Interaction between vegetative and reproductive manifestations in raspberry candidate cultivar Magdalena
Stanislava Atanasova, Maria Georgieva, Diyan Georgiev
Abstract: The interconnections between the vegetative and reproductive manifestations of the candidate raspberry cultivar ‘Magdalena’ were monitored. The scientific experiment was conducted in a collection plantation of the Research Institute of Mountain Stockbreeding and Agriculture in Troyan in the period of (2018-2020). The field experiment is based at intra-row spacings between plants (0.50 m and 0.30 m) and inter-row spacings of 3.00 m. The indicators, such as average number of shoots, average height and average thickness of shoots, average fruit weight (g), and average yield (g) per one linear meter of the intra-row area. The largest number of shoots (35.50) for the candidate cultivar ‘Magdalena’ was found in the planting spacing of 0.30 m variant, while the highest height of shoots (183.15) was registered at the larger (0.50 m) planting distance. The average thickness of the shoots varied from 6.31 mm to 7.52 mm. Significantly higher yields were found for ‘Magdalena’ candidate cultivar at the shorter planting distance in the first two experimental years, and this regularity changed in 2020, when the highest average yield from the tested period was reported (2543.67 g/m), but at 0.50 m planting distance. The highest average fruit weight of 3.30 g was reported from the greater planting distance in 2018.
