Effect of AgNps and different sources of Zinc on rooting and acclimation of strawberry (Fragaria ananassa Duch) cv. Rubygem in vitro

Abstract

This study was conducted to examine the effect of adding different concentrations of nano silver nitrate (0, 5, 10 and 15 mg L-1) and zinc source {traditional(0.86mg L-1 as ZnSO4.7H2O) and nano zinc 0.086mg L-1 as Zinc oxide) to the specifies medium of rooting strawberry (Fragaria X ananassa Duch) cv. Rubygem, in addition to testing the efficiency of nano silver nitrate and zinc source on successful percentage of cultures adapting stage. Results revealed that highest rooting percentage, root numbers, roots length, leaves content of total chlorophyll and macro nutrients (N, P and K) were achieved the highest average at 10mg L-1 + nano zinc treatment. The source of cultures resulting from rooting stage affected the plant survival at acclimatization stage. The treatment 10 and 15mg L-1 of nano silver nitrate + nano zinc achieved 100% success percentage.
