Changes in Mineral Nutrition Levels during Floral Transition in Strawberry (Fragaria x ananassa Duch.)
S. Eshghi and E. Tafazoli

Flowering is an important step in crop production. Under flower-inducing conditions, biochemical or physiological changes can be recognized. Changes in mineral nutrient contents during flower bud induction and differentiation in strawberry have not been thoroughly investigated. In this study, runner plants were potted in 18 cm diameter pots and grown under non-inducing conditions (high temperature; long day). After the plants were established, half of them were kept under flower-inducing conditions (low temperature; short day) for 3 weeks, then brought back to non-inductive conditions. To determine N, P, K, Ca, Fe, Zn and Mn contents, leaves of induced and non-induced plants were collected every 3 d during 3 weeks and thereafter weekly for the period of 7 weeks. The results indicated that in induced plants total nitrogen increased from 3 to 18 days after the start of the short day treatment (DASST) and after that decreased. The amount of Ca in leaves of induced plants increased at 3, 9 and 28 DASST. The amount of Mn in leaves of induced plants was significantly higher than those of non-induced plants at 3, 9, 12 and 18 DASST. Since N, Ca and Mn were significantly higher in induced plants it seems that these elements have a decisive role during floral transition in strawberry.
