Comparative palynobiometric study of seedless vine cultivars and hybrid forms (Vitis vinifera L.)
Venelin Roychev
Abstract: A palynobiometric study of seedless vine cultivars and hybrid forms has been carried out. It has been established that statistically proven differences exist in the dimensions of the most important elements of the pollen aperture complex in the researched seedless cultivars and hybrid vine forms. The statistical groups formed according to the individual indicators are specific for each cultivar and fully reflect the observed palynobiometric polymorphism. The variability of polar axis length is influenced by all studied indicators of the ultrasculptural ornamentation of the pollen exine in the two conditional groups of cultivars. It depends to the greatest extent on the variation of the parameters of the equatorial axis and colp length.
Keywords: factor analysis; multifactorial dispersion analysis; palynobiometric characteristics; pollen; seedless vine cultivars
