Sažetak
An investigation on the growth and cropping of plum trees, which were cultivated on heavy soil, has been conducted for seven years after planting (1997-2003). The experiment included plum cultivars ‘ Felsina’ , ‘ Elena’ and ‘ Top’ grafted on rootstock GF 655/2, and planted at three densities (3.8 x 1.8, 3.8 x 2.2 and 3.8 x 2.6 m). After 7 seasons, growth of the trees, as indicated by trunk cross-sectional area (TCSA) of ‘ Felsina’ , were the least vigorous while ‘ Top’ were the most vigorous. ‘ Felsina’ did not yield as expected and was very sensitive to plum pox virus. ‘ Top’ and ‘ Elena’ were precocious and produced high yields. ‘ Top’ showed slight sensitivity, whereas ‘ Elena’ was highly tolerant to plum pox virus. In our growing conditions, among cultivars in trial, ‘ Elena’ is the most promising for modern, intensive plum growing because it was precocious, productive and gave fruits of good quality.
