Abstract

Our paper presents aspects regarding the influence of culture vessels upon multiplication rate in the highbush blueberry ( Vaccinium corymbosum ) cultivar `Blue Crop`. Modified Woody Plant Medium (WPM) with 5 mg/l 2-Isopentenyladenine (2-Ip) and 20 mg/l ascorbic acid was used as culture medium. The following types of culture vessels were tested: Magenta GA7, 720 ml jars with metal caps vented with sponge filters, 720 ml jars with polycarbonate caps without venting, 720 ml jars with vented polycarbonate caps equipped with filters made of water-resistant bandaids, 320 ml jam jars with polycarbonate caps without venting and Eco 2 Box vessels with vented caps. The best growth and highest multiplication rates were obtained in the 720 ml jars with metal caps vented with sponge filters and the shoots were vigorous, with intense green color.
