Investigation of different disinfection treatments on the explants of Cranberry (Vaccinium arctostaphylos L.)

Cranberry (V. arctostaphylos L.) which locally named Shihard is belonging to Ericaceae family. The fruit is spherical and spicy and it has high commercial value because of the presence of the anthocyanin, flavonoids, anticancer and antimicrobial compounds. This research was conducted to investigate the disinfection methods of Cranberry in three different tests. The first experiment was to evaluate the disinfection of the explant of five different ecotypes including; Horan, Soha, Khalkhal, Lisar and Paresar. The second experiment examines the effect of changing the pH of the disinfectant solution and the third experiment investigated the effects of tetracycline and silver nitrate on disinfection of cranberry explants. In the first experiment, the Lisar ecotype was considered as the best ecotype for healthy samples, in the second experiment, pH = 9 was the best, and in the third experiment, silver nitrate had the highest percentage of healthy sputum samples. In general, many factors effects on disinfection of explants. The results of these experiments showed that type of ecotype, disinfectant materials and pH effects on disinfection of cranberry explants.
