Abstract:Tests were carried out with regard to the size of intercellular spaces both in leaves and in the underground parts of plants on severa! species of the. genus Festuca and Poa.Range I: F. gigantea -F. arundinacea -F. pratensis -F. rubra -F. heterophylla -F. ovina.Range II: P. palustris -P. pratensis -P. compressa -P. annua. This work forms to a certain degree the supplement of B a u m a n n and K l a u s s' researches (1955), and its aim was to determine whether the capacity for growth of roots in a given well determined level of soil moisture for several species of grasses (at identical of high moisture soil conditionsl has any connection with the size of aerial system of the given species. Cultures of above species were carried out in experirnental vases in which the distance of water surface from surface of soil amounted to 30-40 cm. The size of intercellular spaces in leaves, roots and underground rhizomes was tested by means of the vacuum-filtration method and calculated in proportion to the volume of given organ .It was established that ranging of the tested species from genus Festuca and Poa finds its motivation in the morpho-physiological reaction of the particular species -namely in the capacity for creating a convenient intercellular spaces system. In the range of the genus Festuca the decrease in the general size of intercellular spaces between extreme species is 1,8 times than in the range Poa.The difference at the size of spaces between extreme species in the range, proves to be nearly two times greater for the underground parts than for leaves. It proves that the reaction of underground parts of plants is stronger than that of parts above ground (leaves). On basis of her present and previous works the author states that all species of grasses submitted to testing are characterised by the highest percentage of intercellular spaces in leaves, a lower one in roots and principally the lowest one in rhizomes. The author points out that the „coefficient" of the relation of plant to soil aeration i. e. the so called „size of intercellular spaces" - can be useful in research work analysing the relation of plants to their surroundings.
