ABSTRACT:
Plant host acceptable microorganisms, which are ice nucleation deficient and use at least one nutrient from the plant also used by ice nucleating native microorganisms, are applied to a plant part at an early stage in the growth cycle. The multiplication of the native ice nucleating microorganisms is inhibited, so that under normal frost conditions encountered in the field, frost damage is substantially diminished. The non-nucleating microorganisms may be obtained by special selection procedures, selecting from naturally occurring microorganisms or mutagenized microorganisms, where additionally the organisms may be transformed to provide for other desirable properties.
The following organisms have been deposited at the A.T.C.C. on Aug. 13, 1981; A5-01, A5-05-1, A5-06, A5-10-1, A5-26, and A4-2B-10.
