    Okresy krytyczne w gospodarce wodnej rzepaku jarego

    In the years 1957-1960 pot experiments were carried out to examine the periods of the critical water point of two summer swede-like rape varieties: Mazowiecki and Bronowski. 3 combinations with stabilized soil moisture (25, 40, 70 % of full moisture capacity) have been employed during the whole vegetative period and 5 combinations with alternating moisture stages in 5 different subperiods of vegetation. The Mazowiecki rape proved vulnerable to drought in the phase between germination and shooting, and in the time of blooming. The Bronowski variety, on the other hand, showed the same symptoms but in the phase of rapid growth and ripening. The experiment has shown that Mazowiecki rape proves more resistant to drought than the Bronowski variety and thus more suitable for planting in the natural conditions of West Pomerania.

    Wodne okresy krytyczne w rozwoju lnu włóknistego

    In the years 1957-1961 pot experiments were carried out to examine the influence that various stages of soil moisture exercisy upon the development and yield of flax of the LCSD 210 variety. The experiments involved 4 moisture combinations (20, 30, 50 and 70 % of full water capacity) and 16 other combinations in which drought was employed (20 % of soil moisture) and were carried out in one the vegetation subperiods. It has been found that flax cropped best when a moisture stage of 70 % was existent during the whole vegetative period, and that the critical water points of the mentioned plant occured in the subperiod of rapid growth.
