At the influence of millimetric radiation with wavelength of 5,6 mm; density of stream of capacity of 6−10 mwt / sm2 and several minutes’ expositions on dry and presoaked seeds of tomato, castor-oil plant and dope we observed stimulation of sprouting energy and seeds germinating power, change of protein synthesis and enzymatic activity of sprouts and also decrease of the number of chromosomal infringements in cells of rootlets. It has been drawn the conclusion that water is a primary receptor of millimetric radiation in seeds of plants.
