Abstract: Yield of winter wheat depends on a lot of factors: climate, soil condition, variety, seed quality and growing technologies. Whereas processes of photoynthesis and amount of chlorophylls in plants are strongly affected by climate change: temerature and humidity change. This experiment was held on 2016-2017 year in Aleksandras Stulginskis university Experiment station to compare and determine the dynamics of physiological parameters among winter wheats sown on different dates. Object A: winter wheat varieties `Skagen` and `Julius`, object B: different sowing dates: 09-08; 09-15; 09-22; 09-29; 10-06; 10-13. Winter wheat sown on 10-06 and 10-13 didn‘t survived during the winter so it is not investigated further. The results shows that different sowing date had no essential effect for chlorophylls a and b relation. While sowing date had crucial effect for amount of ry matter. Winter wheat leaves that were sown earlier where determined to have essentialy higher amount of dry matter. Also winter wheat variety `Skagen` showed essentialy higher results than winter wheat `Julius`
