THE INFLUENCE OF SHURBS CUTTING METHOD ON YIELDING AND QUALITY OF THE GOJI BERRIES (LYCIUM BARBARUM L.)
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2016, Vol 40, Issue 330
Abstract
In the experiment were compared: the growth of shrubs, yielding, the physical parameters of fruits and their chemical composition depending on the method of cutting bushes – the amount of main shoots. Research material consisted of goji berries grown in Department of Horticulture Research Station of the West Pomeranian University of Technology in Szczecin. Goji berries (Lycium barbarum L.) are characterized by high potential of health promoting properties and nutritious. They have been extremely important part of traditional Chinese medicine for ages. They are used there as a very important part of a healthy diet, due to the appearance of the complex polysaccharide valuable LBP (Lycium Barbarum Polysaccharides). Cutting of shoots stimulated growth of shrubs. Bushes cut into 3 shoots grew with larger number of shorter basal shoots, while the one-year shoots were the longest. The leaves of the cut bush were darker (L* = 39.8 and 41.2) and had a higher green index (42.1 and 44.8), in comparison to uncut bushes (L* = 37.3, SPAD = 43.5). It was also found that there is a significant correlation between the green index and the value of the parameter a* (r* = 0.92). Cutting of shrubs, especially into 3 shoots, reduced yielding however influenced increasing the size of the fruit.
