Özet

In Ctenanthe setosa we studied changes in apoplastic and symplastic sugar, prolific, ions and organic acids under drought stress causing leaf rolling Leaf extractions were made at visually Judged leaf rolling stages (not rolled, slightly rolled. strongly rolled. completely rolled) Glucose and sucrose content increased in the symplast Glucose declined during leaf rolling in the apoplast. and sucrose was not present Symplasitc and apoplastic proline content increased during leaf rolling, citrate increased in both compartments. and imitate increased in the symplast but declined in the apoplast Symplastic and apoplastic K(+) declined during rolling Ca(2+) increased at slightly rolled stage but then began to decrease in both compartments Na(+) level increasing in the symplast but decreased in the apoplast Cl(-) decreased in both compartments during rolling Glucose. proline, Na(+) and K(+) are preferred for osmotic adjustment during leaf rolling under drought
