Turkish Journal of Agriculture and Forestry
Sodium chloride (NaCl) treatments were conducted on strawberry plants (Fragaria x ananassa cvs. Camarosa and Chandler) grown under greenhouse conditions. Modified Hoagland solution (one-third strength) containing 0 (control), 8.5, 17.0 and 34.0 mM NaCl was applied to the plants for 6 months. High NaCl concentrations caused serious reductions in growth parameters such as fresh weight (FW) of leaves, stems and roots, leaf area and the number of leaves. Addition of salt to the growth medium caused a reduction in stomatal conductance (Gs) and transpiration rate (E) of Camarosa. Saline water up to 34 mM NaCl did not have any influence …

Assessment Of Day-Neutrality Scoring Methods In Strawberry Families Grown In Greenhouse And Field Environments, Sedat Serçe, James F. Hancock
Turkish Journal of Agriculture and Forestry
A strawberry plant is considered day-neutral if it can form flower buds under both long and short day conditions; however, researchers use different methods to score day-neutrality. We studied the relationship among several different evaluation methods for day-neutrality and analyzed the possibility that greenhouse screens can be used to predict field flowering performance. The evaluation methods included: 1) flowering within 100 days from germination in a greenhouse; 2) flowering during the first summer after planting in the field; 3) flowering under both short and long days in the second year in a greenhouse; and 4) flowering under both short and …
