Abstract: |
A…pot…experiment…with…two…barley…varieties…Taixin9425…and…Naso…Nijo…was…conducted…to…study…the…
regulatory…effects…of…5-azacytidine…and…sodium…butyrate…on…adventitious…root, dry…weight, proline…and…malondialdehyde
(MDA)during…seeding…stage.…Waterlogging…index…analysis…showed…that…Taixin9425…was…waterlogging…tolerant…variety.…
The…waterlogging…index…of…Taixin9425…and…Naso…Nijo…declined…by…4.90%…and…15.22%…after…5-azacytidine…treatment.…The…
MDA…content…in…Taixin9425…and…Naso…Nijo…declined…by…12.83%…and…34.68%…after…5-azacytidine…treatment.…The…proline…
declined…in…Naso…Nijo, while…increased…in…Taixin9425…after…5-azacytidine…treatment.…The…treatment…of…sodium…butyrate…
had…no…effect…on…waterlogging…index…in…both…Taixin9425…and…Naso…Nijo.…Compared…to…the…waterlogging, sodium…butyrate…
treatment…significantly…increased…the…content…of…proline…and…MDA…in…both…Taixin9425…and…Naso…Nijo.…The…results…indicated…
that…5-azaC…could…enhace…barley…waterlogging…tolerance…during…seeding…stage, while…sodium…butyrate…had…no…effect…on…
regulating…the…waterlogging…tolerance…of…barley. |
