The results indicate that Ca(superscript 2+) and GA3, single or combined application treatments, promote cucumber seed germination treated with P. harmala alkaloid, increase germination rate, germination vigor and index; as well as α-amylase, protease, lipase, isocitratelyase, nicotinamide adenine dinucleotide kinase and Ca(superscript 2+)-ATPase activities; and GA and CaM content in cucumber seeds; but decrease abscisic acid content. The synergistic effects of combined Ca(superscript 2+) and GA3 on increasing GA and decreasing ABA are oberseved compared with Ca(superscript 2+) treatment.
