PROLIFERATIVE ACTIVITY AND CELL REPRODUCTION IN MERISTEMS OF ROOT SEEDLINGS OF PEA, FLAX AND LENTIL UNDER CONDITIONS OF SCREENING OF THE GEOMAGNETIC-FIELD

The proliferative activity and cell reproduction in meristems of root seedlings of pea, flax and lentil have been investigated under conditions of the geomagnetic field (GMF) by about 10(5)-10(6) times. Reduction of the proliferative pool to the level of 68-75% to cells has been observed, whereas under GMF conditions it was 90-96%. The lengthening of the total cell reproductive cycle was registered at the G1-period expanse for all the examined plants and also the G2-period for lentil and especially for flax, as the lengths of other periods of the cell cycle were standard. It has been shown that the proliferative activity of generative tissues was that of a sensor giving evidence about the GMF significance for normal development of plants.
