Abstract:
The Brassica campetris(rape)‘Longyou 9’ seedling was selected as experimental material,and the low temperature conditions were stimulated with low temperature incubator.The Brassica campetris(rape)‘Longyou 9’ seedling were treated with compound biological preparation as foliar application to study the effect of low temperature stress on it.The results showed that the composite exogenous substances of cold resistance of plant water solution for the base configuration treatment could make the rape seedlings under the stress of low temperature (0±1)℃ maintain a relatively high superoxide dismutase (SOD)activity and the contents of glucose,soluble protein,chlorophyll and proline (Pro),reduce the malondialdehyde (MDA)accumulation,improve the cold resistance of Brassica campetris(rape)‘Longyou 9’.Composite exogenous substances could increase the Brassica campetris(rape)‘Longyou 9’ seedlings fight cold ability,effectively reduce Brassica campetris(rape)‘Longyou 9’ seedling frost damage.
