Abstract: Most of plant development, physiological and metabolic processes are regulated by not only soluble sugars such as glucose and sucrose, but also by other signal molecules, such as phytohormones. The investigation of flowering induction, considering the influence of vernalisation duration and photoperiod on morphogenesis stages and accumulation metabolites in two Festulolium cultivars ’Vėtra’ and ’Punia’ was carried out at the phytotron complex of the Plant Physiology Laboratory, Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2011-2012. The data revealed impact of vernalisation and photoperiod on accumulation of both types of assessed metabolies, i.e. phytohormones and saccharides, and thus confirmed their substantial role. 90 short-day vernalisation induced the highest total phytohormone content in ‘Vėtra’, when plant achieved tillering stage and was going for intensive growth when growth regulators will be important in the metabolic regulation. The highest phytohormone content was recorded after long –day 130+20 day vernalization at VII and IV organogenesis stages of ‘Vėtra’ and ʽPuniaʼ respectively. Saccharides content significantly depended on photoperiod and temperature during vernalisation and was different in ’Vėtra’ and ’Punia’
