The florigen mystery
AbstractIn order to obtain flowering, different applications of chemicals on plants were tested by several researchers. Substances that were tested were, amongst others, auxin, gibberellin, cytokinin, abscisic acid, prostaglandin; melatonin. All had an effect on flowering. With the aid of molecular-genetic research it was established that the product of certain genes, namely CONSTANS (CO) and FLOWERING LOCUS T (FT) could be the flowering stimulus. It could be a peptide or mRNA.
