A chaotic and linear spatial display of movement of globular objects is reported for the first time in themyctoplasm of sieve tubes of Hevea brasiliensis where a large number of globular objects occur in a dynamicsystem.The sieve tubes recently differentiated from the phloem mother cells of the cambial zone showed anear uniform distribution of globular objects in a continuous state of motion. The objects measured anaverage diameter of 1.6μm with a density of 200 per 1000μm2 in the viscous medium. Speed of the movingparticles recorded through the video graphs was reduced to five per cent and found that these objectsdevelop spatial patterns with respect to both loci and time within the sieve tubes. At a time, the pattern ofmovement at different loci is different and are not repeating and hence across the loci the displays arechaotic. In each locus as the time proceeds, a linear pattern develops that exists for about 152 millisecondswhich are considered as a block. The pattern in a block remains stationery except at 52nd and 102nd millisecondsin which two intermittent oscillating vibrations develop. The intermittent oscillations remain for onemillisecond and are identical in display but differ from the predominant pattern of the block. There areblocks where the oscillating vibration repeats more than what is common for all the blocks and displayedin the 50th and 100th milliseconds. As the patterns are repeating intermittently in a regular manner within ablock, the motion along the block is linear. The direction of the moving objects to form the intermittentoscillations in a block gives an indication on the direction of spatial pattern to be formed in the forthcomingblock. The patterns are chaotic as far as blocks are concerned where the spatial patterns are not repeated.The timing for both linear and chaotic spatial pattern in the sieve tube is the same for more than 250subsequent patterns studied indicating that these features seem to be predetermined and specific for aplant.
