Abstract

The plantlets of banana(Musa acuminate(AAA group)`Dwarf Cavendish`Brazil`)suffered from chilling stress under the artificial lowering of temperature in the phytotron. It is studied that ABA,PP 333 and brassinolide(BR)have some effects on the POD activity and REC of leaves in banana plantlets during the period of chilling stress. The experiments show that spraying ABA, PP 333 and Brassinolide on the leaves of banana plantlets can improve the peroxidase(POD)activity and reduce the relative electric conductivity(REC)at the period of chilling-stress and recovering. The appropriate concentration is ABA 20~25 mg/L,PP 333 15~30 mg/L, BR 0.9~1.5 mg/L?
