Effect of boron and methionine on growth and ion content in kiwifruit shoots cultured in vitro

Abstract

The growth of kiwifruit explants was affected by boron (B) and methionine (Meth) in the culture medium. The longest shoots, the greatest number of shoots and the highest amount of fresh mass per explant were produced in Murashige and Skoog medium with 2 mM B and 2 μM Meth. Furthermore, by increasing B concentration in the culture medium from 0 to 2 mM, an increased rate of shoot proliferation was observed for the various Meth concentrations employed.
