Screening of wild strawberry germplasm for iron-deficiency tolerance under hydroponic conditions

Cultivated strawberry has been originated from hybridization between Fragaria chiloensis and F. virginiana. The progenitor species exhibit significant genetic diversity. Growth attributes of their responses to several stress factors have studied. However, iron-deficiency tolerance (FeDT) different merely tested under hydroponic conditions. This study evaluated FeDT 23 genotypes belonging super-seed collection Two (one Fe-deficiency-tolerant one sensitive) were selected screening experiment physiological morphological mechanisms playing role in determined. Plant parameters associated with FeDT, i.e., pH the growth medium, root Fe reductase activity, total active concentration shoot was recorded. Fe-efficiency subspecies varied 51 98%. efficiency values also among subspecies. AukeLake RCP37 highly resistant sensitive Fe-deficiency, respectively based on values. A relationship observed genotypes. Acidification nutrient solution activity closely related high iron concentration. Our findings indicated existence a close uptake root-to-shoot translocation Fe, which ultimately contribute greatly
