Ajania pacifica has been gaining popularity as a pot plant. It is closely related to the chrysanthemum, and may become an interesting alternative for it, the more that the cultivation of both species can be carried out simultaneously. The aim of this study was to assess the growth and flowering of ajania as a result of pinching and the day length of pinched plants. The present research involved the use of Ajania pacifica, ‘Silver and Gold’ and ‘Bea’ ‘Benetti’ and ‘Bengo’ (of Bellania group). The first cultivation was made in the long-day glasshouse. Having been planted into pots, the plants of each cultivar were divided into groups: non-pinched and pinched once, and the last group: further divided into: allocated to immediate cultivation exposed to short day and those which, before the second stage of cultivation – plant darkening for the period of two weeks, were grown further under long-day conditions. Not all the cultivars reacted in the same way to pinching. In ‘Bengo’ the pinched plants formed buds and started flowering at a similar date as the non-pinched ones, in ‘Benetti’ and ‘Bea’ the delay was inconsiderable and in ‘Silver and Gold’ the buds appeared 5 to 12 days later. The plants growing longer under long-day conditions were higher, wider, with longer and wider corymbs, more inflorescences and their life was longer.
