Attempts to influence flowering in Ananas comosus (L.) Merr. have involved experiments with certain synthetic phytohormones, including a-naphthaleneacetic acid, naphthaleneacetamide, naphthlenethioacetamide and a cmmercial product known as Fruitone. It has now been established that flowering can be induced in advance of the normal period or delayed until much later by the use of appropriate concentraions of these chemicals. Typical data are given. Low concentration of a_naphthaleneacetic and (the compound used most extensively) applied as foliage sprays induced formation of inflorescences in advance of the normal period, but high concentrations, particularly when applied in solution at the apex, delayed flowering far beyond that of the controls. The faet that natural flowering of a uniform fall planting of slips oceurs at fairly definite season made it possible application of the substances at desired intervals prior to normal differentiation of the inflorescence. |
