Abstract: [eng] [cze]
Brassinosteroids are steroid phytohormones with a wide range of effects. They improve survivance of plants exposed to drought stress, increase their resistence and yield therethrough. They regulate the response of plants directly (via synthesis of metabolits) and/or indirectly (via the induction of antioxidant compounds and enzymes), often in interaction with other phytohormones. Experiments studying influence of brassinosteroids on response of plants stressed with water deficit differ in several parameters. Their correct interpretation is complicated conseguently. Brassinosteroidy sú steroidné fytohormóny so širokým spektrom účinkov. Pri vystavení rastlín stresu suchom zlepšujú ich prežitie a zvyšujú odolnosť, a tým aj výnos. Odpoveď rastlín regulujú priamo (syntézou metabolitov) a/alebo nepriamo (indukciou antioxidačných zlúčenín a enzýmov), často v interakcii s inými fytohormónami. Experimenty študujúce vplyv brassinosteroidov na reakciu rastlín stresovaných vodným deficitom sa líšia v rôznych parametroch. Ich správna interpretácia je preto zložitá.
