Wpływ podłoża na ukorzenianie się sadzonek zielnych i zdrewniałych borówki wysokiej odmiany Bluecrop
MetadataShow full item record
The research was conducted at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin to study the effectiveness of the rooting ability of softwood cutting and hardwood cutting of the highbush blueberry in substrates containing peat, perlite and sand. The percentage of cutting taking root as well as the number and length of roots and the chlorophyll content index were determined. It was found that the reproduction of the blueberry plants of the Bluecrop cultivar was more effective if hardwood cutting were used (64%). Peat perlite and the mixture of the two were the best substrates to cause hardwood cutting and softwood cutting to take root. They had the highest percentage of plants taking root (from 55% to 83%) and the largest number of roots (from 7 to 14). The longest roots were formed in plants grown in substrates prepared from peat and perlite (106 mm) and also in peat alone (110 mm), especially softwood cutting (132–141 mm), which grew roots almost twice as long as those in hardwood cutting. Moreover, the chlorophyll content index (SPAD) was also higher (approx. 50).
