Effect of Various Development Periods on Accumulation of Some Mineral Elements on the Leaves of Strawberry Cultivars (Fragaria X ananassa Dutch. L)

Abstract

An experiment has been set up with Tudla, Muir, Douglas,
Rupella, Moraline, Evita, Aiko, Northeastern, Tioga, Elvira and
Delmarvel cultivars for mineral accumulations of nitrogen,
phosphorus, potassium, calcium, magnesium, manganese, zinc,
copper, iron and boron on plants' leaves were analyzed in three
different periods which are fruit formation (May 26th), stolon
formation (July 13th) and beginning of resting period (September
27th). It was determined that generally mineral elements accumulation
change in relation to development periods. In addition, the
periodic change in nitrogen, potassium, manganese, zinc, copper
and boron minerals were more evident. No clear change was seen
in phosphorus and calcium. Despite that changes were seen in iron
mineral at the cultivar level, this situation did not present itself in
general averages. When every cultivar is analyzed by itself, there
were clear differences among cultivars. Every cultivar's mineral
element accumulation level has shown variation. Differences among
cultivars' averages have been found statistically significant.
