenty-eight global and local cultivated clones were used for morphological and <br>physio-biochemical evaluation. Methods: The banana clones were produced from shoot tips under in vitro conditions. When the plants were <br>20-25 cm in height and 5-6 leaves, they were transferred to climate-controlled rooms. The temperature of the testing room was gradually <br>decreased every three days (from 28ºC day/22ºC night to 4ºC day/-1ºC night). After the seedlings remained at these temperatures, the <br>temperature of the room was increased every three days (from 4ºC day/-1ºC night to 28ºC day/22ºC). When the treatment room reached <br>control room conditions (28ºC day/22ºC night), measurements and analyses were started. Results: Low-temperature stress decreased <br>pseudostem length, pseudostem diameter, leaf area, and leaf number of banana clones. The malondialdehyde contents (MDA) were <br>increased compared with control; the chlorophyll content and fluorescence decreased significantly. When temperatures return to normal <br>conditions (28ºC day/22ºC night), only eight banana clones managed to survive and twenty banana clones irreversibly died. After a <br>gradual increase in temperatures, plants have continued to live and form new leaves. Conclusion: At the end of study, it was understood <br>that the low temperatures applied would be sufficient to determine the low-temperature tolerance in banana clones and could work at <br>lower temperatures</p> ER -
